分包可以是克服产能短缺和工作量平衡的重要手段，特别是在以多品种、高需求变化和车间配置为特点的按订单生产的公司中。但缺乏适合这种情况的简单而强大的分包规则。现有的少数规则是针对单一工作中心车间制定的，忽略了实际的分包交货时间，这意味着一些分包工作注定会迟到。本研究使用工作负载控制理论来随着时间的推移匹配所需容量和可用容量，提出四个新规则来解决这些缺点。使用装配车间模拟模型将新规则与四个现有规则进行比较，其中最终的装配产品由几个子装配体组成，这些子装配体要么流经内部车间，要么被分包。最好的新规则稳定了工作中心前面的直接负载排队，并与现有规则相比显着提高了性能。例如，当工作负载超过容量 10% 时，迟到百分比可以降低 50%。通过检查工作负载随时间的变化情况，我们发现改进来自于有选择地分包子组件，否则会导致过载，从而消除工作负载的峰值。
Subcontracting can be an important means of overcoming capacity shortages and of workload balancing, especially in make-to-order companies characterized by high variety, high demand variation and a job shop configuration. But there is a lack of simple, yet powerful subcontracting rules suitable for such contexts. The few existing rules were developed for single work center shops and neglect the actual subcontracting lead time, meaning some subcontracted jobs are destined to become tardy. This study uses Workload Control theory on matching required and available capacity over time to propose four new rules that address these shortcomings. The new rules are compared against four existing rules using an assembly job shop simulation model where the final, assembled product consists of several sub-assemblies that either flow through an internal job shop or are subcontracted. The best new rules stabilize the direct load queuing in front of a work center and significantly improve performance compared to the existing rules. For example, when the workload exceeds capacity by 10%, a 50% reduction in percentage tardy can be achieved. By examining how the workload behaves over time, we reveal that improvements come from selectively subcontracting the sub-assemblies that would otherwise cause overloads, thereby cutting off peaks in the workload.
