Classification and object-oriented frame representation of constraints in FMS scheduling
Ming Dong, Jianzhong Cha, Jinmin Wang, E Mingcheng, Jiexiao Zhang · 2002
In this paper, the constraints in FMS scheduling are classified and an object-oriented frame language is used to represent the different types of constraints. This language can describe numerical and symbolic constraints, and the deep constraint semantics can be obtained from the attribute and object constraint network. This deep constraint semantics will help the problem solving process of FMS scheduling.
