Customer-oriented management of manufacturing systems is crucial in service-oriented production and product service systems. This paper develops the selection of dispatching rules in combination with alternative process flow designs and demand mix, for a maintenance, repair and overhaul center (MRO) of turbo shaft engines, both for complete engines and engine modules. After an initial systematic screening of priority dispatching rules, the design of experiments and discrete-event simulation allows a quantitative analysis of the better rules for the alternative process flows with internal and service metrics. Next, the design of experiments with analysis of variance and the Taguchi approach enables a search for the optimal combination of process flow and dispatching rules. The consideration of extra costs for overdue work orders into the costing breakdown provides a quantitative evaluation of the optimum range of load for the facility. This facilitates the discussion of the significant trade-offs of cost, service, and flexibility in the production system and the operational management alternatives for decision-making.
在面向服务的生产和产品服务系统中，以客户为导向的制造系统管理至关重要。本文结合替代工艺流程设计和需求组合，为涡轮轴发动机的维修、修理和大修中心（MRO）制定了调度规则的选择方案，涵盖完整发动机和发动机模块。在对优先调度规则进行初步系统筛选后，实验设计和离散事件模拟允许使用内部和服务指标对替代工艺流程的更好规则进行定量分析。接下来，通过方差分析和田口方法进行实验设计，能够寻找工艺流程和调度规则的最佳组合。将逾期工单的额外成本纳入成本细分，可对设施的最佳负荷范围进行定量评估。这有助于讨论生产系统中成本、服务和灵活性之间的重大权衡以及用于决策的运营管理替代方案。
