An inventory model with trade-credit policy and variable deterioration for fixed lifetime products

Abstract

The purpose of this study is two-fold. The first is to consider supplier's and retailer's trade-credit policy for fixed lifetime products and the second is to extend Mahata's 2012 model with time varying deterioration where Mahata (Expert Syst Appl 39(3):3537-3550, 2012) wrote exponential deterioration but actually he considered constant deterioration. We assume that the suppliers offer full trade-credit to retailers but retailers offer partial trade-credit to their customers. Some numerical examples along with graphical representations are given to illustrate the model.
