Workload control in dual-resource constrained flexible job shops: a simulation analysis
研究了将负荷控制(WLC)系统应用于双资源约束柔性作业车间(DRCFJS)的效果,发现资源分配规则对性能影响最大,实时响应机制和双因素控制能确保系统稳健运行。
Within the manufacturing environments of Dual-Resource Constrained Job Shop (DRCJS), where both workstations and workers face limitations, there is a category of scenarios known as Dual-Resource Constrained Flexible Job Shop (DRCFJS). In these common industrial manufacturing environments, operations can be carried out on any workstation and performed by any worker within a compatible set. While the DCRFJS environment has been extensively explored in the domain of production sequencing, it has not been thoroughly investigated within the framework of a Workload Control (WLC) system. The aim of this work is to study the performance of adapting the WLC system to DRCFJS environments. The findings emphasise the significant impact of the resource allocation rule during the release stage, surpassing the influence of dispatching rules and worker transfers between workstations. Additionally, the implementation of a real-time response mechanism, crucial to prevent workstations from idling due to the occupancy of assigned workers in other jobs currently in progress, is very important in modern manufacturing. Furthermore, our research demonstrates that concurrent control of these two critical factors ensures robust performance, regardless of the workload norm. This dual control approach facilitates the adaptation and effective operation of the WLC system in DRCFJS environments.
