2. Multiobjective fuzzy linear programming problems with fuzzy decision variables

Author

Stanciulescu, C., Fortemps, Ph., Installe, M., and Wertz, V.

Subjects
Linear programming -- Analysis, Multiple criteria decision making -- Methods, Business, Business, general, Business, international
Abstract

A mutliobjective decision-making process is modeled by a multiobjective fuzzy linear programming problem. A method using fuzzy decision variables is proposed with a joint membership function instead of crisp decision variables.

4. Using metaheuristics for solving a production scheduling problem in a chemical firm: a case study

Author

Fortemps, Ph., Ost, Ch., Pirlot, M., Teghem, J., and Tuyttens, D.

Subjects
Scheduling (Management) -- Models, Production control -- Models, Chemical plants -- Production management, Business, Business, international, Engineering and manufacturing industries
Abstract

A method is developed for scheduling production in a chemical plant. The method is divided into two stages, namely, the assignment of jobs to equipments followed by the optimization of the order of jobs using simulated annealing or tabu metaheuristics. It is shown that the method provides optimal schedules for job-shops while its flexibility allows its application in various job-shop operations.
