A declarative approach to building decision support system for project management

Paweł Sitek, Jarosław Wikarek

Abstract


Project management is usually characterized by many types of constraints, which make this unstructured and difficult to solve. Traditional mathematical programming approaches are deficient because their representation of constraints is artificial (using 0-1 variables). Unlike traditional approaches, constraint logic programming (CLP) provides for a natural representation of heterogeneous constraints. In this paper we propose a declarative framework for decision support system (DSS) for project management implemented by CLP and relational SQL database.
