MULTI‐OBJECTIVE PRODUCTION PLANNING MODEL FOR A GARMENT FACTORY

Production planning requires that consideration be given to the various aspirations of management, customers and workers. These multiple goals, however, tend to be conflicting in nature. A multiple goal model structure is formulated for a garment factory based on the objectives of the company including minimisation of lateness, maximisation of revenue, minimisation of production cost, and minimisation of overtime. The model was applied using real data obtained from the subject company and was run using the Sequential Linear Goal Programming (SLGP) algorithm implemented with the use of the MPSX package in an IBM computer. Sensitivity analysis was performed to give insights to the decision makers concerning trade‐offs that exist among the conflicting objectives.
