TL;DR: A continuous review inventory model over a finite-planning horizon with deterministic varying demand and constant deterioration rate allows for shortages, which are partially backlogged at a rate which varies exponentially with time.

TL;DR: In this paper, the authors generalize the work of Wee and consider a model where the demand rate is a convex decreasing function of the selling price and the backlogging rate was a time-dependent function, which ensures that the rate of backlogged demand increases as the waiting time to the following replenishment point decreases.

TL;DR: This work is motivated by Soni and Shah's (2008) paper extending their model to allow for a non-zero ending-inventory, a profit-maximization objective, a limited inventory capacity and deteriorating items with a constant deterioration rate.

TL;DR: An inventory system where demand is satisfied by recovered and new purchased items is studied, and a simple formula that determines the optimal inventory level of recoverable (used) items is developed to start the inspection and recovery processes and the economic order quantity for procurement.

TL;DR: In this paper, an economic production quantity (EPQ) model was proposed for deteriorating items in a supply chain with both up-stream and down-stream trade credit financing. And the optimal solution not only exists but also is unique.
