Manufacturers typically plan a production schedule on the basis of actual orders received together with orders that are forecasted for the next few weeks, on the assumption that there will be no new orders until the end of the planning horizon. A key issue is to determine a length for this planning horizon. A short planning horizon typically results in important future information being unavailable to the decision maker, and therefore schedules are more costly than if more information were available. On the other hand, forecasting demand and scheduling under a longer planning horizon is also costly and difficult to perform accurately. Therefore, a balance is required between these extremes. This proposal aims to study how the length of a planning horizon affects the quality of a schedule. Various scheduling environments will be considered, and methodologies developed for establishing a suitable length planning horizon that produces a schedule of the desired accuracy.

制造商通常会根据接收的实际订单以及未来几周预测的订单计划生产时间表，假设直到计划范围结束时才有新的订单。一个关键问题是确定该计划范围的长度。简短的计划范围通常会导致决策者无法获得重要的未来信息，因此时间表比有更多信息的时间更为昂贵。另一方面，在更长的计划范围内预测需求和调度也很昂贵且难以准确。因此，这些极端之间需要平衡。该建议旨在研究计划范围的长度如何影响时间表的质量。将考虑各种调度环境，并开发出用于建立适当长度计划范围的方法，从而产生所需准确性的时间表。
