A fuzzy EPQ model with flexibility and reliability consideration and demand dependent unit production cost under a space constraint: A fuzzy geometric programming approach

In this paper, an Economic Production Quantity (EPQ) model is developed with flexibility and reliability consideration of production process and demand dependent unit production cost. The model has involved one storage space constraint. It is formulated in fuzzy environment introducing fuzziness in objective and constraint goals, coefficient and indexes of objective function and constraint. The model is solved by fuzzy geometric programming technique. The solution procedure is illustrated by numerical example.
