We suggest a new inventory continuous time stochastic model for deteriorating items. We derive optimal operating characteristics of the expected cost per unit time under the assumption that demand in each replenishment cycle forms a regenerative process. We also present numerical examples. 2000 Mathematics Subject Classification. Primary 60K30, 60J10, 90B05.

This paper considers the impact of inflation on the EPQ model for deteriorating items subject to random machine breakdowns and fixed maintenance period. The demand rate is assumed to be a function of inflation and the demand increase due to inflation. The objective is to determine the optimal production uptime that minimizes the present value of expected total costs per unit time consisting of ...

Inventory models for deteriorating items of a supply chain is critical essence to the maritime industry. This study proposes real and economically efficient multicriteria inventory policy with nonlinear ramp functions permissible delay in payment under inflation, two conditions Shortages Followed by (SFI) (IFS) have been considered formulation models. Both consist ordering cost, unit deteriorat...

In this paper we develop an inventory model, to determine the optimal ordering quantities, for a set of two substitutable deteriorating items. In this inventory model the inventory level of both items depleted due to demands and deterioration and when an item is out of stock, its demands are partially fulfilled by the other item and all unsatisfied demand is lost. Each substituted item incurs a...
