Abstract

In this paper, we have described an inventory model for a deteriorating item having preservation facility with trade credit policy. The demand for this inventory model is ramp type. Shortages are allowed due to the waiting time for the arrival of next lot. In this paper, we have described two inventory models due to ramp type demand. We have solved these two inventory models by using a separate numerical example. We have supplied concavity of the objective function for each model (winner case). Finally, we performed sensitivity analysis for each model and made a conclusion accordingly.
