Financial Risks And Investment Decisions Based On Fuzzy Logic Analysis

With the development and scientific and technological progress, and there are a lot of fuzzy phenomenon has become impossible to circumvent the problem. Age 20 from the beginning of the 20th century, there are some scholarsbegan to consider and study how to describe the ubiquitous fuzzy Phenomena in objective world. For example the famous Philosopher and mathemaUcian—B·Russell. Professor Zadeh bring forward the Fuzzy theroy, but its development is uneven, because its traditional force makes a great handicap in West. Now we know that fuzzy logic slam the door not precision but meaningless precision. Fuzzy logic is in the ascendant in science and commerce. And it becomes pop theme recently.Theory and fuzzy logic to deal with financial risks linked to investment decision-making is the theoretical innovation of this article. Based on fuzzy logic theroy and model the thesis combines them with risk venture item decision, so it can be used to analyse and to study the factors which influence venture Item. The application of Fuzzy matrix and fuzzy comprehensive evaluation can carry through comprehensively analyse some indeterminate factors in risk venture item decision, the analytic hierarchy process (AHP) is used to define the weight of different factors. The advantages of fuzzy logic is that it has broken the "either-or" thinking of using a qualitative analysis of the ways to reflect deep-seated differences of things, accurately grasp the accuracy of things in order to fully reveal the contradictions in things and the development of rich content, in order to fully establish the basis of formal methods in the precision of logic can not solve the problem may be resolved. Fuzzy logic which sets the framework for the development of a strong momentum and a great superiority. This article has done its related issues are discussed.Financial risks as a result of the object of investment is generally high-tech projects, which is characterized by a high degree of difficulty, professionalism, and a number of factors affected the success of constraint. Financial decision-making so there are some unknown or uncertain factors. In this paper, fuzzy logic of fuzzy comprehensive evaluation method and the risk of investment projects to combine the decision-making, the risk of investment projects by constructing a model of decision-making decision-making, there are some uncertainties to make a comprehensive analysis, in response to the efficiency of the financial risks with irreplaceable role.
