A Multi-item inventory model with increasing holding cost, under available limited storage space and total investment cost is considered in this paper. The varying holding cost is considered to be a continuous function of production quantity. A demand dependent on unit cost has been considered and this unit cost is taken in fuzzy environment. The model is solved using Kuhn-Tucker conditions met...

In this paper we shall discuss with the optimal ordering policy for two warehouse inventory model of non-instantaneous deteriorating items and stock-dependent demand. Here shortage is not allowed. Here the holding and deteriorating costs in both warehouses are different and assumed that the holding cost in the RW(rented warehouse) than in the OW(owned warehouse) the optimal solution are shown. ...

This paper studies the competitive and cooperative selection of inventory policies in a two-echelon supply chain with one supplier and N retailers. Stochastic demand is monitored continuously. Retailers incur inventory holding and backorder penalty costs. The supplier incurs holding costs for its inventory and backorder penalty costs for backorders at the retailers. The latter cost reflects the...

In recent years, various researchers have discussed a two warehouse inventory system. This kind of system was first discussed by Hartely (1976) [10]. Hartely presented a basic two-warehouse model, in which the cost of transporting a unit from rented warehouse (RW) to own warehouse (OW) was not considered. Sarma (1983)[20] developed a deterministic inventory model with infinite replenishment rat...

The paper is to present a simulation method to search for an optimal (z, Z) (z < Z) values for the (z, Z) production control policy so that the expected inventory cost rate (i.e. expected total cost due to both inventory holding and backlog per unit time) is minimal for a single machine system with buffer. The system is subject to operationdependent failure only and alternates between normal an...

The goal of supply chain management is to provide products with best quality, low costs and shortest delay of delivery corresponding to customers’ expectations. To ensure that, companies must be in continuous research for management methodologies which allows them the possibility to improve their financial results by decreasing costs and improving their process and thus customers satisfaction. ...

The fundamental question encountered in acquiring capacity to meet nonstationary demand over a multiperiod horizon is how to balance the trade-off between having insufficient capacity in some periods and excess capacity in others. In the former situation, part of the demand is subcontracted while, in the latter, capacity that has been paid for is rendered idle. Capacity and subcontracting decis...

When a manufacturer places repeated orders with a supplier to meet changing production requirements, he faces the challenge of finding the right balance between holding costs and the operational costs involved in adjusting the shipment sizes. We consider an inventory whose content fluctuates as a Brownian motion in the absence of control. At any moment, a controller can adjust the inventory lev...

During times of inflation, the use of the last-in, first-out (LIFO) method of inventory valuation has the effect of lowering the reported earnings by excluding inventory holding gains from this number. Current income tax payments due on the reduced earnings are also lower. Taxes payable on inventory holding gains, therefore, are postponed until some future period when the inventory is liquidate...
