occurrence of natural disaster inflicts irreparable injuries and symptoms on humans. in such conditions, affected people are waiting for medical services and relief commodities. thus, quick reaction of medical services and relief commodities supply play important roles in improving natural disaster management. in this paper, a multi-objective non-linear credibility-based fuzzy mathematical prog...

The location-routing problem is the most significant and yet new research field in location problems that considers simultaneously vehicle routing problem features with original one for achieving high-quality integrated distribution systems in beside of the global optimum. Simultaneous pickup and delivery based on time windows are the two main characteristics of logistic management that have be...

Optimal routing is an important part of the methanol road transportation research. Optimal routing of methanol is different from those general optimal routing processes. Methanol optimal routing need to take into account the risk of path, the possible consequences of the accident and emergency response capabilities around the path and other factors This paper includes two aspects of research, o...

We propose a new method to perform urban routing efficiently under capacity constraints. This new method helps with evacuation routing as well as other urban transportation challenges. Traditionally, simulation software or shortest path routing combined with zonal scheduling have been used to solve routing problems. Our method utilizes a state-of-the-art algorithm to connect each source node to...

Unlike widely available literatures in hazardous material (HAZMAT) transportation that basically aim at finding non dominated paths for a given origin-destination pair, our main focus in this study is on vehicle routing problem with time window (VRPTW) aspect of HAZMAT transportation problem that has received very less attention in literatures. We present a new multi-objective optimization mode...

guiding vehicles to their destination under dynamic traffic conditions is an important topic in the field of intelligent transportation systems (its). nowadays, many complex systems can be controlled by using multi agent systems. adaptation with the current condition is an important feature of the agents. in this research, formulation of dynamic guidance for vehicles has been investigated based...

A great loss of transportation capacity has been caused in auto parts supply logistics due to the independent from suppliers (APSs) automobile production line (APL). It is believed that establishing distribution centers (DCs) for centralized collection and unified one effective way address this problem. This paper proposes a framework simultaneously considering location-inventory-routing proble...

118 Transportation Research Record: Journal of the Transportation Research Board, No. 1964, Transportation Research Board of the National Academies, Washington, D.C., 2006, pp. 118–126. Several noteworthy developments in logistics practice have taken place without an equivalent and comprehensive development in urban freight transportation modeling. Part of the problem is the lack of deep unders...
