An Inventory Model with Time Dependent Demand Under Inflation and Trade Credits

The traditional inventory model assumes that a retailer accepts the offer of delay in payments since he does not have the capital with him. Even when he has to make the payments at the end of credit limit, he takes a loan to pay off the supplier. The model focuses on commodities having quadratic demand with trade credit policies. The commodities considered in this model are perishable stock whose deterioration starts immediately as soon as you store the items. We have considered all the factors which one retailer must kept in mind deciding his inventory level, the concept of inflation and time value of money is also considered.

Two warehouse inventory model with stock-level dependent demand rate and time varying holding cost under shortages

The purpose of this article is to evaluate the value of integrating tactical warehouse and inventory decisions. Therefore, a global warehouse and inventory model is presented and solved. We have considered two separate warehouses, one is an own warehouse (OW) of finite dimension and other a rented warehouse (RW), for an infinite planning horizon. Model focuses on stock-level dependent demand rate and a time dependent holding cost. We considered holding cost is an increasing function of time. In addition, we allow for shortages and complete backlogging. A numerical example and sensitivity analysis on some parameters are implemented to illustrate the model.
