Waste management and reworking are very crucial issues in the cleaner production system. The adaptation of preservation mechanism inventory control is also a key aspect from an economic environmental point view. In current study, model for system modelled considering all these practical inflation. Deterioration process takes place model, market demand viewed sales team efforts selling price dep...

The risks on supply chain have increased continuously in recent years. One such risk for Hi-tech products is the result of rapid technological innovation which results in a significant decline in the component cost, the selling price and the demand (due to newer products introduction). The Hi-tech products include computers and communication consumer’s products. From a practical standpoint, a m...

In today’s competitive business situation, the supplier frequently offers his or her retailers a permissible delay period ( i.e. , trade credit) to stimulate sales. addition, capacity of any warehouse is limited in practice, thus retailer needs an additional rented (RW) store excess units when order quantity exceeds own (OW). Furthermore, with globalization marketing policy, may provide discoun...

Several researchers have recently derived formulae for economic order quantities (EOQs) with some variants without reference to the use of derivatives, neither for first-order necessary conditions nor for second-order sufficient conditions. In addition, this algebraic derivation immediately produces an individual formula for evaluating the minimum expected total annual cost. The purpose of this...

Many companies use time as a means of differentiating themselves in the marketplace. In many literatures, the controllable lead time is regarded as a decision variable and decomposed into several components, each having a crashing cost function for the respective reduced lead time. When an item is out of stock, the loyal, patient and captive customers will wait until the outstanding orders arri...

In practice the items received in a lot may contain defective items, and the screening process to eliminate the defective items may involve both a Type I and a Type II error. Due to the defective items and the inspection errors, shortages may sometimes occur. In this paper, we develop an economic order quantity model with imperfect quality items, inspection errors, shortage backordering, and sa...

In this paper the risk of supply chain disruptions is investigated in relations to different policies of inventory replenishment. The increasing attention to this issue in the academic and business, has strongly motivated the development of this work, above all to obtain analysis of costs in terms of distributions and variability. The goal is to enrich literature in constant growth and allow co...
