本文试图应用运筹学理论解决连续性生产行业中生产计划和调度的优化问题。文章以上海市煤气公司为对象,采用了多层次计划的原则,针对公司的计划问题建立了一个线性成本模型。此模型考虑了能源的使用,反映了社会效益方面的决策标准。同时还相应建立了一个计算机软件包。针对厂级调度问题,我们根据运筹学的理论,提出了可行区域的概念,强调了调度中的一些关键因素,并根据不同煤气厂,分别设计了一套人工调度程序供调度员使用。该调度程序考虑了工艺和经济方面的因素。另外还建立了一个计算机辅助调度程序,以供今后有条件时使用。 This paper attempts to apply operational research theory to solve the optimization problem of production planning and scheduling in the continuous production industry. Taking the Shanghai Gas Company as an example, the article adopts the principle of multi-level planning and establishes a linear cost model for the planning of the company. This model considers the use of energy and reflects the decision-making criteria for social benefits. At the same time also set up a corresponding computer software package. According to operations scheduling theory, we propose the concept of feasible region, emphasize some key factors in scheduling and design a set of manual dispatcher for dispatchers according to different gas plants. The scheduler takes into account technological and economic aspects. A computer-assisted scheduling program has also been established for future use when conditions warrant.
