In many inventory situations, purchasers are allowed an interest-free credit period to pay for the goods bought. Depending on the length of that period, the purchaser can earn interest on the sales of the inventory. In this paper, a deterministic economic order quantity (EOQ) inventory model is developed with time dependent demand under permissible delay in payment. The cost parameters are taken as...
In this paper, a multi-item economic order quantity (EOQ) model is considered in which the cost parameters are of fuzzy/hybrid nature under two types of resources — (a) resources as fuzzy quantities; (b) resources as fuzzy and fuzzy-random quantities. The unit cost depends on demand rate. The time horizon is taken to be infinite. We find the average cost for the model, which is a function of order...
