A capacitated location-routing problem (CLRP) is one of the new areas of research in distribution management. It consists of two problems; locating of facilities and routing of the vehicle with a specific capacity. The purpose of the CLRP is to open a set of stores, allocate customers to established deposits, and then design vehicle tours in order to minimize the total cost. In this paper, a ne...

The refugee crisis is one of the major challenges modern society. influxes refugees are usually sudden and in sheer need services such as health care, education safety. Planning public under an imminent humanitarian requires simultaneous strategic operational decisions. Inspired by a real-world problem that Red Crescent facing Southeast Turkey, we study locating camps planning transportation se...

Hub ports play an important role in reducing the number of container routes and saving operating costs liner companies. However, hub failures caused by uncertainties such as natural disasters may cause huge recovery costs. Considering accidental failure probability reallocation feeder ports, a global reliable shipping location problem (RLSHLP) is studied. We use k-means algorithm to divide netw...

this paper addresses a reliable facility location problem with considering facility capacity constraints. in reliable facility location problem some facilities may become unavailable from time to time. if a facility fails, its clients should refer to other facilities by paying the cost of retransfer to these facilities. hence, the fail of facilities leads to disruptions in facility location dec...

One of the notoriously difficult problems in vehicular adhoc networks is to ensure that established paths do not break before the end of data transmission. This is a difficult problem because the network topology is changing constantly and the routing links are inherently unstable due to the high mobility of vehicles. This paper classified the existing routing protocols which are designed for v...

This paper studies a reliable facility location problem with facility protection that aims to hedge against random facility disruptions by both strategically protecting some facilities and using backup facilities for the demands. An Integer Programming model is proposed for this problem, in which the failure probabilities of facilities are site-specific. A solution approach combining Lagrangian...
