This paper develops a new mathematical model to study location-routing problem with simultaneous pickup and delivery under the risk of disruption. A remarkable number previous studies have assumed that network components ( e.g. , routes, production factories, depots, etc.) are always available can permanently serve customers. assumption is no longer valid when faces disruptions such as flood, e...

periodic vehicle routing problem focuses on establishing a plan of visits to clients over a given time horizon so as to satisfy some service level while optimizing the routes used in each time period. this paper presents a new effective heuristic algorithm based on data mining tools for periodic vehicle routing problem (pvrp). the related results of proposed algorithm are compared with the resu...

Multicast routing is one of the most important services in Multi Radio Multi Channel (MRMC) Wireless Mesh Networks (WMN). Multicast routing performance in WMNs could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. In this paper we want to address the multicast routing problem for a given channel assignment in WMNs. The channels...

We consider the two-echelon location-routing problem (2ELRP), a well-known problem in freight distribution arising when establishing a two-level transport system with limited capacities. The problem is a generalization of the NP-hard location routing problem (LRP), involving strategic (location), tactical (allocation) and operational (routing) decisions at the same time. We present a variable n...

In mobile ad hoc networks, nodes are dynamically changing their locations. The QoS information used for routing by traditional QoS routing protocols becomes obsolete due to node mobility. To overcome this problem, a predictive QoS routing scheme is needed. In this paper, we present a location-delay prediction scheme, based on a location-resource update protocol, which assists a QoS routing prot...

Location-routing problem (LRP) is a combinational optimization problem in a logistics system. Most heuristic methods employed for LRP divide the problem into location assignment and vehicle routing with a two-phase method, but this method often does not lead to a satisfactory result for the information can not be compressed from one phase to the other efficiently. In this paper we are concerned...
