Leonardo Da Vinci - Research Paper Example His extensive art work has been split up and most of it is wasted as it was on paper. Like his vast variety of themes and genres, he used different medium for his artistic works. However, no matter which medium he uses, the quality of work remains the same. He used oil paints, pen, tempera etc. on walls, paper, poplar and gesso proving that art is not reliant on a single medium. The sfumato technique admired me the most. Leonardo’s expertise in this technique gave lifelong charm to his artistic works. It creates a smoky or cloudy look which may not be incorporated in other artists’ work that well (Leonardo & Goldscheider, 1959 pp. 173-177). The most important thing is the reputation and overwhelming distinction given to Leonardo’s work. Mona Lisa is one of the first art works that appear in people’s mind when they think about art. Having heard about Leonardo’s artistic abilities, I chose writing on his art work. His placement of objects, color choices, expertise of giving prominence to one object and making less prominent the other, his ideas and knowledge of color art provides a deeper insight of his work. His art cannot be categorized in purely impressionism, art nouvea or any other. The distinct qualities of his works can be identified by simply analyzing two extremely different pieces of his art like ‘Vitruvian Man’ and ‘last

Law - Essay Example critically evaluate the impact of the decision by the House of Lords in White v White1 in relation to division of assets and financial provisions on divorce. In particular, this paper critically reviews the White decision and considers the extent to which the decision has actually culminated in a revolutionary change in the law relating to matrimonial property and financial provision on divorce. Moreover, I shall comparatively analyse the UK legal position with the approach in other jurisdictions where appropriate. From a family law perspective, the issue of rights to the family home have continued to be problematic and decisions in ancillary relief proceedings were addressed by the House of Lords’ decision in White v White2. This decision changed the approach to assessing financial settlements on divorce and introduced the â€Å"yardstick of equality† principle as a means to ensure fairness in the division of assets between divorcing couples. Whilst heralded as a welcome decision in introducing some much needed clarity to the division of assets on divorce3, it has been argued that such an approach is inherently dogmatic in failing to specifically address the division of rights to the family home particularly where children are involved4. Although the reasoning in White v White specified that there was no presumption of equality on divorce, if the court intended to depart drastically from an equal splitting of assets they should have satisfactory justification for doing so. Furthermore, the governing legislative provision in this area of law is the Matrimonial Causes Act 1973 (MCA) and section 25 of the MCA provides the court with a very wide discretion of factors to take into account on division of assets, with the welfare of a child being paramount5. As such, it is submitted that the overriding statutory requirement to consider the interests of the child inherently limits the application of White v White to cases where children are not involved as the

Importance of Population Control

Importance of Population Control Population control is a way in which the rate of population growth is changed, which has been made possible by limiting birth rates. Initially, population development has genuine impacts on the environment. As we all know we expend materials and vitality from earth and after that return high temperature and squanders to earth. It is just coherent to say that there is a breaking point at which these squanders can go to our planet without having a genuine impact on people. All things considered, because of the way that population development aggravates every one of those terrible circumstances, and the control of population thickness can purchase us some time to control whatever remains of the issues, one need to prescribe the control of population explosion. As the human numbers increment, weakening of water quality and annihilation of animal and plant groups expand as well. Water pollution has been mostly brought about by population development. People devoured, put away and redirected water and utilized it to divert squanders without respect to wellbeing or ecological results, which were viewed as insignificant (Turner II, 1990). These human movements in addition to population development and the need has thus the weakening of water quality in streams, with impacts by human activities and advancement on or near them. As said at one time animal and plant species are at risk because of population blast. The genuine impacts of population development apply even to the secured areas of this planet. Indeed, in the USA, that has a measurable low population, extension, the regular parks encounter a misfortune of animal groups and territory corruption because of monstrous amounts of individuals and their activities. Be that as it may fast development of human numbers does not have impacts just on the environment by and large additionally causes overexploitation of characteristic resources and gives weight on food supplies. Therefore, it wont be long until we watch a momentary decrease in our living measures, or as it were a decrease in our personal satisfaction. On the off chance that everybody on the planet today might embrace a North American lifestyle, natural