In#ation uncertainty is introduced into a basic EOQ model and its potential to make mischief is explored. Among other things, it is shown that even when the expected rate of in#ation is less than the marginal cost of capital, the appropriate discount rate to use in computing a discounted expected total inventory cost will not necessarily be negative. Therefore, the classic EOQ square-root formu...
In this study, a deteriorating inventory problemwith andwithout backorders is developed. From the literature search, this study is one of the first attempts by researchers to solve a deteriorating inventory problem with a simplified approach. The optimal solutions are compared with the classical methods for solving deteriorating inventory model. The total cost of the simplified model is almost ...
We consider in this paper an Economic Order Quantity (EOQ) problem involving a single supplier that offers quantity discounts and allows retailers to delay payments. The retailers are tempted to form coalitions in order to minimize their costs. We propose a solution approach that generates stable coalition structures for the retailers taking into account the delay in payments and the discount q...
As the United States approaches the twenty-first century... in an information-based, transnational and managerial economy, it is becoming increasingly apparent that if we do not better negotiate race and ethnicity in our society, we will not adequately solve the problems of economic inequality and discrimination. Racial and/or ethnic divisions and competition shape our efforts to understand and...
Although the lot size problem (i.e., the economic order quantity model) has been widely accepted and used by researchers and practitioners, it has also been criticized by others on the grounds that not accounting for some of the hidden costs in inventory systems often lead to poor results. This paper postulates that estimating these hidden costs may be attained by applying the first and second ...
We consider the finite-horizon discrete-time economic order quantity problem. Kovalev and Ng (2008) have developed a solution approach for solving this problem. Their approach requires a search for the optimal number of orders, which takes O(logn) time. In this note, we present a modified solution method which can determine the optimal solution without the need of such a search.

Parallel algorithms for recognizing and representing interval orders are proposed for differ. ent models of parallel random access machines (PRAM). The algorithms accept as input a transitively~losed directed graph with N nodes and M edges. They run in time O0og N) with O(N + M~ processors and O{N + M} space and in co , tam time with O(N z) proces~rs and O{N ~) space depending on the data struc...
The development of the inventory model started when Harris introduced classic model. It was firstly published by Wilson using optimization method. He derived a mathematical equation to obtain economic order quantities. Later, this is known as Economic Order Quantity (EOQ) or Model. EOQ has some limitations. assumed that items do not have physical changes during planning period. This assumption ...
In many practical situations, the quantity of interest is difficult to measure directly. such estimate this quantity, we easier-to-measure quantities which are related desired one by a known relation, and use results these measurement quantity. How accurate estimate? Traditional engineering approach assumes that know probability distributions errors; however, in practice, often only have partia...
