The main purpose of this paper is to determine the value of economic order quantity (EOQ) with two types of imperfect items, defective and reworked ones, under 100% inspection. Where defective items are treated as scraps and reworked ones will be sent back to supplier to get repaired. A mathematical model is built on the jo in t d ist ribut ion o f defective and reworked un its which fo llow a ...

This paper considers the basic economic order quantity (EOQ) model when all parameters, such as the demand rate, the ordering cost, and the inventory holding cost, are uncertain, and furthermore, their probability information is also unknown. To address the uncertainty, we adopt a robustness-based approach. In this approach, each unknown parameter is described as a continuous value restricted t...

We consider a continuous-review inventory model for a retailer who faces deterministic demand but whose supplier is unreliable. The supplier experiences “wet” and “dry” (operational and disrupted) periods whose durations are exponentially distributed. The retailer follows an EOQ-like policy during wet periods but may not place orders during dry periods; any demands occurring during dry periods ...

Determining the economic lot size has always represented one of the most important issues in production planning. This problem has long attracted the attention of researchers, and several models have been developed to meet requirements at minimum cost. In this paper we explore and discuss the evolution of these models during one hundred years of history, starting from the basic model developed ...

Abstract—In this paper, Economic Order Quantity (EOQ) based model for non-instantaneous Weibull distribution deteriorating items with power demand pattern is presented. In this model, the holding cost per unit of the item per unit time is assumed to be an increasing linear function of time spent in storage. Here the retailer is allowed a trade-credit offer by the supplier to buy more items. Als...