resources would rapidly vanish. Fortunately most countries are still cautious. They will need to remain so while enhancing their expectation for everyday comforts. It will be important that others in rich countries check their utilization and squanders. Our survival relies on upon population control and additionally a finer administration of natural resources. Being constrained in amount, natural resources need to be overseen as needs be. Another administration of the planets resources must be arranged. Notwithstanding the population increment, famines have gotten less continuous in the previous two hundred years, because of incredible farming yields, and global economy. In the last few years a few African nations have been influenced by famine. The reasons were all because of political issues, including common wars, that disorder the economy, deaden transportation, and avert crisis food drops to achieve their objective. Famine is no longer due to a global food shortage. Another illustration is oil. Forecasts of the world utilizing up all its oil have been around for no less than 70 years. They arrived at their crest in the 1970s with the oil emergency brought on by the Oil and Petroleum Exporting Countries endeavor to raise oil costs by voluntarily constraining supply. As the value climbs, in any case, the amount requested by purchasers diminishes. As the cost of gasoline increments, for instance, shoppers will have a tendency to buy more fuel proficient vehicles or discover cars which utilize fuel sources not subject to oil. This does not require any incredible jump in engineering; there are now various options to oil which might get to be monetarily attainable if the cost of oil ever hopped fundamentally. Natural gas, for instance, is liable to trade oil as the primary wellspring of vitality for whats to come at some point in the one century from now. Particularly land, forest and water is a portion of the fundamental resources that are debilitated by development of population thickness. Since population development has extended significantly throughout the most recent 500 years, as bigger amounts of individuals required more food supplies and items from common resources and agricultural exercises, more individuals involved bigger land spaces in huge urban regions. Population development in todays reality, hence, assumes an indispensable part to changes in the land. Developing need for food supplies and wares helped the development of croplands everywhere throughout the world and to the utilization of regular resources. Work strengths, which were accessible, come about to land-clearing, modification and misfortune of the lands quality. All inclusive, population development is primarily answerable for land weights. Forests -one of the best characteristic resources- have additionally encountered significant harm because of huge population development. As an aftereffect of the quick human fruitfulness, forests have been changed either into agricultural lands or into open zones in which towns and urban areas now exist so as to manage the alleged urban population. Likewise in numerous nations of the creating scene, population numbers additionally multiplied between 1950 and 1980. Consequently, weights on the forest have been expanded as they turn into one of the last sources of new land for the development of arable and pasture, for fuel wood for warming and cooking and actually for industry, and as a wellspring of hard cash from sending out logs and wood chips. Separated from land and forest population development has connected weight with resources of water. Population development has thus the diminishing of new water resources; people apply weight on water amount through water needs for survival , cleanliness and farming. All developing countries have moderate developing populations. It is the countries with quick population development that are experiencing fast environmental progressions and issues. Numerous individuals accept that we are headed straight into a world population emergency. The population development in Third World Countries is getting to be harder to control. Most quickly developing countries have populations excessively expand to control. These countries experience fast, ecological changes by devouring their regular resources and financial resources, speedier than they could be processed. This can prompt expanding demise rates from starvation and the settling for what is the most convenient option. These quickly developing countries that have high populations might in the long run for all time decrease the convey limit of their country. There are numerous reasons why population development has abated now and again and climbs on occasion. Case in point, in countries where the majorit y of the women are uneducated, there is restricted access to wellbeing administrations and not many individuals are financially secure, populations have a tendency to be higher. A significant number of these countries have poor standards of living, which prompts the spread of infection, starvation, poor sanitation and terrible ecological and environmental conditions. Others components incorporate absence of family planning, absence of training and the absence of information about birth control. The point when population moderates, numerous offer credit for elements of population control. Most governments around the world have laws intended to moderate population development. The legislatures that have the resources to implement these laws have been successful in moderating population development. There are numerous gatherings and associations in America that