Performance Analysis of a Multi-Item Production-Inventory System Under Alternative Policies
比较了多产品生产库存系统中两种信息收集与利用策略（先到先服务与最长队列）的绩效，推导了前者的封闭式绩效度量并为后者提出近似方法，通过仿真验证，探讨了集中信息价值与产品线广度的影响。
This paper explores the performance of a multi-item production-inventory system. We compare two alternative policies, representing different modes of collecting and utilizing information. We derive a closed-form measure of performance for one of them, the familiar first-come-first-served (FCFS) policy, and propose a comparable approximation for the other, the longest-queue (LQ) policy. These results are illustrated and tested through simulations. In this way we address several basic managerial issues: What is the value of centralized information in complex systems? How does the breadth of the product line affect performance?
