In today's economy and society, performance analyses in the financial service industry attract more and more attention. The 7 largest Canadian Schedule I banks operate very large nationwide branch networks in all markets. They are not only essential for the security and strength of the Canadian financial system, but also make significant contributions to the economy across the country. They continue...
In order to get rid of the limit of traditional methods and provide a decision making reference for the supervision of securities organizations and the risk control of investors, A novel model based on SOM2W network (SOM with 2 winners self-organizing map) is proposed for assessment financial performance of the listed companies. In addition, a tabu-mapping method is proposed to avoid that the same...
This paper analyzes the defects of the present method of company order assessment, a superior membership function is brought forward to establish the element values in the fuzzy evaluation matrix, the rationality of the membership function is proved and an example with the fuzzy evaluation matrix built by this membership function is given. The company order evaluation index system using fuzzy comprehensive...
To solve the problem in risk evaluation method for project risk, this paper proposes a fuzzy theory model for project risk evaluation based on the project risk factor pool. The model solves, to some extent, the problem of how to analyze and deal with the widely existing fuzzy in risk evaluation, so as to provide a quantitative basis for correct risk assessment and to provide the decision makers with...
Project investment decision-making system is a typical grey system which has the characteristics of some information uncertainty. This thesis tries to combine organically grey system theory with AHP. It computes judgement matrix and builds model through weighted grey relevancy degree, which provide an efficient decision making pathway. Grey relevancy analysis method is used to handle with power project...
There are two principal ideologies in present digital library evaluation model. Divarication between them demonstrates the immaturity of evaluation research to some extent. To resolve such divarication can't only rely on the surface reference and complement from each other, but explore the intrinsic problem of divarication, then we can get ride of constraints and re-building a brand-new evaluation...
To overcome the shortcoming of the methods of the real estate investment risk assessment used today, which usually fail to solve the high-dimension data, an improved PPC model was proposed. By using the Projection Pursuit based on real-coded genetic algorithm, the method evaluates the merits of the investment programs. The real-coded genetic algorithm was applied to finish the global optimization...
Project review is always the key link of the Science and technology fund project management. Project review is a complex work which involves many factors. The final evaluation result is always influenced directly by the definition of various evaluation indexes and the corresponding weight. This paper mainly studies the judgment of the experts' ability and the establishment of the project evaluation...
The tolerance and non-stability in financial indexes make changes to other sub-systems like human resources, economics, factory productions and etc. Having underling knowledge and a model to simulate such systems obtains a fine vision to estimate further and calculate hard-decision making tasks before execution like: dept from banks, cash injecting and insurance services. Using Neuro-fuzzy networks...
In this paper, an evaluation index system for transportation scientific and technological projects evaluation is built, which composed of three categories and two levels indexes. The weights of indexes are determined by AHP method. Final scores of projects are calculated by grey evaluation method based on reformative triangular whitenization weight function. The evaluation index system and evaluation...
There is a rapidly growing interest in corporate social responsibility (CSR), especially in the current global financial crisis. We briefly review the development of CSR and point out in China the research is quite frequently immature and heavily qualitative. To facilitate the development, we propose a quantitative way to measure CSR and formulate CSR in a multiple objective portfolio selection model...
Molecular motors can be considered as biological molecular devices that are indispensable agents or machines for movement in living organisms. The most common motor proteins are Myosin, Kinesin and Dynein which are responsible for nanoscale cellular and molecular movement. In this work, the above mentioned protein molecules have been subjected to structural and sequence analysis, modeling and molecular...
This paper examines the forecasting of value-at-risk model. We explore and compare two different possible sources of performance improvement: asymmetry in the conditional variance and fat-tailed distributions. The HIS stock index futures are studied using daily data. Our result suggest that for asset returns which exhibit fatter and volatility clustering, like the HIS stock index futures, the VaR...
The number of seeds per pod is an important determinant of yield. New clues of yield and seed quality improvement can be provided by studying the relation between the developmental patterns of floral organs and seed production. In this article, a probabilistic model of plant inflorescence fertility is presented. From a biological point of view, seed development can be viewed as the combination of...
To handle the uncertain multiple attribute decision problem that the decision index value is hard to define accurately, this paper studies on the hybrid multi-attribute decision model of grey target when the index values are real number, interval number and triangular fuzzy number which exist together. According to the basic connotations of grey target decision and uncertain decision information,...
In order to make better the ecological environment, the assessment of ecological compensation is necessary and important. In this examination, the assessment means with Analytic Hierarchy Process (AHP) about the ecological compensation is analyzed and the indexes with ecological compensation are characterized, which make the AHP meaningful to evaluate the ecological compensation and make sure the...
A modified GM(1,1) model is constructed by producing new data sequence with the method of transforming every datum of raw data sequence into its n-th root. It is demonstrated that the property of the modified GM(1,1) model is superior to GM(1,1) model by numerical experiment. Moreover the modified model is applied in the prediction of fruit price index in China. The actual results also show that the...
In order to describe the tree topology more efficiently for modeling and biological calculation, a ternary tree data structure is introduced in this paper. The data structure of a ternary tree and the topological structure of a real tree constitute a mapping, which presents the biological properties of plant axes and the relationships among plant axes of different tiers. The simplification of tree...
Evaluation for urban sustainable development is very significant to improve the future development of urban. The analytic hierarchy process (AHP) is very suitable for evaluation of urban sustainable development. In the study, AHP is applied to evaluate urban sustainable development. On the basis of analyzing the evaluation indexes, evaluation model for urban sustainable development is constructed...
Both Vague sets theory and Fuzzy sets theory were often used to handle fuzzy information. The two theories had their own merits and demerits. Using fuzzy sets theory, the nonlinear mapping relationship of the fuzzy system could be depicted much better by changing (except ?? = 1 and p = 1, which become linear model) ?? (optimization criterion parameter) and p (distance parameter), although only two...
