Multi-Echelon Supply Chain Inventory Model for Deteriorating Items Under the Effect of Inflation and Preservation Technology

Abstract

In the present model we have developed multi-echelon supply chain model for deteriorating items with exponential time dependent demand and non-instantaneous deterioration. Preservation technology was implemented to control the deterioration of the manufacturer items which provide extra protection items. Entire study carried out under the impact of inflation. In the present study we consider the two suppliers involved in the supply chain for supplying raw materials to the manufacturer. The manufacturer produces a random proportion of deteriorating items which are reworked after daily production. Items sold out in lot to other markets after completing the rework process. Retailer sells finished items in various markets according to seasons. Numerical examples with optimal solution present the validity of the model. Finally, sensitivity analysis and graphical representation have been shown for the analysis.
