Automatic suitable-matching area selection is an important research in visual guidance, scene matching and local non-texture target tracking. Meanwhile, it is the major research subject in computer vision and accurate guidance. In this paper, a new characteristic quantity, i.e., the edge direction dispersion was defined. Then the computation method, parameters selection and real-time realization of...
Optimization of real estate portfolio is to select two or more different types of real estate for investment, and the previous models based on expected return-variance cannot meet the needs of the investors. Furthermore, the investors change their risk preference with the risk level.

With respect to the multiplicative complementary judgement matrix, n groups of approximate weight vectors are given by considering the judgement informations in detail provided by decision makers (DMs) in this paper. And some information aggregation operators are used to aggregate these approximate weight vectors according to the credibility degree of alternatives into judgements defined in this paper,...
With respect to decision table, especially the inconsistent ones. On the basis of equivalent partitions, This paper quantifies the elements in the same class deduced by condition attribute belonging to different decision attribute classes, generates the discernibility matrix and measures the indexes of attribute significance reasonable, and then uses these formulas as heuristic information to design...
Considering a dearth of comparing construction project transaction method, from the point of transaction costs, the overall construction project transaction costs is divided into ex ante transaction costs, construction costs, ex post transaction costs. A framework for comparing construction project transaction method is presented, and applied to a detailed analysis of the department of Taihu drainage...
