We consider a continuous review inventory system that faces two different cases of demand processes. In one case demand follows a compound Poisson process. In the other case demand is a combination of a constant deterministic component and a random component which follows a compound Poisson process. We assume negligible lead time. Orders occur when inventory level drops to or below level zero, ...

The present work deals with the supply chain problems related to perishable products. The EOQ model has been used to analyze the data collected and suggest a ordering policy that will minimize the loses and maximize the organizational value. The work provides a suggestion for managers to take decision regarding use of self space and reordering of items depending on the inventory usage.

An inventory management system for defective items with backordered shortages is explored, in which we assume that the quality of an ordered lot is not always 100% perfect, so a screening process to each product is conducted to split that lot into perfect and defective products. Meanwhile, the defective products include imperfect and scrap ones, which will be sold at a discount price and dispos...

Many times it happens that units ordered are not of 100% good quality. A deterministic inventory model with imperfect quality is developed when the deterioration rate is Weibull distribution. Here it is assumed that holding cost is time dependent. The model has been framed to study the items whose deterioration rate increase with time under permissible delay in payments with imperfect quality. ...

United States is once again experiencing record levels of immigration. As with European immigrants arriving a century ago, concerns have been raised about the ultimate success of the new arrivals from Latin America and Asia (Suárez-Orozco and Suárez-Orozco 2001). Of particular concern are future prospects for children of immigrants who arrive with few human-capital resources and settle in racia...

The National Collegiate Athletic Association (NCAA) basketball tournament qualifies as a sports mega-event, and cities across the United States compete vigorously with one another to host what is, by most measures, the premier intercollegiate sporting event in the United States. The promise of substantial economic impact has convinced cities to “invest” substantial sums of money to meet the dem...

This paper aims to analyse the dependencies between supply chain performance, i.e. stock and stock-outs, and both supply chain management decisions and supply chain configuration parameters, i.e. the number of sources, the inventory capacity at a given node and the number of nodes that share the considered inventory capacity, the distance between nodes and the number of levels of the supply cha...

The standard inventory problems of multi-period have been modeled under different situations, namely we consider whether demand subjects to a continuous distribution or a discrete distribution and whether demand of each period is unchanged or not. A method to get an economic order quantity in inventory systems with discrete and unchanged demand was presented in former paper and this method has ...

This paper presents inventory models for perishable items with stock dependent selling rate. The selling rate is assumed to be a function of current inventory level and rate of deterioration is taken to be constant. Under instantaneous replenishment with zero lead time, the model incorporates aspects such as complete, partial, and no backlogging. EOQ is determined for maximizing the total profi...

Ford Whitman Harris first presented the familiar economic order quantity (EOQ) model in a paper published in 1913. Even though Harris's original paper was disseminated widely, it apparently was unnoticed for many years before its rediscovery in 1988. During this period much confusion developed over the origin of the EOQ model. This paper explores the early literature on this model and traces th...
