Abstract: This paper is concerned with a loading schedule of manufacturing orders in a material requirement planning (MRP) environment. In an environment in which production capacity and/or job due date is tight, ordinary loading work has become complicated in order to attain the management goals. So a multiple objective model, which is divided into two loading phases under a hierarchical procedure, is proposed to support the loading work. A prototype loading system is developed using MP (mathematical programming) logic. KB (knowledge-based) approaches are also discussed for practical problems and the features of the two systems are compared.