help creating countries, by supporting and teaching individuals in family planning and birth control. An alternate system for population control that is dubious, however, energized in numerous countries is male and female sterilization. Late inquiries and remarks concerning human rights and admiration for individuals have come up. Issues emerge when mistaken data are given about sterilization and its outcomes to individuals in third world countries that are not taught enough to know the contr ast. This manifestation of birth control takes away all obligation from multiplication. Today, regardless of its discussion, abortion is constantly recommended more as a strategy for population control. The most prevalent technique for abortion being pushed today is a chemical substance called Anti-Pregnancies. These incorporate immunizations and infusions, for example, Depo-Provera, Noristerat, Oestro-progesterone or most normally known as RU486. The point when taking a gander at those countries that have restricted access to birth control or no information about present day types of birth control, and those countries that do hone population control, we see more instances of infanticide. In spite of the fact that this is still drilled in some third world countries, infanticide is all the more ordinarily polished when a female child is conceived. Recognizing all the above data and presentation of proof, we must comprehend that fast population development is surely an immense danger to our lives and our planet. We must be educated and we must make legitimate move. Trough legitimate instruction, family planning, nation strategies and backing of logical examination population thickness might be effectively controlled and our future will appear to be more prosperous. Turner II, B. L., Kasperson, R. E., Meyer, W. B., Dow, K. M., Golding, D., Kasperson, J. X. Ratick, S. J. (1990). Two types of global environmental change: definitional and spatial-scale issues in their human dimensions.Global Environmental Change,1(1), 14-22. URL: http://www.sciencedirect.com/science/article/pii/095937809090004S Illumination of a few issues in the human sizes of global environmental change is key to the formation of an adjusted research motivation. Global environmental change incorporates both systemic changes that work globally through the significant frameworks of the geosphere-biosphere, and combined changes that speak to the global aggregation of limited progressions. An understanding of the human sizes of progress obliges consideration regarding both sorts through research that incorporates discoveries from spatial scales running from the global to the nearby. A local or meso-scale center speaks to an especially guaranteeing boulevard of methodology.

Food Production: Using Lean Manufacturing Principles

Food Production: Using Lean Manufacturing Principles The main objective of the factories was to achieve high economic growth. The improvement in productivity has become need of food industry to take the competitive advantage of global market. The big problem or challenge to food industry is identifying the wastes and meet the market price by maintaining a good profit. The only solution is to reduce total production cost. Lean manufacturing is systematic approach to identify and eliminate the waste through continues improvements. This paper discusses how the production principles of lean manufacturing can be applied in food production to increased production efficiency and improvement productivity and quality. This paper first presents the lean concept and presents the implementation of lean manufacturing system on some organization. Three main factors that food production factories fear, poor and tacky quality, increase of production cost, increase in lead time. Production improvements should be based on the improvements of processes as well as operation. Problems can appear in any of the basic elements that constitute the production area. (Materials, workers, machines and tools, energy, methods, product). So I focus on lean manufacturing the program can help to improve in this area. Problem Statement Why and how companies should implement lean manufacturing in food production ? 1.3 Importance of the study The main aim of the study is to present the main idea of the Lean manufacturing system, and the benefit of applying it in the field of food production, and identifying the kinds of wastes in production process, and the effect of the Lean manufacturing on food production and presenting some examples of successful companies that implemented the Lean manufacturing. 1.4 Research Questions When organizations implement lean manufacturing, it is more likely to make positive on food production? 1.5 Research Approach The data collected in this research was stemmed from previous published articles. And present a successful example from companies will be achieved good results after implement lean manufacturing program. The main target of this paper is to be applied as guideline to food production companies in Egypt. II. Literature Review: 2.1 History of Lean Manufacturing. Many of the concepts in LM or lean production originate from the Toyota Production System (TPS) and have been implemented progressively throughout Toyotas operations starting in the 1950s. In 1980s Toyota had increasingly become famous for the efficiency with which it had implemented Just-In-Time (JIT) manufacturing systems. Now, Toyota is often considered one of the most efficacious and influential manufacturing companies in the world and the company that put the standard for best practices in LM. LM has increasingly been applied