The impact of decision-making during environmental mutation -Substantial change of fuzzy error system

Environmental mutations always happen around all the systems, according to the impact of these changes which seems to be innocuous, the decision makers may often neglect or considered less about them, so that these systems will often pay their price. Through the exploration for the mutation of fuzzy error system, the status and characteristics of its model can be analyzed. Therefore, the decision-maker can adopt corresponding tactics to handle the intensive change of decision-making environment. At the same time, by the study for the mutation of error, it can provide a quantitative tool for scientific decision making. The major aim of this paper is to give a foundation for the application of the mutation of fuzzy error system. It will have widespread application in the actual live. By studying this theory, the case that has significant change in decision-making courses can be solved.
