Research Initiation: Hierarchical Production Theory and Real Time Control

工业中的一个重要问题是协调生产过程 在多产品工厂，以尽量减少生产和 库存成本。 在这项研究工作中，计划是概括一个 先前开发的用于在这种工厂中调度生产的方法 (e.g.,造纸米尔斯）。 首先，一个经典的生产调度模型 有限期间的期末存货，以及累积或 生产总量。 然后，参数化方法 在每个时期内安排生产，以满足计划的目标， 期末存货和总产量，接收能力 限制考虑。 产品价格用作激励措施 以生产和作为偏离目标库存水平的惩罚。 该程序模拟选择特定产品的后果 在特定的时间段。 它产生良好的（不是最佳的）时间表 快速，因此可以交互使用。 时间表可以更改 真实的反映变化或不可预见的情况。 各种 数学方法将被用于改进产品排序， 时间段的选择，以及从一种产品到另一种产品的生产过渡 另

An important problem in industry is coordinating production processes in multi-product factories, so as to minimize the sum of production and inventory costs. In this research effort, the plan is to generalize a method previously developed for scheduling production in such plants (e.g., paper mills). First, a classical production model schedules end-of-period inventories for finite periods, as well as cumulative or aggregate quantities of production. Then, a parametric method schedules production within each period to meet the planned goals for end-of-period inventories and total production, taking capacity constraints into consideration. Product prices are used as incentives to produce and as penalties for deviating from target inventory levels. The program simulates the consequences of choosing specific products for specific time periods. It generates good (not optimum) schedules rapidly, and thus can be used interactively. Schedules can be changed in real time to reflect changing or unforeseen conditions. A variety of mathematical methods will be used to improve product sequencing, choice of time period, and transition of production from one product to another.
