面向大规模定制的虚拟产量分配方法及应用

分析成组生产环境中订单—产量分配问题的复杂性，提出一种基于累计平均合格率的虚拟产量分配方法，介绍在某自动订单跟踪系统中的实现和应用。实例表明：该方法既能虚拟地为各订单分配合适的相似半成品产量以利于订单跟踪，又能在客户订单分离点上，根据实际分离要求对各订单的虚拟产量分配结果进行综合以指导相似半成品的物理区分，可有力地改善成组生产中作业管理决策的科学性，可有效地避免由于盲目决策引起的一系列不良后果。

MASS CUSTOMIZATION ORIENTED APPROACH FOR VIRTUAL ALLOCATION OF THROUGHPUT AND ITS APPLICATION

Following the analysis of the complexity of the throughput-allocating issue in the group techndogy(GT)-based manufacturing processes,a virtual approach for through- put-allocation is proposed based on the concept of cumulative average turnoff ratio.The approach is then implemented in the Similar Semi-finished products(SFP)delivery planning module of an automatic order-tracing system.A case study illustrates that the module,on one hand,can virtually allocate reasonable similar SFP throughputs to every order in the GT-based manu- facturing processes to facilitate automatic order-tracing,on the other hand,can guide the division of a group of similar SFP throughputs into small sections according to the needs of dif- ferent orders at the customer-order decoupling points,which, therefore,can largely improve the rationality of the delivery plans and can effectively avoid the adverse consequences from unwise throughput-allocating decisions made by human dis- patchers,such as the supplementary production and the delay of the deliveries of some customer orders.
