The paper presents a concept and the outline of the implementation of a hybrid approach to modeling and solving constrained problems. Two environments of mathematical programming (MP) and logic programming (LP) were integrated. The strengths of integer programming (IP) and constraint logic programming (CLP), in which constraints are treated in a different(More)
The paper presents the concept and the outline of the implementation of a hybrid approach to supply chain optimization. In this approach, integration of two environments of integer programming (IP) and constrain logic programming (CLP) is proposed. The idea behind the new solution is to use the strengths of both environments, in which optimization(More)

This paper deals with declarative decision support framework for scheduling groups of orders. All orders in a group should be delivered at the same time after processing. The authors present a novel declarative approach to modeling and solving scheduling problems as a declarative decision support framework. The proposed framework makes it possible to ask(More)
