EFFECT OF INFLATION ON SUPPLY CHAIN MODEL WITH EXPONENTIAL DEMAND

In this paper, the inventory models assumed that the production rate of a manufacturing system is often assumed to be constant, but in fact production rate is a variable under managerial control. Production rate may be influenced due to demand, on hand inventory and launching new competitive product or with the change in customer’s preferences. A great number of authors have studied problems connected with constant production rate by taking different deterioration and demand rate. But when a new product is launched in the super market, demand increases more rapidly as time progresses.

IN INVENTORY ORDER LEVEL SYSTEM WITH POWER DEMAND AND PARTIAL BACKLOGGING

In this paper, most of the researchers have assumed that shortages are completely backlogged or completely lost. Consequently, the opportunity cost due to lost sales should be considered in the modeling. In the present work an inventory model is developed and analyzed with partial backlogging. The backlogging rate is taken to be inversely proportional to the waiting time for the next replenishment. Deterioration rate is taken as time dependent and concept of life time is taken in consideration, which is a realistic situation for the fresh and new items in stock.

A New Proof Of Menelaus's Theorem Of Hyperbolic Quadrilaterals In The Poincare Model Of Hyperbolic Geometry

In this study, we present a proof of the Menelaus theorem for quadrilaterals in hyperbolic geometry, and a proof for the transversal theorem for triangles.
