As the security assessment of power production is a complicated multi-attribute evaluation problem, this paper applied the gray target assessment model of gray system theory to the security assessment of power production according to the system engineering theory. And using optimization theory and Jaynepsilas maximum entropy principle a method of determining the linear combination weights based on...
Risk appraisal, in which the input and output of alliance is evaluated quantify, is the important stage in the overall performance appraisal of enterprise technology alliance. In this paper, on the basis of index system of risk appraisal of alliance, appraisal model with entropy has been established. The author believes that would be reference to come into being steady alliance between enterprises.
Based on the maximum entropy theory, this paper presents a new model for solving the large scale portfolio problem. Unlike Markowitzpsilas model, this new model is not based upon any probabilistic assumption on the distribution of stock data in the market, so it is more suitable for the solution of real problem. By some simplification, we derive a convex program model. It is with separable variables...
The real estate industry has been the pillar industry of national economic. And the high returns and high risks would coexist in this industry. First, this paper established the real estate portfolio model based on information entropy, with the smallest risk as the greatest benefits. In addition, this paper developed a new algorithm to find the optimal real estate portfolio to achieve the smallest...
