A Note on Dave's Inventory Model for Deteriorating Items

In this paper an attempt has been made to generalise Dave's results on an inventory model for deteriorating items. He has derived the results for optimal order level and lot size, considering a deterministic constant demand throughout the scheduling period. Here, a variable known demand is taken to show that the optimality conditions for the optimal initial stock do not depend on the nature of the demand. A numerical example is used to illustrate the analysis.
