In this paper, a closed-loop location-inventory problem for spare parts is presented. The proposed supply chain network includes two echelons, namely (1) distribution centers (DCs) and repairing centers (RCs) and (2) operational bases. Multiple spare parts are distributed among operational bases from distribution centers in the forward supply chain and failed spare parts from operational bases ...

In this paper, we propose an optimisation model to determine the product assortment, inventory replenishment, display area and shelf space allocation decisions that jointly maximize the retailer’s profit under shelf space and backroom storage constraints. The variety of products to be displayed in the retail store, their display locations within the store, their ordering quantities, and the all...

an integrated model considers all parameters and elements of different deficiencies in one problem. this paper presents a new integrated model of a supply chain that simultaneously considers facility location, vehicle routing and inventory control problems as well as their interactions in one problem, called location-routing-inventory (lri) problem. this model also considers stochastic demands ...

The efficient design/redesign of the logistics network is essential for companies to maintain their competitive advantage. This paper presents a novel non-linear mixedinteger programming model for the multi-product capacitated location routing inventory problem (MPCLRIP), where a two-layer distribution system consisting of depots and customers was studied. The supply decisions such as location ...

We consider a supply chain consisting of n locations replenished at the beginning of each period by a supplier. These locations may coordinate in order to balance their inventory level through transshipment. Transshipment is the items transfer from location having an inventory excess to another in need. The transshipment problem consists to determine the initial inventory level where a transshi...

This paper describes the design and implementation of a senior project based on RFID (Radio Frequency Identification) technology. The objective of the project, titled “Real Space Physical Object Tracking System (RSPOTS), was to design a complete RFID system that can physically locate an individual object from anywhere in the world via a secured Internet connection. By incorporating two or more ...

Previous studies on multi-location inventory systems with transshipments have focused mainly on periodic review systems with no fixed ordering cost. Since continuous review systems are also frequently used in practice, this research develops a multi-location inventory transshipment model that combines the popular order-quantity, reorder-point (Q,R) system with a third parameter, the hold-back a...
