Multi-objective Risk Type Of Investment Decision-making Research

In the analysis on investment decision, many factors should be taken into full consideration. This paper throws light on it in three aspects:The first section deals with the introduction of some concepts related to the multiobjective risky decision in investment, such as investment, risk, multiobjective decision, risky decision, etc. Also, this section gives us a short survey of some investment characters, such as multiobjective, profit, risk, etc, and points out that much importance should be attached to the study of the multiobjective risky decision in investment.The second section introduces some common methods and evaluation indexes, such as net present value, internal rate of return, payback period, profitability index, etc. The present methods and evaluation indexes are incomplete, which mainly apply to the analysis on the determinate decision. In fact, they are mono-objective and most-favored methods. These standards, due to which even mistaken decisions are caused, can never meet the need of the analysis on the multiobjective risky decision in investment.As a better choice, this paper puts forward the principles about the analysis on it, including Sharp index and Lint index, expected utility net, etc.The third section establishes a multiobjective risky decision model. This model takes the expected utility net for decision standard, and it enables us to thoroughly analyze the characters of investment and to evaluate the profit and risk of investment plan by applying the method of multiobjective decision. This model contributes to make correct decision.In a word, this paper puts forward a multiobjective risky decision model in view of the present incomplete decision indexes and methods in investment with the switch from the mono-objective determinate decision to the multiobjective risky one, which leads to more scientific investment decision.
