Fuzzy multi-item economic production quantity model under space constraint: A geometric programming approach

摘要

In this study we have formulated an economic production quantity (EPQ) model with flexibility and reliability consideration of production process and demand dependent unit production cost with fuzzy parameters. The model is restricted with available limited storage space constraint. The inventory related costs, storage spaces and others parameters are taken here as triangular fuzzy numbers. The problem is solved by modified geometric programming method. Finally, the model is illustrated by numerical example.
