An Inventory Model for Deteriorating Items with Quantity Dependent Permissible Delay in Payment and Partial Backlogging of Shortage

Abstract: Abstract: In many inventory situations, instead of making immediate payment on receiving the consigument, the purchaser is allowed a certain fixed time period to pay for the goods bought. During this time the supplier charges no interest, but beyond this period interest is charged under the terms and condition agreed upon. As for the purchaser, he can earn interest on the revenue coolected during the credit period. This paper studies a single item inventory model for deteriorating items, when the permissible delay in payment depends on the ordered quantity and shortages are partially backlogged, assuming the backlogging rate to be inversely proportional to the waiting time for the next replenishment. An algorithm has been developed to find the optimal inventory policy. Numerical examples have been cited to illustrate the model. AMS (2000) Subject Classification: 90B05.

An Inventory Model for Deteriorating Items with Permissible Delay in Payment and Inflation Under Price Dependent Demand

Abstract: The paper studies an inventory model for deteriorating items when demand for the item is dependent on the selling price. Shortages are allowed and backlogged, and price inflation is taken into consideration. Further, it is assumed that the supplier permits the inventory manager to settle his accounts within a given specified time period. Numerical examples are cited to illustrate the model and to study the sensitivity of the model to change in model parameters.

Inference on P(Y < X) in Generalized Uniform Distributions

Abstract: The paper considers estimation and testing of P(Y < X), when X and Y follow independent generalized uniform distributions with known shape parameters .

A deterministic inventory model with permissible delay in payment and price discount on backorders

Abstract: In this paper we study a deterministic inventory model with shortages, where only a fraction of the unmet demand is backlogged, and the inventory manager offers a discount on it. Conditions of permissible delay in payments are also taken into account. Numerical examples are cited to illustrate the model.

Exponentiated Transmuted Modified Weibull Distribution

Abstract: The paper introduces the exponentiated transmuted modified Weibull distribution, which contains a number of distributions as special cases. The properties of the distribution are discussed and explicit expressions for the quantiles, mean deviations and the reliability are derived. The distribution and moments of order statistics are also studied. Estimation of the model parameters by the methods of least squares and maximum likelihood are discussed. Finally, the usefulness of the distribution for modeling data is illustrated using real data.

Survey of Literature on Continuously Deteriorating Inventory Models

Abstract: This paper presents a complete and up-to-date survey of published inventory literature for the deteriorating (decaying) inventory models. More specifically, those papers are addressed that consider the effect of deterioration as a function of the on-hand level of inventory. The basic features, extensions and generalization of various models are discussed. A classification scheme is presented along with suggestions for future research.

Trends of male factor infertility, an important cause of infertility: A review of literature.

Abstract: Infertility and problems of impaired fecundity have been a concern through ages and is also a significant clinical problem today, which affects 8-12% of couples worldwide. Of all infertility cases, approximately 40-50% is due to "male factor" infertility and as many as 2% of all men will exhibit suboptimal sperm parameters. It may be one or a combination of low sperm concentration, poor sperm motility, or abnormal morphology. The rates of infertility in less industrialized nations are markedly higher and infectious diseases are responsible for a greater proportion of infertility. The present literature will help in knowing the trends of male factor infertility in developing nations like India and to find out in future, various factors that may be responsible for male infertility.

Lifestyle factors and reproductive health: taking control of your fertility

Abstract: Approximately 10 to 15% of couples are impacted by infertility. Recently, the pivotal role that lifestyle factors play in the development of infertility has generated a considerable amount of interest. Lifestyle factors are the modifiable habits and ways of life that can greatly influence overall health and well-being, including fertility. Many lifestyle factors such as the age at which to start a family, nutrition, weight, exercise, psychological stress, environmental and occupational exposures, and others can have substantial effects on fertility; lifestyle factors such as cigarette smoking, illicit drug use, and alcohol and caffeine consumption can negatively influence fertility while others such as preventative care may be beneficial. The present literature review encompasses multiple lifestyle factors and places infertility in context for the couple by focusing on both males and females; it aims to identify the roles that lifestyle factors play in determining reproductive status. The growing interest and amount of research in this field have made it evident that lifestyle factors have a significant impact on fertility.
