Abstract vehicle routes for multiple vehicle routing problems. The

AbstractSummaryThisarticle is about easily-operatible web-based spatial decision support system (webSDSS)focus on creating optimized vehicle routes for multiple vehicle routingproblems.

The web-SDSS contain Google Maps™, a database management conponent, a heuristic and a systemdeveloped by the authors to make routes and detailed vehicle route maps. It containrealistic approch, such as vehicle capability and shift time constrictions, aswell as the network problems such as one-way, two-ways restrictions and prohibiatedattributes. webSDSS can be use for “what-if” analysis,the input parameters such us vehicle capacity, seasonal variations of demandmaximum driving time shift, and network updation is related to change. Only itneeds web browser, it is easy to adapt widely and is used in many realworld senerios.The system developed was experimently used for urban trash collection in theCoimbra, Portugal.  IntroductionSummary Theimportance and impacts of vehicle routing problems :In both sectors public or private the transportation of goods,Stuff and services is very considerable both environomental and economic pointof view.

Every industry wants efficient and fast access to the public , and noone can neglict the importance of efficient vehicle routing in this regard ,because due to this it can be reduce energy consumption , air pollution , andits truely a very big problem in almost all urban areas, mainly the vehiclemiles of traval (VMT) increase causing such type of vehicle routing problems. Sothere are an impact of vehicle routing problem on economic activities but alsoon the other hand there is an environomental impact. In urban context if thenumber of the vehicle increse the traffic congestion , noise and air pollution levelincrease.

The main approch which is built as for as envirnomental impactis concern is to consume lowest number of fuel to minimize emission of CO2, anddecreasing VMT can minimize carbon emission. Reducing VMT have an important impacton public health.             So to address all the issues discussedabove there is need for developing spatial decision support system for decisionsuporting purposes, this paper contains the methodological implementation ofweb-based spatial decision support system (webSDSS).
