JIT最终装配计划中投产顺序的研究

The Research of Flexible Final-Assembly Scheduling Methods in a JIT Production System

针对 JIT的准时供货、减少在制品量和缩短调整时间等要求 ,分析了最终装配计划中比较实用的 3种投产顺序方法。对以最大延迟时间最短为目标的算法进行了证明 ,并分别介绍了以保持各种零部件的出现率不变为目标和使总的调整时间最短为目标的启发式投产顺序算法。

This paper analyses three flexible final-assembly scheduling methods in a JIT production system for supplying material just-in-time , lowing work-in-process inventory, reducing setup time. The sequencing algorithm for minimizing the maximum time of late jobs is proved, and the heuristic algorithms for keeping the rate of the use of the component and parts and minimizing the total setup time are discussed.
