Putting investment in real estate or in stock? It is a hard decision for the investors to make. So based on the data from the year 1998 to 2007, this article sets up a gray-situation decision model, which shows that in the past 10 years the strategy of investing in real estate is the best, better than investing in stock and than investing in both simultaneously. This article believes that it is not...
There are some weaknesses in the traditional safety evaluation methods, such as, slow reasoning, low accuracy and so on, so thinking of a variety of factors which affect gas safety, a gas safety evaluation index system is built, which focuses on the state of gas, mine ventilation, gas monitoring, safety management and kindling. Combining the fuzzy comprehensive evaluation method with gray correlation...
The first and second layer factors of a host risk on the network is designed and a factor system of the network risk evaluation is built in the paper. To achieve the quantitative evaluation for host risk on the network, the improved AHP method is used as well as experiment is carried out. Finally, it indicates that this approach is able to quantitatively show the host risk on the network.
This paper proposes an optimal Var resource allocation framework for power transmission system in such a manner that both voltage profile and security margin for future operation is considered. The risk index is used to represent the uncertainty in this framework. The conception of Var gap is proposed to cover the voltage profile issue and the security margin issue when the Var allocation is performed...
The core of fuzzy evaluation on the safety of chemical industrial park is membership degree transformation. But the transformation methods should be questioned, because redundant data in index membership degree is also used to compute object membership degree, which is not useful for object classification. The new algorithm is: using data mining technology based on entropy to mine knowledge information...
In the word, lots of consumers choose to buy their commodity on the Internet, so e-commerce is playing an increasingly important role and its safety caused more and more concern. The success or failure of transactions, the confidentiality of client information, and e-commerce system stability are directly related to the safety of e-commerce. In this paper, we use the method for e-commerce security...
The AHP-Fuzzy assessment method is a combination which unifies the AHP method and the fuzzy mathematics. AHP can synthesize human's subjective qualitative judgment, form the weighting of each policy- making factor, and avoid appearing the logic reasoning fault in the complex decision-making question. The fuzzy mathematics, simulating the characteristic of human in making the judgment, is good at processing...
This thesis set up the comprehensive evaluation model of customer satisfaction degree based on Analytic Hierarchy Process. The validity of the models was proved with a practical example. The conclusion of evaluation can reflect the customer satisfaction degree objectively and offer clear decision-making references for Power Supply enterprises.
AHP is an important method of evaluation; it has been widely used in the decision-making. Contraposing it has the ignorance about Security in some decision-making field, this paper mixes the AHP and fuzzy synthetically evaluation,then designs a new evaluation method of the candidates' comprehensive quality. It offers a scientific and reasonable method of the evaluating college graduatespsila comprehensive...
Protecting the security of the dam is a vital problem for the reasonable use of the water resources, so it is important and meaningful to research methods of assessing the safety of dam for which is related with the national economy and the people's livelihood, and it is necessary to build a system to estimate the security risk of dams. The dam failure disaster risk is regarded as main researching...
Based on the ideology of "using the monitor data to reflect the production safety and using the risk analysis and safety evaluation methods to guide safety management to realize the objection of mine coal safety state warning and assistant decision-making support system", with Bofang coal mine of Shanxi Orchids Corporation's practical experience in safety state management, we set up a warning...
