Activity/Constraint: Object Modeller (ACOM). A Development Environment for LinearProgramming Based Decision Support Systems

摘要

The objective of this research project is to develop a prototype DSS which servesas an environment for conducting experiments with tailored for strategic and tactical production planning. This thesis describes the design and implementation of the Activity/Constraint-Object Modeller (ACOM). Two variants of the algebraic notation that is customarily used to denote (MI)LP models are presented. Three case studies are presented. The models deal with strategic logistics decisions and have been used as the basis of prototype planning supports systems. A simple procedure facilitates the formulation and interpretation of logical constraints to which the analogy with physical flows does not apply. It appeared that the modular arrangement of models that deal with logistics chains which consist of different types of actors coincides with the connections between the actors that exist in the problem domain.
