摘要: DEFINITION A spatial decision support system (SDSS) is an interactive, computer-based designed to a user or group of users in achieving higher effectiveness making while solving semi-structured problem [10]. It lies at the intersection two major trends sciences: geographic information sciences (GIS) and analysis What really makes difference between SDSS traditional (DSS) particular nature data considered different problems high level complexity these problems. An effective requires addition range specific techniques functionalities, used especially manage data, conventional DSS. According [5], should (i) provide mechanisms for input (ii) allow representation relations structures, (iii) include analytical analysis, (iv) output variety forms, including maps. Multicriteria systems (MC-SDSS) can be viewed as part broader fields SDSS. The specificity MC-SDSS that it supports multicriteria making. Spatial refers use (MCA) MCA [7] family operations research tools have experienced very successful applications domains since 1960. has been coupled with geographical early 1990s enhanced
