This project focuses on optimizing the location of WEEE collection points for waste electrical and electronic equipment (WEEE) which consists of determining a set of locations to install a network of gathering equipment. It is implemented using open source technologies following the current tendency of the present software market situation. In particular, the software application to be develope...

This study aims to develop a multi-period distribution system design model that provides an integrated view of the various costs, service quality and budget concerns within the planning horizon, as well as computationally feasible methods for obtaining solutions in realistic situations. The key design decisions considered in each period are: the number and location of distribution centers in t...

Intelligent infrastructure will critically rely on the dense instrumentation of sensors and actuators that constantly transmit streaming data to cloud-based analytics for real-time monitoring. For example, driverless cars communicate real-time location and other data to companies like Google, which aggregate regional data in order to provide real-time traffic maps. Such traffic maps can be extr...

the capacitated location-routing problem (clrp) is a new research area in logistics and distribution management. this problem combines two difficult problems: the facility location problem (flp) and vehicle routing problem (vrp). the goal of the clrp is to open a subset of depots, assign the customers into open facilities, and then design vehicle tours in order to minimize the total cost. the t...

increasing of the distribution efficiency is one of the most objectives of an integrated logistic system developed as a new management philosophy in the past few decades. the problem is examind in two parts: facilities location problem (flp) for long policies and vehicle routing problem (vrp) to meet the customer demand. these two components can be solved separately; however, this solution may ...

Title of dissertation: A STUDY OF FOUR NETWORK PROBLEMS IN TRANSPORTATION, TELECOMMUNICATIONS, AND SUPPLY CHAIN MANAGEMENT Si Chen, Doctor of Philosophy, 2007 Dissertation directed by: Professor Bruce Golden and Associate Professor Subramanian Raghavan Robert H. Smith School of Business The increasing material costs and the rapid advances in computing technology have both motivated and promoted...

In the dial-a-ride problem, users formulate requests for transportation from a specific origin to a specific destination. Transportation is carried out by vehicles providing a shared service. The problem consists of designing a set of minimum cost vehicle routes satisfying capacity, duration, time window, pairing, precedence and ride time constraints. This paper introduces a mixed-integer progr...

In this paper, we study an integrated logistic system where the optimal location of depots and vehicles routing are considered simultaneously. This paper presents a new mathematical model for a multi-objective capacitated location-routing problem with a new set of objectives consisting of the summation of economic costs, summation of social risks and demand satisfaction score. A new multi-objec...

The increased number of hazardous materials transportation accidents has caused a series of environmental and health problems across the world. In this paper, a hazardous materials transportation monitoring system (HMTM) is designed, implemented, and tested using multi-interface Wireless Sensor Networks (WSNs). In order to meet various state tanker transportation information collection, we desi...
