Research Initiation: Dynamic Planning and Scheduling for Production and Distribution Systems with Random Demand and Finite Capacity

9409344 Sox本研究的目标是建立具有随机需求和有限生产能力的多种产品的生产和配送库存动态计划和调度的数学模型和求解过程。动态意味着在滚动水平线上进行规划和调度。在一定时期内的每一阶段的生产能力，可以在一定时期内通过加班或加班费来增加。分销系统可以是单个成品仓库，也可以是具有中央仓库和多个不同零售商的两层系统。使用考虑季节性和非平稳的一般分布。该研究旨在制定基准，以评估在解决方案的质量和计算解决方案的时间方面开发的算法的性能。本研究开发的模型和算法将提供一种方法来整合和集中生产和分配系统的计划和调度。由此产生的工具也将提供一种评估这种规划系统价值的手段。此外，所开发的计划和调度方法可以通过平衡负载和混合的变化来补充准时制（JIT）控制。

9409344 Sox The objectives of this research are to develop mathematical models and solution procedures for dynamically planning and scheduling manufacturing and distribution inventories of multiple products with random demand and finite production capacity. Dynamic implies the planning and scheduling are done in rolling horizon. The production capacity at each stage in a given time period may be augmented in a given time period with overtime or additional shift. The distribution system may be a single finished goods warehouse or a two level system with a central warehouse and multiple, nonidentical retailers. General distributions that account for seasonality and are non-stationary are used. The research seeks to develop benchmarks for evaluating the performance of the developed algorithms both in the quality of the solutions and the time to compute a solution. The models and algorithms developed in this research will offer a methodology to integrate and centralize the planning and scheduling of production and distribution systems. The resulting tools will also provide a means to assess the value of such a planning system. Furthermore, the developed planning and scheduling methodology can supplement just-in-time (JIT) control by leveling out variation in load and mix.