by leading manufacturing companies throughout the world, lead by the major automobile manufactures and their equipment suppliers. Lean Manufacturing is becoming an increasingly significant topic for manufacturing companies in developed countries as they try to find procedure to compete more effectively versus competition from Asia. 2.2 Lean Manufacturing. Lean Manufacturing is a set of tools and methodologies that aims for the continuous elimination of all waste in the production process. The main benefits of this are lower production costs; increased output and minimum production lead times. Some of the goals include: Utilization of equipment and area Use equipment and manufacturing area more efficiently by eradicating bottlenecks and maximizing the rate of production though existing equipment, while reducing machine downtime. Defects and wastes Reduce defects and unnecessary physical wastage, including surplus use of raw material inputs, preventable defects, and costs associated with reprocessing defective items and dispensable product characteristics which are not required by customers. Flexibility Have the ability to produce a more elastic range of products with minimum changeover costs and changeover time. Labor productivity Improve labor productivity, both by reducing the inactive time of workers and ensuring that when workers are working, they are using their effort as productively as possible Output Insofar as reduced cycle times, increased labor productivity and removal of bottlenecks and machine downtime can be completed, companies can generally significantly increase output from their existing facilities. Inventory levels Minimize inventory levels at all steps of production, particularly works-in-progress between production steps. Lower inventories also mean lower working capital requirements. Cycle Times Reduce manufacturing lead times and production cycle times by reducing waiting times between processing stages, as well as process preparation times and product. Most of these benefits lead to lower unit production costs for example, more effective use of equipment and space leads to lower depreciation costs per unit produced, more effective use of labor results in lower labor costs per unit produced and lower defects lead to lower cost of goods sold. 2.3 The Five Lean Principles The critical beginning point when changing a traditional production line into a Lean process is the determination of value from the customers points of view, which is significant as the goal of the Lean process is a line where every activity adds a specified customer value to the product. Having identified the value of products, the second step is to identify and map the value stream in the production line. Value stream mapping refers to the mapping of a products route and is explained in more detail further. The third principle is the connection of value creating activities in a continuous flow process. Every dilemma or batch and queue process must be avoided to obtain an uninterrupted flow throughout the production. The ideal production Flow is drawn on a map, and existing procedures changed and equipment relocated to reflect this. The fourth principle is not to produce anything upstream unless it is needed downstream. The principle is in contrast to batch and queue procedures, as seen in mass production, and aims to reduce the amount of resources locked up in inventories. It implies that production must be just-in-time, both internally between processes and externally when delivering products to the End-user. The fifth principle is about pursuing perfection through a continuous improvement. This is not only about creating a product that the customer requires with a minimum of defects, but also includes the perfection of every action in connection with the production process. It involves all employees as they know procedures the most and are closest to make suggestions for improvement. The involvement of everyone in the continuous improvement is what makes Lean a philosophy improving working processes is integrated in job routines. (Womack Jones 2003; Bicheno 2004). 2.5 The kind of waste in food production: Overproduction Producing elements for which there are no client requirements. The Lean principle is to use a pull system, or producing goods just as clients order them. Service organizations operate this way by their very nature. Industrialization organizations, furthermore, have historically operated by a Push System, building products to stock, without firm customer orders. Anything produced beyond the customer demand (safety stocks, work-in-process inventories, etc.) ties up valuable labor and material resources and hence is a waste. Waiting Time during production (service) when no value is added to product (service). This includes waiting for material, information, equipment, tools, stock-outs, lot processing delays, equipment downtime, capacity bottlenecks, etc. The Lean principle is to use a just-in-time (JIT) system- not too soon, not too late. Transportation Unnecessary moving and handling of parts. This includes transporting work-in-process long distances, trucking to and from an off-site storage facility. Lean demands that the material be shipped directly from the vendor to the location in the assembly line where it will be used. Material should be delivered to its point of use. Over-Processing Unnecessary processing or procedures than necessary to meet customer demand. Common examples multiple inspecting. Statistical process control techniques can be used to eliminate or minimize the amount of inspection required. Value Stream Mapping is another lean tool