Market characteristics, including intrinsic demand and customer sensitivity on price and product performance level, are distinct at different markets. Comparisons of various product development strategies in one market or two geographically separated markets are conducted for three classes of products: development intensive products (DIPs) with constant unit cost, marginal cost-intensive produc...

this study considers an eoq inventory model with advance payment policy in a fuzzy situation by employing two types of fuzzy numbers that are trapezoidal and triangular. two fuzzy models are developed here. in the first model the cost parameters are fuzzified, but the demand rate is treated as crisp constant. in the second model, the demand rate is fuzzified but the cost parameters are treated ...

Abstract: In this paper a study has been carried out using crisp and fuzzy inventory model for the deteriorating items under trapezoidal fuzzy numbers when the supplier offered price discount to the retailer at the time of replenishment. In this model the deterioration rate is constant. Many researchers suggested, demand rate in the inventory models are constant, exponential (increase/decrease)...

This paper reports on our progress in developing an advanced video-on-demand (VOD) testbed, which will accommodate various multimedia research and applications such as Electronic News on Demand, Columbia’s Video Course Network, and Digital Libraries. Two different prototypes have been completed. The first generation of the testbed was based on a constant-bit-rate (CBR) video server utilizing Et...

In this era of globalization and constant innovation, the life cycles of products are diminishing, which tends to cause dynamic behaviour in the system, and because of this, there is a constant introduction of new products in the market. Therefore, while developing inventory models for new products, it becomes necessary to consider dynamic parameters associated with the demand function and resp...

Although beef demand improved modestly in 1999, 20 years of declining demand has plagued the beef industry. Inflation-adjusted retail beef prices were collapsing at the same time per capita consumption was declining. The result, beef demand declined precipitously from 1980 through the late 1990s. For example, Purcell’s beef demand index indicates 1998 Choice retail beef prices were 50 percent l...

where ν > 1 denotes the elasticity of substitution between varieties. As before, the set of available goods at Home ∆′ has measure N . It follows that the demand for good i is given by qi = [pi P ]−ν Q, where pi is the price of good i, and P = [∫ i∈∆′ p 1−ν i di ] 1 1−ν is the price of the aggregate consumption good Q. The total consumption expenditure of the representative Home household is gi...

Seasonal items like fruits, fish, winter cosmetics, fashion apparel, etc. generally exhibits different demand patterns at various times during the season. Production and inventory planning must reflect this property for cost effectiveness and optimization of resources. This paper presents two production-inventory models for perishable seasonal products that minimize total inventory costs. The m...

It is not clear what factors contribute to the prompt and reversible decrease in left ventricular diastolic chamber distensibility during angina pectoris that is induced by an increase in myocardial energy demand due to exercise or pacing tachycardia. To simulate the demand ischemia that occurs clinically during pacing-induced angina, we used isolated, blood-perfused rabbit hearts with restrict...

In this paper, we consider the pricing decision of a retailer who experiences peak demand for a product during a given time interval and wishes to stabilize the demand by adjusting the sales price. The stabilization of demand brings about desirable outcomes such as a reduction in the need for capacity investment and improves the production efficiency in the supply chain. We establish a continuo...
