The timely and continuing adaptation of companies to the rapid changes in the market is a prerequisite to survival and growth. Simultaneously, the smooth adaptation of employees to changes contributes not only to the improved running of organizations but also to their personal improvement and...

Attempt has been made to investigate the reasons of poverty, flaws in reduction of poverty, lack of resources of dissemination of donor’s funds in real time. Previous studies reveal that there are various reasons behind poverty in the world especially in the developing and under developed...

The aim of this paper is to find out the techniques and suggest computer-based solution to reduce poverty from Pakistan, and suggest sustainable management of micro-Finance and Self-help Finance systems. Literature review at national and international level reveals that many researchers have...

In this paper we consider the classical newsvendor model with profit maximization. When demand is fully observed in each period and follows either the Rayleigh or the exponential distribution, appropriate estimators for the optimal order quantity and the maximum expected profit are established...

This paper considers the classical Newsvendor model, also known as the Newsboy problem, with the demand to be fully observed and to follow in successive inventory cycles one of the Exponential, Rayleigh, and Log-Normal distributions. For each distribution, appropriate estimators for the optimal...

This paper considers the classical newsvendor model when, (a) demand is autocorrelated, (b) the parameters of the marginal distribution of demand are unknown, and (c) historical data for demand are available for a sample of successive periods. An estimator for the optimal order quantity is...

In this paper we investigate the convexity of the annual total cost function for the Hadley & Whitin (1963) continuous review (Q,R) inventory model with backorders and fixed lead-time, when the reorder point is non-negative and the cost per unit backordered is used to calculate the expected...

Three estimation policies for the optimal order quantity of the classical newsvendor model under exponential demand are evaluated in the current paper. According to the principle of the first estimation policy, the corresponding estimator is obtained replacing in the theoretical formula which...
