| 中文摘要 |
| 制造系统的生产线由多个机器组合而成, 可以有多种表现形式, 各机器可以根据生产的实际情形改变生产率. 从系统可靠性的角度出发, 当机器以较低的生产率工作时可靠性较高. 这样, 提出一种能提高系统可靠性同时又能使各机器相互协调而提高生产线性能的策略就显得十分必要. 本文讨论了可变生产率的串行生产线模型, 对机器、缓冲区及生产线的运行状态进行了研究, 从机理上分析了生产线的运行状况, 得到了分析生产线性能指标的解析解: 稳态生产率, 并以稳态生产率为指标对这种生产线加以控制, 从而进行优化. |
| 英文摘要 |
| The production lines in a manufacturing system are composed of several machines and they can take many different forms with the various combinations of machines. In practice, the machines in a production line have variable processing rates which can be changed according to the practical operation states of the system. From the point of view of reliability, machines usually are fare more reliable when working at a relatively low production rate. Thus proposing a strategy,which can improve both the reliability and the performance of the systems becomes significant. This paper presents a transfer line model in which machines are of variable processing rates. The states of machines, the buffer and the line and the operation mechanism of the systems are studied. As a result, the steady state production rate of the system is obtained in an analytical form based on which the optimization control scheme of the line is discussed. |
