İzmirde Kurulu Bir Plastik İşletmesinde Karar Vericinin Optimal Hedeflere Odaklanmasında Toplamsal Model Tabanlı Bulanık Hedef Programlama (An Additive Model Based Fuzzy Goal Programming Allows Decision Makers to Focus On Optimal Goals in A Plastic Factory Which Is Established in Izmir)

Abstract

As known; goal programming, which is a type of multi-objective programming that its priority is satisfaction and based on optimization, allows decision maker to design an optimal system. Hence; a solution set provides simultaneous satisfactory is determined. Fuzzy goal programming model is analyzed in two different forms with respect to objective preemptive priority structure. In the first form, an importance level of preferences is specified quantitatively. In the second form, preference priority is added to model as linguistic information.In fuzzy goal programming; additive model which is adapted to mentioned two forms is developed by Tiwari, Dharmar and Rao (1987). Goal programming based on more satisfaction instead of optimization. Thus, using of fuzzy logic in this area is appealing. Goal programming approaches based on fuzzy logic is developed by the time of progress and every approach is aimed at getting better models. A model that allows preemptive priority in fuzzy goal programming in order to reach maximum membership and makes its solution to one structural problem is developed by Chen and Tsai (2001). Additive model which is proposed by Chen and Tsai allows for making desired success of level for every fuzzy goal by a decision maker. Thus, relative importance of these goals is stated clearly. In this paper, additive model used in fuzzy goal programming applied to plastic factory which is established in Izmir. The relationship between goals of production planning chief and model outputs is evaluated and presented.
