A Survey of finding locations for fire fighting stations in semnanby utillzation geography information system

Fire fighting stations and their locations in helping and rescuing people areconsidered to be very important in cities. fire fighters can have an important role inproviding comfort and security for their citizens and economy of the cities.So, giving proper and on time Services via fire fighting stations requires them to bestationed at good locations.The main purpose of establishing fire fightings stations isto provide part of the security in cities for the purposes mentioned above. For reachingthis goal, unified systematic view function in cities ingredient in micro level anddirection cities structure in the macro level is importan whieh is achieved more eventin geographical information system .In this reserch,the main goal is to find the bestlocation for fire fighting in semnan, or to transfare some of the stations from theirpresent locations if neccessary.In this research,attempts have beenmade to find themost appropriate places for the fire fighters to be stationed at new places. Therefore,inorder to find scientific and exact places a combination of geographical informationsystem GIS and AHP has been used .After priamcary studies and gathering useful datafor setslaction in the fire fighting .The effective criteria were dividied in to six groupsand , then by means of analytical hierarchy process the weight of each criteria wasdetermind and finally was mixed by means of index overlay .The results with highflexibility were offered in six forms. After putting together the plans obtained,firstproper initial restrictions were proposed. Then the exact position of each proposedstation within this boundary was determind in a way that they are able to cover themaximum area and give services. At the end, a part from the existing stations twomore were added and five new stations were suggested.
