研究了一个延迟产品分化的生产系统,供应商在MTS系统的基础上为制造商提供半成品,当收到客户订单时,制造商再在MTO系统的基础上通过定制半成品来满足客户的需求.供应商生产半成品所花费的时间占总生产时间的比例将决定半成品适应客户需求的程度,制造商希望决定最佳的产品分化点和半成品缓冲区大小.利用拟生灭过程和矩阵几何解得到这个系统的性能指标,并且给出优化策略,通过系统仿真得到优化结果.%A production system of delayed product differentiation was studied. The supplier produced semi-finished items on the MTS basis for a manufacturer that would customize the items on a MTO basis after a customer order was placed. The proportion of total processing time undertaken by the supplier determined how suitable the semi-finished items met the customer demand. The manufacturer needed to determine the optimal point of differentiation and its optimal semi-finished goods buffer size. Various performance measures for this system were evaluated by using the quasi birth and death process and matrix geometric solution. A strategy was designed to optimize the system, and the optimization results were got by system simulation.
