【正文】 to the changes in production of a product, set the two production lines, one is to meet the minimum volume of fixed production line, the other is part of the changes to meet changes in production , the traditional fixedline production equipment being used, and flexible production equipment or methods to be used as a cell changes in production order to pletely reduce costs, changes in line in Japan, panies often hire service workers to respond to dispatch the zero, no refund can be at any Manufacturing is a general trend: the production line getting shorter, more simple, less investment in equipment。 among fewer and fewer stocks, site utilization increasing。 production cycle is shorter and shorter, speed of deliveryfaster and faster。 all kinds of loss less and less, increasingly be seen, to achieve flexible manufacturing can greatly reduce production costs, and strengthen the petitiveness of enterprises.First, the characteristics of flexible productionFlexible means panies can change according to market demand, quick raising and lowering of production capacity, the ability to transform product production line capacity fixed, while the setting for the manufacture of specific products, which do not have production line is relative to the largescale production is difficult to change the rigid, the more flexibility and production generally have the following characteristics:Smaller production lineThe main features of flexible production can be summed up in one word, that is small, it has little a small number of production lines to work independently instead of a largescale production line, when the product demand to increase or decrease, can be easily copied or removed through a small production line to be the same time, with more than a small production line to replace the largescale production line for production of many varieties at the same time provide a more effective , the main method to achieve flexible production is small production from flexible production, the reduced factory production line should be the focus of the production line balancing point of view, the more the number of the more difficult to balance the production line, its efficiency is usually not longer lines, more the number also means that more of the products in the production line, which also bound to affect production efficiency and production the more the number of production line, the more chance of error, it will lead to more quality problems and the more production line setLowcost production of flexible production line is set the production line is set to spend millions to copy, remove or change is not so easy, the production loses its flexible.The flexible production of some plants to visit, you may find that their product line is very simple, some are even similar workshops in the way of production, not that kind of production is backward, for this phenomenon need to be flexible productionto look production line set up production lines in addition to the materials required to build simple, inexpensive, and requires material possible, versatile, easy to reuse change in the production line.Continuous change mode of productionFlexible production corresponding to rapid changes in market demand, the changing requirements of market demand, the production pany to make adjustments by the enterprise itself is not flexible production methods static, need to be improved or even create new flexible production methods to adapt to market actual situation of each enterprise is different, not a universal flexible production of flexible production enterprise, requires a bination of the production characteristics of the enterprise and market environment facing the actual situation in a creative way to establish methods for the production of the enterprise and continuous good site to improve the atmosphere on the implementation of flexible production enterprises is of great implementation of flexible production factory, production line equipment often is, many improvements from the hands of field staff. Second, the cell productionUnit production (Cell Manufacturing) is a product of small production set to a number of small production line to replace the largescale production line, and each production line can be independently a small largescale production line work, such a small production line is a production production is the most mon form of flexible of cell production is not only easy to copy and removed for quick changes in the corresponding output offers the possibility, the same time, several production units in place of a largescale production line, but also facilitate the production of many varieties at the same of requirements in the unit cell production workers must have received better training, to plete a variety of of production is due to work independently of each unit, each unit needs to use the full range of tools and test equipment, unit of the same capacity to replace a production line, may require higher to reduce the unit costs, in addition to make use of simple, inexpensive, and has a versatile material, but could be considered highvalue tools and testing equipment shared between two or more units.Changes in market demand for factory products, usually in a range, the fixed ponent and variable the implementation of flexible production facility, according to the actual situation, you can use existing production lines and production unit in the form of the bination will yield some of the existing fixedline production, some changes in unit lines to achieve extreme miniaturization, is the one mode of production.In one mode of production, the workers assembled a product (or product of a ponent) of all the product (or ponent) assembly processes less, and the yield is not significant, one mode of production because of its excellent flexibility in certain circumstances also mode of production but also production lines and stations, the workers at the station by mov
