Multi-objective Risk Decision-making Theory And Methodology Research

Decision making and our lives are closely related to each other, large to one country and region, smallness to one enterprise even individual and from day to day we have to do assorted decisions. Afterwards decision-making has become supervisory kernel problem in modern times. The world that we faced with today is complex, and filling with competition and abound defiance, and global new technological revolution rising is in company with socio-economic development at the same time. It is the time that they have to consider multiple decision making objectives, balance each aspect benefit and be confronted with international and inland assorted risks when highest class constitute strategic layout or countermeasure, medial class handle things of economic construction or produce management and lowest class arrange routine work, so which is to say that system and comprehensive concept must be brought hi our decision making, wherefore research into multiple objectives decision making under risk possess full realistic meaning. The system study of decision making science in our country begin hi the end of 1970s or beginning of 1980s, launching with reference and introduction of external decision making science theory, to this day, none but twenty years. Our research lever is lower versus external research of decision making science, only getting to digest and absorb western decision making theory level. The paper in some degree could exuberate, extend and perfect inland decision making science theory, fill up our research insufficiency, reduce gap with developed country in this science region.This paper does preliminary and systematic research on theory and means of multiple objectives decision making under risk, and following are its mostly innovation points: 1.Giving one new notions: multiple risks and establishment of mathematical model of multiple objectives decision making under risk and the new way of assured weight through the medium of sensitivity analysis.2. The new ways that solve multiple objectives decision making under risk into probability permanent type: decision making diagram method, matrix analysis method, multiple objectives Markov method , the shortest distance method, successive type variation multiple objectives decision making under risk method and fuzzy analysis decision makingmethod.3.The new modes that solve multiple objectives decision making under risk into probability interval type and uncharted type: weighted method and sorting method 4 The new repent average value criterion that handle multiple objectives decision making under risk into probability uncharted type and generalizing the criterions that have been used into one objective decision making under probability into uncharted type to multiple objectives decision making under probability into uncharted type.5.Giving the error analyses method and decision result regulating method that been used into multiple objectives decision making under risk.Our research is insufficient, so expecting specialists, professors, teachers and schoolmates criticizing and pointing out mistake, so that it can be corrected of.
