<p style='text-indent:20px;'>The main purpose of this paper is to investigate the retailer's strategy in selecting order-up-to level, reorder point and preservation technology investment for deteriorating items, aiming maximize his total profit per unit time. We formulate problem into a mathematical model that takes account stock-dependent demand rate, holding cost. The terminal condition...

An inventory model of a volume flexible manufacturing system for a deteriorating item is developed, taking a stock -dependent demand rate. It is assumed that the demand rate remains stock-dependent for an initial period after which a uniform demand rate follows as the stock comes down to a certain level. The unit production cost is taken to be a function of the finite production rate which is t...

In healthy, non-challenged individuals, the secretion of cortisol typically follows a diurnal profile characterized by a peak in the period following waking (cortisol awakening response) and a gradual decline throughout the day. In addition, cortisol secretion is increased in response to acutely stressful stimuli, particularly stressors involving social evaluation. The current study is the firs...

This paper investigates the backorder rate inventory problem with defective units. In practice, the uncertainties of customer’s demand and backorder rate are inherent; hence, backorder rate and customer’s demand are not constant. In this study, we assume that the backorder rate is dependent on the amount of shortages and backorder price discounts, and the lead time demand follows a mixture of d...

Over two decades, a problem of location dependent has been focused for improving the communication Bandwidth-Power Efficiency of homogeneous networks. The efficiencies of communication links are weakened by the Hidden Terminal Problem.  Thus we propose a Fine – Tune Strategy for analyzing the On-Off communication region. We were observed that the proposed technique had been able to track and mo...

Abstract             In this research, an integrated inventory model for non-instantaneous deteriorating items is analyzed when demand is sensitive to changes in price. The price used in this research is a time-dependent function of the initial selling price and the discount rate. To control the deterioration rate of items at the storage...
