Abstract: This dissertation has combined the STEM method with fuzzy multiple-objective decision-making to put forward a multiple-objective interactive method which can reduce the complexity and difficulty in the interactive process of dealing with mutiple-objective problem. The important interactive table is the interface of analyser with computer which accepts the input-information and outputs problem's optimum solution. The dissertation has tried making use of the idea and utilities of artificial intelligence to make the auxiliary knowledge base with the non- structured information and analyser experience and inference mechanism to guide interactive process. A Chinese software package of this method which title is "Interactive Multiple-Objective DSS System" is developed using C and PROLOG languages. The practical application in agriculture proves that the method and the software package is effective and utility.
