Two-Warehouse Partial Backlogging Inventory Model For Deteriorating Items With Ramp Type Demand

Abstract

This paper deals with two warehouse system for deteriorating items with ramp type demand. In this inventory model initially demand is considered to be linear function of time and it became constant after a finite time parameter. Holding cost assume to be constant in both warehouse. Partial backlogging is allowed. The proposed model is developing to minimize the total inventory cost which includes holding cost, backlogging cost, lost sale cost, and deterioration cost. Here three cases are taken into consideration depending on time where demand becomes constant. This is only an analytic approach towards the model.
