Fuzzy Inventory Model for Power Demand Pattern with Inlation, Shortages under Partially Backlogging

Wasim Akram Mandal, Sahidul Islam

Abstract: In this paper fuzzy inventory model for non deteriorating item with power demand pattern, shortage under partially backlogged, and inflation is formulated and solved. Fixed cost, shortages cost, holding cost, opportunity cost are the costs function considered in this model. Fuzziness is applying by allowing the cost components (holding cost, shortage cost, etc) and inflation. In fuzzy environment it considered all required parameter to be pentagonal fuzzy numbers. The purpose of the model is to minimize total cost function.
