Sequencing in Flexible Assembly Systems with Blocking

柔性化生产线的重要配置 制造系统由几个串联的装配站组成。 通常，每种产品类型以相同的方式流过这些站。 秩序 然而，每种类型可能具有不同的处理时间。 一些 高级生产线有能力跳过站时，工作需要 没有处理他们。 此外，可以阻止作业在 如果前一项工作仍在进行，则为机器。 这是 通常被称为“阻塞”，并且是 现代化的即时生产战略。 如果时间太长 在阻塞中花费，总线路吞吐量将严重降低。 缓解阻塞的旧方法是在 组装站，以吸收处理时间的差异。 但是，在这方面， 现代制造方法高度重视减少加工 过程库存。 因此，找到一个最佳的顺序， 不同的产品类型对于最大化生产线至关重要， 吞吐量

An important production line configuration used in flexible manufacturing systems consists of several assembly stations in series. Usually, each product type flows through these stations in the same order. Each type, however, may have different processing times. Some advanced lines have the ability to skip stations when the jobs require no processing at them. Also, a job can be kept from being processed on a machine if the preceding job is still being worked upon. This is commonly known as "blocking" and is a subject of prime interest for contemporary, just-in-time manufacturing strategies. If too much time is spent in blocking, total line throughput will be severely degraded. The old approach to ease blocking has been to place buffers between assembly stations to absorb differences in processing times. However, modern manufacturing methods place high priority on reducing work-in process inventory. Thus, finding an optimal order in which to process the different product types becomes critical for maximizing line throughput.
