提出了一个同时考虑承诺交货时间可靠性和需求对交货时间是敏感的交货时间和产能决策模型.在此基础上,结合两类(人工作业和自动化)订单式生产系统的特点,运用排队理论分别建立M/M/1企业型和M/D/1企业型模型.模型的解显示:最优的产能扩张与承诺交货时间存在着类似于耐克函数的关系;最优的产能扩张与承诺交货时间受承诺交货时间可靠性限制.通过对两类模型的敏感性分析给出了一些管理启示.最后用一个算例说明了模型的应用.
Proposed a delivery time and capacity decision model that considers both the reliability of the delivery time and the delivery time and the demand delivery time.According to the characteristics of two kinds of order-type production system (manual operation and automation) Using queuing theory to establish M / M / 1 enterprise model and M / D / 1 enterprise model respectively, the solution of the model shows that there exists a relationship similar to the Nike function between the optimal capacity expansion and the promised delivery time. Expansion and Commitment The delivery time is limited by the reliability of the promised delivery time. Some management implications are given through the sensitivity analysis of the two models. Finally, an example is given to illustrate the application of the model.
