Abstract

In this paper a decision facilitating and advising system (D-FAS), devised to help decisionmakers make quality fire-control preparation decisions in a North Carolina state park, is presented. This domain-specific decision support system provides assistance to decisionmakers that are at different levels of expertise and in various supporting needs. More specifically, as a facilitator , D-FAS increases the decisionmakers' accessibility to sophisticated decision strategies by making them as easy to employ as those simpler but less accurate methods that decisionmakers currently use; as an advisor , D-FAS minimizes uncertainties associated with the availability of expertise by systematically capturing decisionmakers' expertise and making it available to the novice and/or naive decisionmakers. Constructed on the basis of three mathematical techniques—the fuzzy relation, the α-level-set, and fuzzy composition—these capabilities are made feasible by the use of a computerized geographic information system.