that can be used for this purpose also. This tool is frequently used to help identify non-valued-added steps in the process (for both manufacturers and service organizations). Excess Inventory Excess raw material, or finished goods. Inventory beyond that needed to meet customer demands negatively impacts cash flow and uses valuable floor space. Defects Scrap, rework, replacement production, and inspection. Production defects and service errors waste resources in four ways. First, materials are consumed. Second, the labor used to produce the part (or provide the service) the first time cannot be recovered. Third, labor is required to rework the product (or redo the service). Fourth, labor is required to address any forthcoming customer complaints. Total Quality Management (TQM) is one of the lean tools that can be used to for reducing defects. Excess Motion Unnecessary motion of people or equipment that adds to value to product (service). This is caused by poor workflow, poor layout, housekeeping, and inconsistent or undocumented work methods. Value Stream Mapping is also used to identify this type of waste. Tools like 5S, comfortable workspace design can be used to eliminate this waste. Underutilized People Underutilization of mental, creative, and physical skills and abilities of employees of the organization. Some of the more common causes for this waste include organizational culture, inadequate hiring practices, poor or non-existent training, and high employee turnover. 2.6 The Policy to reduce the waste Policy to reduce waste consists of several systems 1- Reduced Set up Time It reduced the time required to adjust the machines to produce a different product. A long time in the control of the machine means the need to produce large quantities of the same product and thus prevents us from reducing the size of the order, which in turn prevents us from inventory reduction and prevents us from the production process of withdrawing. Permission must be reduced machine set time dramatically. 2- Small Lot size Which is the size of the order per batch per production? If the size of each run command (order) significant meaning that we will store a lot of semi-finished materials, which do not want to do because we want to reduce inventory in general 3- Reduced Work in Process An inventory of the materials or parts that have passed the initial stage of production and did not pass to the latter. Reduce inventory this is essential in the philosophy of the policy of reducing losses because of its impact on the coverage of production problems and because it is a money investor. 4- Policy pull Production it means that production on the basis of need for the next stage of production and not on the basis of a specific production plan. The first production engineering stage not only produces and need permission from the production stage next and so on until the end of the production line. There is stacked production between stages. This is also known as Kanban card or card. 5- Quality Control Circles It is a work teams of operators and technicians are studying and solving quality problems and operation and maintenance. These rings are necessary to study the problems and uprooted from their roots and to involve all levels of work in solving problems. Quality control loops is a continuous development of methods Continuous Improvement, which is one of the basics of the Toyota system. 6- Total Productive Maintenance They maintenance system leads to increased availability of equipment and reduce breakdowns. This system is necessary to be able to reduce inventory of semi-finished materials and the implementation of the policy to withdraw production. Must be reduced dramatically sudden failure to implement these policies. 7- Group Technology It is a method designed to manufacture similar products in one place to reduce the transport time and wait in what is known as the cell manufacturing Cells. This method helps to reduce transfer times material from one place to another and make each group of operators responsible for different stages of the production for the same product that they have a kind of full responsibility for the product. 8- Multi Task Employees Meaning that the worker trained to do several tasks instead of one task. This method gives the flexibility to change the functions of working when needed. Note that this system is designed to reach the speed of response to customer requirements and thus there must be flexibility in employment as well so that you can change the functions of Group according to the requirements of the market. This method has a lot to do with technology group, where can one player that is running several machines. 9- Production leveling: Toyota system is designed to reduce the variables and produce small amounts of each product every day, so there is no need to produce large quantities of a product in one day. Reduce the change helps us not to maintain a large stock and makes the production process is running smoothly and regularity without significant changes. 10- Just In Time Purchasing it means of access to raw materials and production supplies when you need them quickly. This procurement policy is needed to reduce inventory and production development and reduce defects in products. To reach that there is a lot of things are applied, such as reducing the number of suppliers and to cooperate with them and compel them specific things in the style of their work. 11- Maintain a work environment 5S: It means arrange and organize and clean workplace and work tools so that you have access to the tools and information is accessible, fast and the site is a good place to work and safe at the same time. This method is called 5S relative to the Japanese words that mean organize and arrange and clean workplace. 