Buyer - vendor fuzzy inventory model having time varying holding cost

In the present study, a Fuzzy inventory model having time dependent holding cost and changeable lead time over a time horizon is proposed. Latest Technology brought a drastic change in demand and supply chain management due which stimedependent holding cost is being necessary to be considered. We explore the Cost inventory system to incorporate two parameters. The two parameters i.e. Lead time and cycle time has been fuzzified using triangular fuzzy parameters. Graded mean integration method, Signed distance method and Centroid method are used to defuzzify the total cost. The main objective of the paper is to minimize the total cost per unit time in an inventory system.
