Spatial information systems and information integration

Analyse multicritère et SIG pour faciliter la concertation en aménagement du territoire : vers une amélioration du processus décisionnel?

“…La décision est un acte d'autorité déterminant ce qui doit être fait ou réalisé alors que le choix est une activité technique permettant de distinguer les scénarios d'action retenus, les uns des autres (Simon, 1977;Buogo et Chevallier, 1995). On comprend donc que la décision sera d'autant 3 9…”

A GIS based information integration framework for dynamic vehicle routing and scheduling

“…Moreover, the rapid advances in related technologies, such as computer systems, communication networks, Electronic Data Interchange (EDI) and Global Positioning Systems (GPS) has led to a renewed interest in researching and implementing dynamic vehicle routing and scheduling systerns Dynamic VRS is an information-intensive decision making process that integrates data from the public or private sectors involved in daily vehicle operations In the case of urban freight transportation, these could be road or municipal authorities, freight caniersldrivers, customers or retailers, etc Geographic Information Systems (GIs), were in past limited to the hnction of digital mapping in W, k t now they can be extended beyond traditional databases and integrated with many other types of information, i.e. management or statistic data, smart maps and analyses GIS can now perform a major role in spatial information based complex decision support systems (DSS) as VRS [ 5 ] and [6]. In this context, a welldevised information integration framework will be of great benefit in achieving the realisation of a feasible system Such a framework needs to include a description of the problem formulation, how uncertainty will be handled and how optimal decisions will be made…”
