In this paper, a comprehensive model for hub location-routing problem is proposed which no network structure other than connectivity is imposed on backbone (i.e. network between hub nodes) and tributary networks (i.e. networks which connect non-hub nodes to hub nodes). This model is applied in public transportation, telecommunication and banking networks. In this model locating and routing is c...

(ABSTRACT) This research is concerned with the development of algorithmic approaches for solving problems that arise in the design and analysis of telecommunication networks, location-allocation distribution contexts, and intelligent transportation networks. Specifically, the corresponding problems addressed in these areas are a local access and transport area (LATA) network design problem, the...

This paper studies the effect of branching rules (BR) and heuristic algorithms (HA) to find feasible solutions for a branch and bound (BB) algorithm used to solve sub-problems in a parallel two-phase branch and bound (PTBB) approach. The nine PTBB algorithms, which are developed by varying 3 combinations of BR and HA strategies, are tested on the facility location-transportation problem for dis...

The pick-up and delivery problem (PDP) consists in finding a set of optimal routes for a fleet of vehicles respecting the precedence and pairing constraints and visiting all transportation requests. The transport of personnel on oil platforms is a real application of PDP which we are interested in. The problem is modeled as a set covering problem that is solved via a column generation technique...

This article focus on Cybernetic Transport Systems (CTS) due to their effectiveness for solving mobility problems in cities. A new mobility concept is proposed which allows to attain the same flexibility of the private passenger car but with much less nuisances. It is based on small semiautonomous electric vehicles, which may be used to complement mass public transportation, by providing passen...

1- introduction transportation and traffic is one of the major issues and challenges that are facing urban managers. so that it has become one of the major challenges in the political area. transport is one of the most important elements of urban development which is used for people and goods moving from a different geographical place to other places. in order to achieve efficient productive in...

This paper developed a mathematical model framework using the single allocation strategy for hub covering location problem. The model encompassed the transportation time covering under gradual decay function. Within a certain transportation time for the origin and destination nodes among two hubs, the route is fully covered, and beyond another specified transportation time the route is not cove...
