Abstract
In singleperiod inventory models neither excess demand nor excess inventory can be carried forward to the next period In stochastic multiperiod models an order is placed at some point in time during the cycle and leadtime is considered to be either constant or random Leadtime demand however is assumed to be probabilistic At the time an order is placed the amount of inventory which will be on hand when replenishment arrives is unknown In this paper we propose a variation of these models to determine the optimal economic order quantity Shipments arrive according to a Poisson process The status of the inventory becomes known at the time of the arrival of the shipment and the selection of order quantity is made at that time However the arrival time of future shipments is uncertain It is also demonstrated that traditional single and multiperiod inventory models can be obtained as special cases of the proposed model