12- Total Quality Control: There is a correlation between policies to reduce waste and total quality management both supports the other. To reach to pull production policy has to be to reach high levels of quality. Therefore, Toyota and Japanese companies have applied TQM or total quality control of the most important has been applied is the technical checks parts produced by himself in the sense that the product is scanned during each stage production by the operators themselves. It is the powers of the workers off the production line in the event of a quality problem. 2.6.1 The Benefits of reducing the waste Improved performance indicators such as: à ¢Ã¢â€š ¬Ã‚ ¢ reduce losses to a great extent à ¢Ã¢â€š ¬Ã‚ ¢ high product quality (in terms of compliance with specifications) any low percentage of defective products à ¢Ã¢â€š ¬Ã‚ ¢ Reduced time progress (which is the time to meet manufacturing orders) à ¢Ã¢â€š ¬Ã‚ ¢ high inventory turnover rate à ¢Ã¢â€š ¬Ã‚ ¢ very high flexibility to change production from one product to another à ¢Ã¢â€š ¬Ã‚ ¢ lower the sudden failure of equipment à ¢Ã¢â€š ¬Ã‚ ¢ low additional cost Overhead cost à ¢Ã¢â€š ¬Ã‚ ¢ increase production capacity à ¢Ã¢â€š ¬Ã‚ ¢ high accuracy to meet the supply orders on time for supply à ¢Ã¢â€š ¬Ã‚ ¢ the speed of response to changing market à ¢Ã¢â€š ¬Ã‚ ¢ improvement of financial indicators in the long term, including the profitability à ¢Ã¢â€š ¬Ã‚ ¢ Improved morale of workers 2.7Quality in Lean Manufacturing 2.7.1. Reducing the Defect-Detection Time Gap The most important improvement that is made by a move from final inspections to successive checks to self checks is in the reduction of the time gap between creation of a defect and its detection. Figure 1 show how this time gap shrinks as one progresses towards self inspection Grinder Drill Lathe Mill Figure 1: the time lag includes all operations that happen In Figure 1, the time lag includes all operations that happen to the part after the defect Has been made and before the defect will be detected (more defective parts can be made During this time if the defect is due to a broken machine tool, improper machining method, Or other problems that do not create simply one isolated defect). Lathe Mill Figure 2: the time gap shrinks In Figure 2 the time gap shrinks to the length of time before the operator of the next Machine handles the part. In a job shop, this may be a significant quantity of time and if Parts are produced in batches; often the entire batch may have the same defect. However, In cellular manufacturing this time lag is small, since the queue is only one unit. Lathe Mill Figure 3: the time lag has shrunk down In Figure 3 the time lag has shrunk down to the amount of time that the operator spends On the given operation before he or she checks the part. Self-inspection produces visibility of the problem after the first defective part is made (if it is detectable). Catching defective parts prevents adding more value to parts that will be scrapped or reworked later. Clearly this reduction in time lag can lead to: quicker and easier detection of what the problem is that is causing the defect, reduction in wasted time in the form of value added to scrapped parts, and wasted time spent assembling a part that will have to be disassembled and then reassembled. Overall, quicker elimination of defect causing problems will result in a reduction of the number and cost of bad quality parts. 2.8 Productivity in lean manufacturing 2.8.1 Introduction The lean manufacturing focus on 20 keys I will present only key number 6 method improvement (Productivity) Figure 4 Relationship Diagram20 Keys 2.8.2 Definition Productivity is about how well resources are used. The other area of general consensus is that productivity is about the relation between output and input in any process producing goods or services. Productivity can be calculated as output divided by input P = O/I Where P = Productivity , O = Output and I = Input Output can be measured in different way tones, Kilograms or even output defined as standard minutes or hours 2.8.3 The components of productivity Productivity basically has two components: Efficiency Utilizations Utilization is about whether the resources available are actually used in producing the product or service. That is a machine might be available but if no product is scheduled to be produced then it is not utilized , or if product is scheduled to be produced for only 85% of the available time then utilization is 85% Efficiency . On the other hand, is about how well the resources are used while it is being utilized. The formula for productivity is then: Productivity = Efficiency X Utilization This formula can be expanded: Productivity = Output / Available hours, that is how much did we produce during the time that the resources were available Efficiency = Output / Hours worked, that is how much did we produce during the time that the resources were actually operating. Utilization = Hours worked / Hours available, that is for what percentage of time did we actually utilize the resources. 