JIT准时生产的核心思想--新西兰essay代写范文

新西兰essay代写范文:“JIT准时生产的核心思想”，这篇论文主要描述的是JIT准时生产的方法在全世界的汽车制造企业中广泛使用着，这种JIT的方法最早源于丰田公司在应对能源危机时所使用，因为以往所使用的总动员生产方式导致资源浪费的弊端太过明显，使得JIT这种精益生产、降低库存的生产方式符合了各大汽车制造商的需求。

Before JIT method advocated by the world automobile production enterprises,including the Toyota Corporation are taking Ford style "general mobilization mode of production", namely the half time of personnel and equipment,pipeline waiting for parts, the other half time to part a, all the staff of general mobilization, emergency products. This resulted in the production process of the logistics of unreasonable phenomenon, especially in the overstock and shortage for the characteristics,production line or not boot, or the boot after the mass production, this model leads to a serious waste of resources. Toyota Corporation JIT is taken by the multi variety and small batch, short period of production, to achieve the elimination of inventory, optimization of production logistics, reduce the waste of purpose.

The basic idea of JIT production mode is the "only when needed, according to the need of the amount, produce the desired product", also is the pursuit of a non inventory, inventory to a minimum or production system. The basic idea of JIT is to plan and control of production andinventory management. Therefore, the JIT production mode is also known as "lean production".

JIT is the core of the pursuit of a non inventory production system, production system and inventory to a minimum. For the development of the "Kanban" "includes a series of specific methods, and gradually formed a set of unique production and operation system.

JIT takes just in time production as the starting point, first exposed to excessive production and other aspects of the waste, and then the equipment,personnel were eliminated, adjustment, reduce cost, simplify the program andimprove control objective. In the control technology in production site, the basic principle of JIT is at the right time, produce the correct number of parts or products, instant production. The traditional production process of step backward procedure for delivery,after the procedure according to the "Kanban" forward procedure pickup,Kanban system is just in time production control of core technology, but timeis not only the Kanban management.

One of the basic JIT is balanced production, the average manufacturingproducts, make the logistics in the operation, production line, factory between processes, between balance, equilibrium flow. In order to achieve the equalization, the monthly plan, plan in JIT, and adjustthe plan according to the demand.

JIT advocates the use of object specialization layout, to reduce the queuing time, transport time and preparation time, object specialization layout based on plant level, so that each batch of workpieces can flow smoothly in the operating rooms and workshops, decrease through ; The micro object specialization layout and work center layout in the pipeline and work center level, can be reduced by time.

JIT can make rational use of production resources, including labor flexibility and flexible equipment. When the market demand fluctuations, labor resources also make corresponding adjustment. If the demand increase, through appropriate adjustment with a variety of skillsof the operator to complete; When the demand is low, can be used to reduce the production schedules,dismiss temporary workers, distributing the redundant operators to maintain and repair equipment. This is the meaning of labor flexibility. The equipment flexibility refers to considering the processingproblem in the design of products, the development of multiple function equipment.

JIT emphasizes the total quality management, the target is to eliminate the unqualified products. To eliminate the root causes of nonconforming product, and try to solve the problem, the JIT also contains many factors conducive to improve the quality of the parts, such as small batch, quickly moved to the next working procedure,quality problems can be found as soon as possible.

JIT is driven by order, through the Kanban, by stimulating the supply,production, marketing closely together, so that the material reserves,inventory and WIP cost is greatly reduced, improving the production efficiency.

JIT is an ideal mode of production, there are two reasons for this.The main characteristic and the operation principle of JIT. It is one of the highest standards, a limit, is the "zero inventory". The second is because it provides a continuous improvement approach, namely,reduce inventory exposure problem - solve problem - reduce inventory ? ? ?this is an infinite loop of the process.

The basic idea of JIT operation is required for the supply side, namelyaccording to the request, in accordance with the requirements ofthe demand of varieties and specifications, quality, quantity, time, place, willthe goods to designated locations. Not earlier, not later, not much, not less, and to ensure that no defective goods deliver goods.

Therefore, the control method JIT inventory and traditional inventory is different, the inventory is useless, is a waste of resources. The traditional idea thinks, inventory can buffer function tooperate. Therefore, inventory management is always thinking of how to provide a bufferbased on minimum cost; and believe in JIT operation management is thinking about how we can eliminate the dependence of inventory. They also believe that to hold inventory will put some obvious problems in the process of the cover up, such as: order lead time is too long, the operation is not balanced, equipment failure, material quality is not good, the supplier is not reliable, large amount of paperwork and change too casual etc. To solve this problem cannot depend on holding lots of inventory, with realsignificance is to solve the problem in the clear after it. The main characteristics of lean production JIT performance:

(1) quality - looking, correct and solve problems;

(2) flexible, small batch, a stream;

(3) time to market, the development time is reduced to the minimum;

(4) product diversification -- shortened product life cycle, reduce the scaleeffect;

(5) improve productivity, efficiency, reduce waste;

(6) adaptability -- standard size assembly, coordin tion and cooperation;

(7) learning, continuous improvement.
