当计算机系统长时间运行之后,很多人或许会感觉到系统速度会越来越慢,硬盘剩余空间也越来越小了。特别是一些喜欢下载软件或欣赏视频的用户,常常会感觉到硬盘空间就像是被病毒侵蚀一样不知不觉就被消耗光了。 相似文献

This study considers serial production systems with exponential processing times. The systems are balanced, i.e. all resources have the same production rate capacity. Preceding the system there is a 'gate' set to regulate the flow of material into the system. A control strategy directs each resource when to work or stay idle. The trade-off is between throughput (TP) and work-in-process (WIP). G-MaxWIP is a production control strategy allowing resources, except for the gate, to work unconstrained. The gate 'shuts' once the system's WIP reaches a maximum allowable level. We study the properties of G-MaxWIP and compare it to 'simple pull' and CONWIP. Our main findings are: G-MaxWIP is superior to simple pull. For any simple pull system operating a fixed set of resources it is possible to find G-MaxWIP systems that operate the same resources with less WIP while maintaining the same (or higher) TP. G-MaxWIP is superior to CONWIP. For any CONWIP system operating a fixed set of resources it is possible to find G-MaxWIP systems that operate the same resources with less WIP while maintaining the same (or higher) TP. 相似文献

Certain types of organizations operate continuously and must allocate personnel over time to meet fluctuating, but cyclical, staff requirements. The optimal allocation of personnel in this situation is formulated as an integer linear programming problem, and the special structure of the formulation is exploited in order to develop an efficient solution algorithm which requires only hand calculations. The relationship between optimal solutions and flexibility in the original data is also considered. 相似文献
