Development and performance evaluation of "heijunka" production and inventory control system in supply chain management

看板系统已被认为是控制复杂的生产和库存系统的优秀工具。平仓卡的意思是平滑生产订单和零件补货数量。本研究针对一个复杂的多阶段多产品生产与库存系统，研究其控制方法。本研究回顾了与生产平滑相关的生产计划与控制系统的研究现状。在此基础上，提出了一种基于黑珠卡的生产与库存控制系统，给出了系统优化的有效算法，并与传统的看板和MRP系统进行了比较，评价了基于黑珠卡的供应链生产订单系统的性能。结果表明，局部优化的生产平稳订单系统作为供应链中的生产和库存控制系统是非常有效的。

Kanban system has been known to be a superior tool to control complex production and inventory systems based on “heijunka”. The heijunka means smoothing the production order and part replenishment quantities. In this research, heijunka methods to control a complex multi-stage multi-product production and inventory system are investigated. This research reviews past researches of production planning and control systems concerned with production smoothing. Next the research develops a heijunka production and inventory control system, presents an efficient algorithm to optimize the system, and then evaluates the performance of the production order system based on heijunka in a supply chain as compared to the original kanban and MRP systems. It is concluded that the locally optimized production smoothing order system is quite effective as production and inventory control system in the supply chain.
