　　Automation is another pillar

　　Another pillar of lean production is automation. In order to achieve the goal of JIT production, equipment support is an essential part of the. TPM (total productive maintenance) is the cornerstone of support for these second pillars. TPM is a full participation in the management activities, although the core content is to the production facilities of self preservation, but in the implementation but influenced by various, including team collaboration between the various departments and work with the sense of service, staff morale, leadership layer resolutions on many factors. So enterprises in the implementation of should be fully prepared to create an atmosphere and to build the soft environment, including incentive mechanism set, implementation organization set up, the model line (the machine) first, supreme leader's determination. An army marches on its stomach., only to make full preparations, TPM work to achieve the desired effect.

　　To improve the equipment management, must through people and equipment to improve the quality, we must establish clear and higher goal must be advanced and reasonable method completely rule out the possibility of equipment and associated with the device of adverse factors, in order to pursue the maximum equipment efficiency, so as to achieve improve business performance and create a survival value of the enterprise. The implementation of TPM from the three elements up and down time:

　　Improve work skills. Regardless of the operator or equipment engineer to efforts to improve job skills, no good job skills, full participation will be empty talk.

　　Improve mental outlook. Mental outlook is good to form a good team, jointly promote the common improvement.

　　Improve the operating environment. Through 5S and other activities, so that the operating environment is good, on the one hand can improve the working interest and efficiency, on the other hand, can avoid some unnecessary equipment accident. The site clean, materials, tools, such as the other parts of the display, but also to set the time to adjust the time to shorten.

　　TPM group activities is to support the main pillars of TPM, the TPM group independent activities are preferably incorporated into the framework of organization system, its main activities and objectives is four "no", namely: no waste, no fault, no accident, no error, is characterized with full participation, the previously done by a few things into the conscious action of all the staff. Group activities at all stages are focused on, TPM implementation of the initial stage, to clean, training based. Maintenance operations in the middle of the main, the latter part of the meeting, inspection and self maintenance. The objectives of the group activities to be consistent with the company's goals, it is required to complete the company's objectives into each employee's needs. This point can do a good job, mainly to see management ideas.

　　TPM maintenance become the enterprise essential and extremely important part, maintenance downtime has become indispensable in the daily working plan table a and maintenance is no longer the a job without benefit. In some cases, maintenance can be considered as part of the manufacturing process, rather than simply following the failure of the assembly line, the aim is to minimize the emergency and unplanned maintenance.

　　Throughout the JIT production, is committed to the elimination of waste, the removal of all the activities do not add value. But in a series of production activities, it is often the bottleneck phenomenon, hinder the normal production rhythm, forming a series of waste.

　　Unbalanced phenomenon caused by many reasons, summed up mainly is: product specifications; operator proficiency on the job changes; site layout changes; raw materials, tooling and equipment operators of the production line balance effect.

　　In response to the above several reasons and need to related personnel to go to the production line operation method, operation, operation process of using effective measure method for a series of research and analysis, find out the root cause and factors related to optimization, to make them better. Improved methods are generally as follows:

　　First, the bottleneck process should be considered to improve the operation. Job improvement method, can refer to the analysis of the process of improvement methods and action analysis, tooling automation and other IE methods and means.

　　Share the work content of the bottleneck process to other processes.

　　Increase the staff, as long as the balance rate increased, the per capita output is equal to increase, the unit product cost also decreased.

　　With the relevant procedures, re arrangement of the production process.

　　The process of decomposing the working time is shorter, and the process is arranged in other processes.

　　JIT production has changed the traditional drive type production system, using a more excellent pull type production system. By order to determine the number of production, breaking the original plan mode, to the last process issued a production plan, other processes based on its plan to determine its output. From the month plan refinement to the weekly plan, day plan. The utility model has the advantages of production activities is determined by the customer demand of, in the production, each production process are determined by the needs of a production process, which does not produce additional products, so that you can eliminate overproduction generated excess inventory.

　　Pull production that does not demand the production is meaningless; pull production have direction, were more likely to meet customer demand, improve the production is to increase the value; through the level of a pull can make the process orderly smoothly, avoid the waste.

　　This mode of production to the production management requirements greatly increased, the supply of materials and change the time conversion requirements of accurate and detailed. Plan be accurate to the minute and second. To calculate the specific time to change the type of production, do a good job of external and internal type of preparation. In view of the changing operation, we should set up the work instructions to guide the operation of the exchange operator.
