随机生产系统安全库存的ЛТ控制策略

Kanban Allocation of Just-In-Time Production System with Random Processing Times

本文研究了随机工件加工时间的生产系统在ЛТ（Ｊｕｓｔ－Ｉｎ一Ｔｉｍｅ）控制策略下的运行机制．基于文［１］所提出的看板控制生产系统的生产率与其马尔柯夫模型的状态空间相对应的理论．本文探讨了在ЛТ控制策略下生产系统的看板在安全库存受限的条件下的最优配置问题，并给出了工作站数目小于５的生产系统看板最优配置公式．

This paper describes the productkion process of Just- In-Time productionSystem with bandom processing times.Based on the result concluded in reference[1].that the mean throughput of kanban-controlled system can be measured througha surrogate size of state-spare of the Markov Chain.This paper discusses theproblem of the optimal Kanban allocation subjects to the constraint of fixed totalcards, and formulations of the optimal kanban allocation of systems with less thanfive workstations are given.
