Advanced OR and AI Methods in Transportation A GRAVITATIONAL APPROACH FOR LOCATING NEW SERVICES IN URBAN AREAS1

چکیده
In this work we face the problem of locating new services in urban areas. Given a digraph whose nodes represent urban zones and arcs are the flow connections between them, we have to decide in which node new service centers can be optimally located on the basis on the evaluation of the efficiency of other centers that have been previously located in different nodes. We first derive the main parameters that could influence this locative choice and present a model originating from the classical gravitational and attractivity approach used in the competitive location problem. This well known model is here originally applied in the presented case study related to the city of Genoa, Italy, where we had the need of evaluating different locations for opening food and rest service centers.

Modified particle swarm optimization algorithm to solve location problems on urban transportation networks (Case study: Locating traffic police kiosks)
Nowadays, traffic congestion is a big problem in metropolises all around the world. Traffic problems rise with the rise of population and slow growth of urban transportation systems. Car accidents or population concentration in particular places due to urban events can cause traffic congestions. Such traffic problems require the direct involvement of the traffic police, and it is urgent for the...

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...
