Extensions of Pareto efficiency analysis to integer goal programming

This paper focuses on the design, development and implementation of new Par eto efficiency detection and restoration techniques for integer goal progra mming. The design of the algorithms and their implementation issues within (an otherwise continuous) goal programming system are detailed. The differe nces between continuous and integer goal programming regarding Pareto effic iency detection and restoration analysis are described. The integer Pareto efficiency techniques have been applied to a selection of problems from dif ferent industrial contexts in order to assess their computational performan ce. Finally, Pareto restoration and detection techniques are applied to an integer goal programming problem to illustrate the methodology. (C) 1999 El sevier Science Ltd. All rights reserved.
