CAPACITATED MATERIALS REQUIREMENTS PLANNING AND ITS APPLICATION IN THE PROCESS INDUSTRIES
针对流程工业中传统物料需求计划（MRP）的不足，本文介绍了Welch's公司开发的两级电子表格方法，用于整合产能规划，并处理厂间转移、特殊加工和产品配方等物流问题。
Although material requirement planning (MRP) procedures have long been an accepted practice, these systems suffer from shortcomings that limit their usefulness for firms in the process industries. This paper describes a two-level, spreadsheet-based procedure developed at Welch’s, the largest processor of Concord and Niagara grapes, to perform integrated capacity planning. In addition to contending with capacity limitations, Welch’s, like many companies in the process industries, must consider the logistics of inter-plant transfers, special processing requirements, as well as proprietary product recipes when designing an MRP system.
