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

9409344 SOX本研究的目标是为具有随机需求和有限生产能力的多种产品的制造和分销库存的动态计划和调度开发数学模型和求解程序。动态意味着计划和调度在滚动的水平中进行。给定时间段内每个阶段的生产能力可以在给定时间段内通过加班或加班来增加。配送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级系统。使用考虑季节性和非平稳的一般分布。这项研究旨在制定基准，以评估所开发算法在解的质量和计算解的时间方面的性能。本研究中开发的模型和算法将提供一种方法来集成和集中生产和配送系统的计划和调度。由此产生的工具还将提供一种手段来评估这种规划系统的价值。此外，开发的计划和调度方法可以通过平衡负荷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.
