Pull production is the fundamental way and means to achieve production status of JIT, JIT production status is the highest goal of pull production. It can be said, JIT achieved, then lean production has been largely achieved. Heaven management consulting firm found that the back pull-production to achieve, the process of production time there are inconsistencies. Such a pull production, due to the time gap between each step of the production will inevitably lead to the production unit in Virtual Group unreasonable parts inventory, personnel work is not balanced, unbalanced load equipment, etc. The purpose of lean production can not achieve perfect. Pull production presented on the production of parts variety and quantity required. However, production problems in the necessary time pull production can not be solved. To be truly JIT-- "when necessary, according to the required number necessary for the production of products are only" the need to pull production based on the balance of production. This equalization is a pull-based, with the goal of JIT production organization equalization, we called JIT production equilibrium. JIT production balanced with Virtual Group production units each step in production time (including job changeover time and processing time) equalizer as the basic goal, to the entire virtual tact Group production unit is reduced to the higher goal of continuous improvement, conduct pursuit of perfection, in order to move towards the ideal state of lean production. 1. Virtual Group production units each step of production time equalization, from the following aspects: ① adjustment cast parts in batch group type, quantity and order, so that the difference between the process of production time is reduced. You can adjust the number of parts of investment priority batch group, followed by adjusting the different parts in the production process of a different order, again you can choose the type of parts; ② investment grant adjustment between groups. Part vote between two batches groups can be based on production time required exchange equalization, around two cast batch production sequence group can also be exchanged; ③ in Virtual Group production unit, introduce the concept of the work center, as shown below FIG. Appropriately integrated into the virtual set production units or production processes break down and match the appropriate device, similar to the following organizations that work in the center. The time difference between the production processes for the larger issues, the work center will play a better solution effect; ④ fictitious group in the current production unit, if no longer be balanced production time can be grouped with other virtual production unit common to be adjusted to achieve each Virtual Group production units in-house production time equalization. The above-mentioned aspects of production time equalization in: ①, ② can be seen as micro-level; ④ can be seen as the macro-level; ③ is between micro and macro. Thereby realizing a Virtual Group production units each step of production time equalization, JIT production will achieve a balanced (Of course, the practice is not easy). When such a production organization the status of a non-mass-produced at a high level type of "quasi-pipeline" will render out. 2, reduce tact Virtual Group production unit is to pursue a higher level of lean production. Under the premise of stable investment and grant the group, make the following adjustments can be reduced to a set of virtual production units in each step of production time, it reduces the tact of the unit (Here are some ways Tianxingjian management consulting firm Later it would be best to give priority to the past, and each time the production method should be carried out into the virtual set production units equalization). First, the current investment and grant appropriate to reduce the number of parts of the group; secondly, the current batch of group investment, appropriate to reduce the variety of parts, or make parts variety and quantity of adjustment and other investment grant groups; again, to adjust production units of Virtual Group in unit production time equalizer into the premise, in order to reduce unit production time of each process for the purpose. In short, the Organization of Virtual Group production units in each step of the production time equalizer, continue to lower unit beat pull production, it is possible to achieve the continuous improvement of JIT. This is the perfect lean production. Heaven management consulting firm Mr. Zeng 4007776907 Original link: www.leanchina.cn/jyscglnews/879.html
