摘要: | 现今工厂在面对动态与不确定因素之制造环境下, 常受以下主要变动因素 或方案影响, 而必须重排整个排程: 1. 缺料 (Material shortage) 2. 紧急订单插入 (Rush order insert) 3. 机器故障 (Machine shutdown) 4. 订单变更 (Order changes) 5. 品质问题 (Quality issue) 6. 工程设计变更和试作 (ECO and Pilot run) 7. 生产进度超 前或落后 (Build ahead or backlog) 8. 新产品加入与旧产品结束 (New product phase in and End of Life product phase out) 9. 人员差勤异常 10. 瓶颈站漂移 (Bottleneck shift). 然而在执行重 排程时又会面临到重排程的时机及频率、是否执行重排程评估之标准、所 涵盖时程长度、 排程计划修正的方法、应变方案之拟订以及控制架构和 程序之设计等决策问题. 本研究问题主要在探讨以重排程因素为导向的 启发式重排程之方法, 并应用于电子厂流程线. 针对不同的变动因素, 单 项抑或多项同时发生, 而必须重排时, 可先将重排程因素变动处理状况予 以归类, 再考虑限制条件之设定, 选择适当的应变方案、排程方法与演算 法则, 配合人性化电脑排程系统(Human Oriented Scheduling System ;HOSS) 与现场监控系统 (Shop Floor Control System; SFC), 以发展一套有效可行能反应实际状况的动态及时生产重排程系统. Currently most of factories are under stochastic and uncertain manufacturing environment, which often affected by the following factors or alternatives induce to we have to reschedule the whole schedule: 1. Material shortage 2. Rush order insert 3. Machine shutdown 4. Order changes 5. Quality issue 6. ECO and Pilot run 7. Build ahead or backlog 8. New product phase in and End of Life product phase out 9. Operator leave abnormal 10. Bottleneck shift. When to perform the reschedule also will ecounter the timing & frequency of rescheduling、the length of cover horizon、the method of updatingschedule and to set the reactive alternatives...etc problems. In this research, we propose a heuristic rescheduling algorithm which oriented by reschedulingfactors, it can be applied to Electronic flow line. Focus on single or multiple factors occur simultaneously, when rescheduling is required. These rescheduling factors can be classified, and then to consider the constraints, try to combine HOSS (Human Oriented Scheduling System) and SFC (Shop Floor Control System) to develop a real-time and dynamic rescheduling system, which can to reflect manufacturing reality effeciently. |
