Product perishability is a major concern of certain industrial sectors, especially the agro-food industry. This paper investigates the effect of product perishability and retailers’ stockout policy on system total cost, net profit, service level, and average inventory level in a two-echelon inventory–distribution system, and develops an approximate inventory model to these system performance me...

a new mathematical model for the optimal production isformulated for the inventory management system under time-varyingand stochastic inflation environment for deteriorating items. the timehorizon is finite and demand rate is dependent to the inflation. in thereal situation, some but not all customers will wait for backlogged itemsduring a shortage period, such as for fashionable commodities or...

We discuss plausible locations of radiating regions in the magnetospheres of pulsars and argue that the mechanisms of pulsar radiation at different frequencies are closely connected with the locations of the radiating regions, especially in the radio range. If the region that is responsible for the bulk of the non-thermal radiation at some frequency is localized in the pulsar magnetosphere then...

an unassuming entrance where once passed Alan Turing, Tommy Flowers, and the thousands of men and women who labored in secrecy. Collectively, they changed the outcome of World War II; individually, the contributions of a few laid the foundations of computing. Until recently, a strong possibility existed that Bletchley Park would be lost to modern development. Thanks to the efforts started by To...

In this paper, topological properties of Wijsman hyperspaces are investigated. We study the existence of isolated points in Wijsman hyperspaces. We show that every Tychonoff space can be embedded as a closed subspace in the Wijsman hyperspace of a complete metric space which is locally R.

We report 60 and 90 m observations of seven millisecond pulsars with the Infrared Space Observatory. The pulsar PSR B1257+12 is orbited by three planets, and other millisecond pulsars may be orbited by dust disks that represent planets that failed to form or their residue. We do not detect any infrared emission from the seven pulsars in our sample, and typical upper limits are 100 mJy. Using a ...

In this paper, we show that for an almost locally separable metrizable space X, if its Wijsman hyperspace induced by one compatible metric is Baire, then X itself must be Baire. We also provide an example to demonstrate the necessity of separability.

Moreover, aspects calculation profits, as well limitations compensation discussed. author compares under with Polish private law. expresses his standpoint which law is quite similar, but by no means identical. in two c...

We consider a continuous review inventory system for model involving lost sales reduction through capital investment cost function and the of lead time further which reduces ordering cost. To reduce rate, two forms function, viz. logarithmic power are employed. Two relationships between time, linear considered. develop four models by taking different combinations relationship. Objective study i...
