Since resource selection in job shop scheduling directly influences the qualities and due dates of produc ts and production cost, it is indispensable to take resource selection into acco unt during job shop scheduling. By analyzing the relative characteristics of res ources, an approach of fuzzy decision is proposed for resource selection. Finall y, issues in the application of the approach are discussed.展开更多
文章提出了2种新的单件装配生产过程的动态调度规则——LFT/RPS/CP规则和ELFT规则。构建这2种规则时,考虑了3个因素:工序的最晚完成时间、工序所在路径上的剩余工序数和工序是否在关键路径上。对这3个因素采取不同的组织方法从而得到了...文章提出了2种新的单件装配生产过程的动态调度规则——LFT/RPS/CP规则和ELFT规则。构建这2种规则时,考虑了3个因素:工序的最晚完成时间、工序所在路径上的剩余工序数和工序是否在关键路径上。对这3个因素采取不同的组织方法从而得到了2种动态调度规则。为了验证这2种调度规则的有效性,基于Visual Studio 2003使用C++语言开发了单件装配生产动态调度仿真程序。数值试验的结果表明,这2种规则在减少拖期产品数和减少总拖期时间方面具有很好的表现。展开更多
