This paper combines rough set method and evidential reasoning method, using evidential reasoning approach as a comprehensive settlement on the one-sided defect of rough set data mining method and using rough set method as a comprehensive settlement on the subjective defect of evidential reasoning method. Thus we construct a scientific and rational firm evaluation model. Firstly, model uses the attribute...
Based on the TAM model, the objectives of this study are to explore organizational roles' differences in e-learning acceptance. A survey taken from 10 financial companies which had implemented e-learning system shows that managers perceived usefulness in e-learning are stronger than perceived ease of use and employee perceived usefulness and ease of use are stronger than managers. The perceived usefulness...
There are two main quotation mode in current bidding, which are without base price and compound base price. Bidders should bid accurately and reasonably to win a bid. Based on game theory and the characteristics in bidding, this paper constructed bidding price game model of without base price and bidding price game model of compound base price to provide evidence for bidding decision. Relevant factors...
The evaluation for current situation of ecological compensation is significant to strengthen the system of ecological compensation. In the study, the method based on the combination of analytic hierarchy process (AHP) and fuzzy theory is proposed to evaluate ecological compensation. Firstly, evaluation indexes for ecological compensation are described, and the evaluation model of ecological compensation...
Considering the uncertainty of information, the paper puts forward an improved grey dynamic programming model. After that, treating profit value as positive interval grey number, the paper researches on dynamic programming model, and we could get the optimal strategy after solution by means of defining standard interval grey number. Furthermore, as we can not make the judgment of standard interval...
Intellectual capital in the context of knowledge-based economy is important means of the enterprises survival and development. According to analyze constituent elements of intellectual capital, the index system was proposed by human capital, management capital, technology capital and market capital, index weights were determined by using AHP, the comprehensive evaluation model was established by using...
Real estate investment is a high-risky and complicated activity. It is necessary to utilize scientific methods when deciding to make these complicated investments, which probably result in large financial losses. The analytic network process (ANP) can be applied to produce a comprehensive analytic framework for solving the real estate investment decision-making problem. Based on this theory, considering...
It is important content that the studying connective stability among the stability studying of the large-scale interconnected systems. The many results recently have been given for the normal systems, the studying result of the singular large scale systems, however, is a little. The paper discussed the connective stability of a kind of nonlinear singular large-scale dynamical systems by means of singular...
In the paper, the k-switching reachability set Rk of a single-input positive switched system is introduced, and conditions for the chain of this sets {Rk; k isin Nopf}, to stop increasing after some finite index k are given. For the special class of positive switched systems, which commute among n single-input n-dimensional systems, sufficient conditions that ensure that the n-switching reachability...
In the multi-objective evaluation process for real estate investment, because of the uncertainty and incompleteness of evaluation information, deciding its gray. Therefore, the gray comprehensive evaluation based on gray system theory has feasibility. In this paper, we establish the gray comprehensive evaluation model of real estate investment according to the impact of real estate investment with...
This paper proposes a multiobjective dispatch model to operate hydroelectric power plants. The model is composed of two algorithms that are based on Genetic Algorithms. The first algorithm is used for the static dispatch of generating units and is aimed at maximizing plant efficiency on an hourly basis. The second step is a multiobjective technique for the daily operation of generating units. The...
Business objects represent the key concepts that a business needs to operate such as people, services, products, etc. but transforming these objects to and from existing data models can be difficult. Business objects have traditionally been represented in a backend data store using relational databases, and techniques for transformation must work with these stores. But such access may violate the...
