企业资源优化问题的集成建模方法

提出了基于物料清单集成的集成建模方法，该方法是一种新的企业资源优化系统的核心技术。为了缩小企业资源优化系统模型的规模，根据物料在物料清单和工艺路线中的特性，将它们分为关键物料和非关键物料，通过一个物料清单集成过程，将非关键物料集成到关键物料中。求解由关键物料构成的规模缩小的模型后，再通过一个分解过程，得到所有物料的排产计划。

Aggregate modeling for enterprise resource optimization

An aggregate modeling method based on Bill of Material(BOM) aggregation was proposed,which played a key role in new Enterprise Resource Optimization System(EROS).In order to reduce the scale of EROS model,the production materials were divided into critical and non-critical materials according to the characteristics of the BOM and process routing.Through a BOM aggregation process,the non-critical materials were aggregated into the dummy ones.After solving the small scale model which was composed of critical materials and dummy materials,a decomposition process was used to achieve the necessary production scheduling information of the original materials.
