Members of supply chain carry inventory for different purposes. To effectively reduce the cost of inventory, information sharing mechanism is the key. The inventory can be managed in two ways in supply chain systems. The first one is the centralized inventory management system, in which, the information of inventory is highly exchanged among supply chain members. The other is the decentralized ...

SME LCR is one of the handicrafts in Yogyakarta, Indonesia. This produces several handicraft products such as storage baskets with various variants, and furniture. The process ordering raw materials for SMEs carried out when there a demand incoming order quantity based on material needs meeting product demand. study intends to provide recommendations improving governance overcome fluctuations d...

We study a periodic review inventory system with finite ordering capacity, and assume the variable cost would be discounted when quantity is full capacity. Applying concept of strong CK -concavity, we show that optimal pricing strategy could partially characterized by an ( S , ′, p ) in four regions depending on starting level per period. Numerical experiments verify proposed strategy.

Motivated by the widespread adoption of dynamic pricing in industry and the empirical evidence of costly price adjustments, in this paper we consider a periodic-review inventory model with price adjustment costs that consist of both fixed and variable components. In each period, demand is stochastic and price-dependent. The firm needs to coordinate the pricing and inventory replenishment decisi...

This paper examines “distribution policies” — that is, combined system inventoryreplenishment, vehicle routing and inventory-allocation policies — designed to minimize total expected purchasing and inventory-management (i.e., inventory-holding and backordering) costs/period for a one-warehouse N-retailer “symmetric” distribution system managed under a periodic-review policy. With respect to dyn...

We describe a periodic review inventory system where emergency orders, which have a shorter supply lead time but are subject to higher ordering cost compared to regular orders, can be placed on a continuous basis. We consider the periodic review system in which the order cycles are relatively long so that they are possibly larger than the supply lead times. Study of such systems is important si...

abstractaccidents and natural disasters and crises coming out of them indicate the importance of an integrated planning to reduce their effected. therefore, disaster relief logistics is one of the main activities in disaster management. in this paper, we study the response phase of the disaster management cycle and a bi-objective model has been developed for relief chain logistic in uncertainty...

A simulation based-decision support system for multi-product inventory control management is developed. The system permits management to obtain an inventory system-wide view of the effect of changes in decision variables on the performance measures of a furniture manufacturing firm. The simulation model considers the effect of variations in demand, reorder point, stock-control level, time betwe...

In this article, we develop a dynamic programming model for a periodic review inventory system in which emergency orders can be placed at the start of each period, while regular orders are placed at the beginning of an order cycle (which consists of a number of periods). We assume that the regular and emergency supply lead times di!er by one period. We devise a simple algorithm of computing the...

in the present paper the linear oscillator in r3 with z =constanthas been considered. the aim is to determine the necessary conditions forthe persistence of periodic solutions under discontinuous perturbations. a newapproach based on a computational method has been used. at the end weapply our method on an example.
