An interactive graphic presentation for multiobjective linear programming Russell K.

A solution methodology proposed by Dror and Gass is employed. The pri- mary objective of the design process is to investigate the advantages of using interactive graphics in the presentation of alternative solutions and to direct the solution search. We ®nd several features useful, including three-dimensional perspective views, graph animation, interactive highlighting, and interactive detail inspection. Ó 2001 Elsevier Science Inc.

Introduction The task of locating a `best' solution in multiobjective linear programming MOLP) is not simply a matter of computation as it is with its single objective counterpart. Since no single solution is likely to optimize all objectives, either the optimizing solution of a single objective must be chosen giving up opti- mality on the other objectives) or a compromise solution is chosen which may Applied Mathematics and Computation 123 2001) 229±248 www.elsevier.com/locate/amc * Corresponding author.
