Fuzzyfication of supplier–retailer inventory coordination with credit term for deteriorating item with time-quadratic demand and partial backlogging in all cycles

Abstract

Abstract A finite planning horizon supply chain model is discussed for materials substances such as metals, ceramics, or plastics manufactured which is deteriorating in nature. Parameter such as holding cost and all the other cost are fuzzyfied. Triangular fuzzy numbers are used for the fuzzyfication of parameters. Defuzzyfication of the model is done using total -integral value. We also have used Graded Mean Representation method to defuzzify the model. Later the comparison between the two defuzzyfied model is presented and conclusion is drawn.
