Application of a fuzzy goal programming approach with different importance and priorities to aggregate production planning

This study presents an application of a fuzzy goal programming approach with different importance and priorities (FGPIP) developed by Chen and Tsai (2001) to aggregate production planning (APP), for the state-run enterprise of iron manufactures non-metallic and useful substances (Societe des bentonites d'Algerie-BENTAL-). The proposed model attempts to minimize total production and work force costs, carrying inventory costs and rates of changes in work force. The proposed model is solved by using LINGO computer package and getting optimal production plan. The proposed model yields an efficient compromise solution and the overall levels of Decision Making (DM) satisfaction with the multiple fuzzy goal values. Key words: Aggregate production planning; fuzzy goals programming; fuzzy linguistic; membership function
