DECISION SUPPORT SYSTEM IN CITY LOGISTICS

摘要

Finding efficient and cost acceptable solution for supporting processes in city-logistics leads to multi-user multi-layer hybrid simulation systems incorporating latest technology achievements: from sophisticated computer and database systems thru latest large data set computing metaheuristic algorithms to Global Positioning Systems and other status update systems (exceptional traffic, hour/weekday traffic levels). In this paper example approach to design of Decision Support System (DSS) in city-logistic is presented. This includes proposition of multi-layer simulation system that incorporates existing hardware and software solutions (Data Center technology, TransCAD as pre and post processing GIS) and new metaheuristic solution algorithms (with experimental verification) and system topology design which make it more suitable for needs and economic capability of potential users. Although this paper concerns preliminary approach to creation of such system - currently extensive work is done to fully implement ideas presented and successfully verified on benchmarking sets.