2.8.4 People. Plant- and process related issues impacting on productivity It is important to understand what issues typically impact on productivity as you can then look for the causes to why productivity is not at the level it should be. If productivity is not at the target level it can be explained in terms of the two components of efficiency and utilization that it can be either an efficiency loss or none utilizes time. This can be because of people, plant or process related issues. The following summary show typical examples of issues impaction on productivity. Efficiency loss: People Work method Work rate Effort ( motivation issues ) Skills Quality of work Plant / Process Speed ,idling ,minor stoppages Quality of product Non Utilized time People Plant / process Market demand Work rate Downtime Changeovers Table 2 issues impaction on productivity 2.8.5 Productivity Improvement an Integrated Approach Productivity improvement cannot be achieved by only implementing Kaizen operation. Figure 5 Productivity Improvement: An Integrated Approach Productivity increase and excellent quality can be achieved at the same time. 2.8.6 Implementing key 6 Implementing kaizen of operation requires the effective use of the CAPDo cycle. The CAPDo cycle is a simple management system for continuous improvement. One a plane for implementation has been drawn up, the actual training needs must be scheduled it is important to check regularly whether training targets have been met, and if not, the reason for this must be analyzed.

The main hypothesis of this paper is that where any implement LM it is more likely to make positive on food production so I present lean principles can applied in meal production to increase the efficiency without reducing the quality of meal prepared. All lean principles and tools may not be equally applicable in food production, but it is important to consider this aspect when discussing the implementation of lean in meal production. Glostrup Hospital is situated in the greater Copenhagen area in Denmark. The central Kitchen is situated inside the Hospital grounds in a separate building, and every day, meals for approximately 1000 patients are produced and distributed from the kitchen. In 2005, the hospitals management took the decision that all services should be Lean, and to cut the costs of meal production, the kitchen was forced to replace cook-serve with cook-chill production and reduce the number of foodservice employees from 71 to 54. This brought about a need to review and optimize the production procedures to maintain both output quantity and quality. The change of production system to cook-chill also had an impact on the end-product quality as recipes and production procedures needed adjustments. Therefore, the systematic evaluation and improvement of product quality was given a high priority in the kitchen. The internal working environment in the kitchen was important to the manager as she insisted on maintaining this as a high priority during and after the rationalization process, and that increased efficiency of production processes was obtained by the optimization of procedures and not by making the staff work faster. Because of these reservations, the implementation of Lean was expected to result in both increased efficiency of processes and improved product quality while ensuring a pleasant working environment for the remaining employees. The implementation of Lean in the kitchen began shortly after the change to cook-chill processing and befo re procedures became routine. The kitchen produces most components of the meals themselves including breads, soups and processed vegetables. Previously with cook-serve production, there were separate production lines for hot meal components, vegetables, baked products, desserts and cold products for these meals, all items were prepared, processed and kept warm until service. Initially, when changing to cook-chill production, the separation of production according to meal was maintained with processed meal components being assembled into meals, packed and stored for up to 3 days before final distribution to hospital wards. The packaging was standardised in two, five or seven portions per pack, and the wards received the portion sizes equal to or the closest number above their actual orders. This practice of standardizing packaging was accepted by the management as a pragmatic practice of cook-chill production. The implementation of cook-chill production procedures called for a system atic evaluation of product quality. A graph on display in the production facility showing the daily number of comments on food quality was chosen as an expression of customer satisfaction with product quality. The number of complaints for each meal component, based on feedback received from wards and patients, was totaled and each day marked on the chart. This procedure was chosen as a way to ensure communication of customer product satisfaction to all employees. An internal quality control system was developed to reflect the need for adjusting recipes to improve meal quality after the change from cook serve to cook-chill production. It consisted of a three-color gradation of product acceptability where red refers to not acceptable; yellow, acceptable; and green, good. The testing of product quality was performed internally in the kitchen, and the products had to obtain a yellow to pass. This system was developed to visualize the progress of adjusting existing procedures to cook-chi ll production. As a result of the implementation the hospital realized some quick financial wins. Revenue increased 19%, eliminate wastes meals from 10% to 5% (England al.2009). 2.9.2 Implementing 20 keys in modern bakeries company (Rich Bake), Egypt. In 2008 modern bakeries company management took the decision that some production process should be lean. The company decided implement 10 keys from 20 keys Key1 cleaning organizing to make work easy. Key 2 Rationalizing the system / goal Alignment. Key 3 Small Group Activities.

