Production planning and scheduling is an area of research that has received much attention over the last two decades. It includes long-, medium-, and short-range planning. Productivity is low if these activities are not performed well. Three problems in this area will be investigated. One involves medium-range planning: enhancing algorithms that determine lot sizes and the scheduling of production operations and raw material acquisition. Better estimates of lead times are expected from this work. A second problem also involves medium-range planning: it takes account of uncertainty in multi-stage manufacturing systems. Better estimates of safety stock and safety time are expected. The third problem involves short-range planning: development of an algorithm for detailed scheduling of production operations, fast enough to deal efficiently and effectively with the stream of disruptions that make many detailed schedules obsolete almost as soon as they are created.

生产计划与调度是近二十年来备受关注的研究领域。它包括长期规划、中期规划和短期规划。如果这些活动没有很好地进行，生产率就会很低。将调查这一领域的三个问题。其中一个涉及中期计划：改进确定批量以及生产操作和原材料采购计划的算法。这项工作预计会对交货期做出更好的估计。第二个问题也涉及中期计划：它考虑了多阶段制造系统的不确定性。预计对安全库存和安全时间的估计会更好。第三个问题涉及短期计划：开发一种用于生产操作的详细调度的算法，该算法足够快，足以高效地处理源源不断的中断，这些中断使许多详细计划几乎一创建就过时了。
