With the advent of technologies like RFID, it is now possible to track inventory in the real time. In case of RFID enabled Supply Chain the physical inventory and the system inventory is same, while in the traditional supply chain the physical inventory varies from the system inventory due to shrinkage, transaction and misplacement error. We developed a simulation model to study the traditional...

The purchasing policy of spare parts for maintenance and the reverse inventory chain logistics has been attracting researcher’s attention in recent years. In spare parts (SP) inventory control the aim is to maintain the inventory at an optimal level and to minimize the purchasing and the inventory costs. This paper deals with integration of the recycled spare parts in the economic models of inv...

Separate literatures exist to describe responses of timber owners and aggregate timber supply to product prices. While few investigators have alluded to the effects of varying inventory quality and ownership mix on the aggregate response, it is possible to describe how the responsiveness to prices can vary over time as the vintage of the timber inventory shifts. We estimated a probit harvest mo...

In this study, a deteriorating inventory problemwith andwithout backorders is developed. From the literature search, this study is one of the first attempts by researchers to solve a deteriorating inventory problem with a simplified approach. The optimal solutions are compared with the classical methods for solving deteriorating inventory model. The total cost of the simplified model is almost ...

While the Edinburgh Handedness Inventory has been widely used, there have been few studies assessing its factorial validity. There is evidence that the original instructions and response options are difficult to understand. Using simplified instructions and response options, the Edinburgh Handedness Inventory was administered on a sample of 1514 participants using an online questionnaire. In ac...

this paper considers the fuzzy inventory model for deteriorating items for power demand under fully backlogged conditions. we define various factors which are affecting the inventory cost by using the shortage costs. an intention of this paper is to study the inventory modelling through fuzzy environment. inventory parameters, such as holding cost, shortage cost, purchasing cost and deteriorati...

The primary consequence of just-in-time (JIT) production is reduction of inventory. The associated benefit is (a) improved cashflow due to less financial resource tied up in inventory, and (b) less storage space required hence more productive plant area. Coupled with lean production and total quality management (TQM), it may also be possible to (c) improve worker productivity, (d) improve produ...

In this paper an uncapacitated multiple allocation p-hub median problem is discussed. The model minimizes the transportation cost based on inventory service level at hubs through double paths between hubs. Inventory service level is defined as the percent of inventory shortage of vehicles at hubs according to passengers demand and replenishment time of vehicles. A real data from 25 nodes of mun...

classical deterministic inventory models consider the demand rate to be either constant or time-dependent but independent from the stock status. however, for a certain type of inventory, the demand rate may be in-fluenced by the stock level. also in many real-life problems, some products such as fruits, vegetables, phar-maceuticals and volatile liquids continuously deteriorate to evaporation, o...

In this paper, it was an attempt to be present a practical perishability inventory model. The proposed model adds using spoilage of products and variable prices within a time period to a recently published location-inventory-routing model in order to make it more realistic. Aforementioned model by integration of strategic, tactical and operational level decisions produces better results for sup...