Increase productivity from 16KG Man / Hour to 18.5 Kg Man /Hour. 2.12 The enormous obstacles for food production in terms of adopting LM approaches to improvement. There is some problems face the food production companies to implementing lean manufacturing, generally as follows. Lack of a clear vision of the future Lack of patience and follow. Lack of persistent and challenge in leadership. Failure to link the processes in key 6 kaizen operation with normal work. Failure to perceive that lean is a viable strategy to help achieve competitive advantage. Lack of constant visibility by management. Failure of management to take a whole systems view of business and to see the connections between all processes. Persistent focus only on demanding results without a balance focus improving the processes that achieve the results. III- Research Methodology 3.1 Research Objectives The main aim of the study is to present the main idea of the Lean manufacturing system, and the benefit of applying it in the field of food production, and identifying the kinds of wastes in production process, and the effect of the Lean manufacturing on food production and presenting some examples of successful companies that implemented the Lean manufacturing. 3.2 Conceptual Framework Figure 7: LM Conceptual Framework 3.3 Research Question and Hypotheses 3.3.1 Research Questions Why and how companies should implement lean manufacturing in food production? 3.3.2 Research Hypotheses When organizations implement lean manufacturing, it is more likely to make positive on food production? 3.3.3 Independent Cost reduction, waste rate, revenue gains 3.3.4 Dependent Return on investment, profit in organization. IV Conclusion and Recommendation Conclusion Through the study found that there is a potential for the application of lean manufacturing system in food production and that explained by viewing experience hospital central kitchen in Denmark and experience modern bakeries company in Egypt, where the application of lean manufacturing system to gain increased efficiency ,quality, and productivity through the application of tools for lean manufacturing . .

Biological Attack Essay -- essays research papers

Biological Attack   Ã‚  Ã‚  Ã‚  Ã‚  In Living Terrors by Michael T. Osterholm and John Schwartz, the threat of biological attack on the United States is introduced to the public. Using Living Terrors and a number of sources that are extremely knowledgeable on the question of preparedness of the United States to a biological attack, I will argue that the United States is in no way prepared to handle a biological attack on its soil.   Ã‚  Ã‚  Ã‚  Ã‚  Nuclear, chemical and biological weapons are all considered weapons of mass destruction. However, unlike chemical or nuclear weapons, biological weapons combine maximum destructiveness and easy availability. According to Richard Betts, â€Å"nuclear arms have great killing capacity but are hard to get; chemical weapons are easy to get but lack such killing capacity; biological agents have both qualities† (9). In 1993, a study by the Office of Technology Assessment concluded that â€Å"a single airplane delivering 100 kilograms of anthrax spores by aerosol on a clear, calm night over Washington D.C., could kill up to 1 to 3 million people in a three hundred square mile area surrounding Washington D.C.† (Osterholm and Schwartz 9).   Ã‚  Ã‚  Ã‚  Ã‚  Biological weapons are a dangerous threat to the United States. According to Eric Noji, associate director of bioterrorism preparedness for the Center for Disease Control, â€Å"the threat of chemical and biological intentional releases is a clear and present danger† (Fialka et al B1). However, there is evidence that the United States is not taking the threat of a biological attack seriously. The investigating branch of Congress named the General Accounting Office or GAO, â€Å"charged that the government has failed to properly manage the medical stockpiles developed to protect the public from the scourge of potentially devastating biological weapons† (Cohen M2). Lack of Government funding against a biological attack is also evidence that the United States is not taking the threat of bioterrorism seriously. Mohammad N. Akhter, who is the executive director of the American Public Health Association, was quoted as saying that he â€Å"barely had the budget to deal adequately with a severe outbreak of the flu, let alone contain a smallpox epidemic† (A23).
