Hierarchical Production-planning Systems: Extensions and Modifications
本文扩展了Hax和Meal的层级生产计划方法，提出同时考虑功能与层级接口的模型，通过目标规划和分支定界法解决分解中的不可行问题，最小化积压。
This paper extends earlier hierarchical production-planning approaches initiated by Hax and Meal. The proposed model incorporates both functional and hierarchical interfaces simultaneously as encountered in practice, and assures feasibility and consistency among the decisions made at the different hierarchical levels of the firm. The problem of infeasibility which arises in disaggregating the aggregate production plan into detailed schedules is solved using goal programming at the product-family disaggregation level, and using branch and bound at the item-disaggregation level. The proposed approach minimizes backlogging regardless of the underlying cost structure of the problem at hand.
