A Fuzzy Goal Programming for Dynamic Cell Formation and Production Planning Problem Together with Pricing and Advertising Decisions

In this paper, an integrated mathematical model of the dynamic cell formation and production planning, considering the pricing and advertising decision, is proposed. this paper puts emphasis on the effect of demand aspects (e.g., pricing and advertising decisions) along with the supply aspects (e.g., reconfiguration, inventory, backorder, and outsourcing decisions) in the developed model. due to the imprecise and fuzzy nature of input data such as unit costs, capacities and processing times in practice, a fuzzy multi-objective programming model is proposed to determine the optimal demand and supply variables simultaneously. for this purpose, a fuzzy goal programming method is applied to solve the equivalent defuzzified multi-objective model. the objective functions are to maximize the total profit for firms and maximize the utilization rate of machine capacity. the proposed model and solution method are verified by a numerical example.
