A study of two warehouse inventory systems with a production unit is developed in this article some constraints which are practical applicability to optimize the total cycle and its cost. evolves three different states retain quality prolong lifetime: state producing items, reworking identified defective being idle. It processes items up certain time point. The screening process starts immediat...

The practical experiences reveal that the inflation is non-deterministic and variable. Therefore, a mathematical model for the optimal production for an inventory control system of deteriorating items is formulated under time-varying and stochastic inflation environment. The demand rate is a function of inflation and the time horizon is finite. In the real situation, some but not all customers ...

In this paper we develop an inventory model, to determine the optimal ordering quantities, for a set of two substitutable deteriorating items. In this inventory model the inventory level of both items depleted due to demands and deterioration and when an item is out of stock, its demands are partially fulfilled by the other item and all unsatisfied demand is lost. Each substituted item incurs a...

Now-a-days, ventures are confronting numerous difficulties to meet the objectives of sustainable development. The Client’s choices changing at a quicker speed in view new advances and quickly general climate. It is seen that demand items straightforwardly associated with stock level however keeping colossal reason for increment holding cost crumbling effect. major test sell whole lot before its...

In this note, we consider a variation of the economic order quantity (EOQ) model where cumulative holding cost is a nonlinear function of time. This problem has been studied by Weiss (1982), and we here show how it is an approximation of the optimal order quantity for perishable goods, such as milk, and produce, sold in small to medium size grocery stores where there are delivery surcharges due...

In this study we have discussed a fuzzy eoq model for deteriorating products with time varying deterioration under inflation and exponential dependent demand rate. Shortages are not allowed in the impact of is investigated. An inventory used to determine whether order quantity more than or equal predetermined declining items.The optimal solution existing derived by taking truncated taylor’s ser...

proper inventory control policy and the optimal price for the items has always been one of the main topics of scientific research and industry. on the other hand, there are many products in the market witch are classified as deteriorating items. therefore the problem of determining optimal price and optimal inventory policy for this type of items is very important. in this paper a 3 echelon sup...

This paper considers the uncapacitated lot sizing problem with batch delivery, focusing on the general case of timedependent batch sizes. We study the complexity of the problem, depending on the other cost parameters, namely the setup cost, the fixed cost per batch, the unit procurement cost and the unit holding cost. We establish that if any one of the cost parameters is allowed to be time-dep...

<p style='text-indent:20px;'>In the business world, both supplier and retailer accept credit to make their position strong, because not only strengthens relationships but also increases scale of profits. In this paper, we consider an inventory model for non-instantaneous deteriorating items with price sensitive demand, time varying deterioration rate under two-level trade policy. Besides,...
