During the construction project practicing, contractors will face all kinds of risky factors. This paper analysis the risk factors on base of the characteristics of contractors, establishes risk index system, using the fuzzy comprehensive judgment to calculate the risk degrees, Each risk actor is estimated in the aspects of probability and the influence. The weight of the risk actor is calculated...
With the rapid development of industrialization and urbanization, security situation becomes more and more serious in China. Many cities have established security systems in order to maintain social stability. Although various security facilities have played a positive role in the field of social security prevention, there are some defects with poorly designed and personnel protection, physical protection,...
Nowadays, with the rapid development of industrialization and urbanization, national security situation become more and more serious. Although various security facilities have played a positive role in the field of social security prevention, there are some defects with poorly designed and personnel protection, physical protection, and electronic protection formation non-integration. The effectiveness...
Agent construction system is a new project management mode to meet the need of modern engineering construction, and is an innovation of government-invested engineering management mode. There are some positive aspects and some risks during the implementation .This paper analyses the risk factors based on the characteristics of agent management projects, establishes risk index system, using Entropy...
With the security industry developing rapidly and the number of security systems increasing continuously in recent years, security systems provide a positive effect on society security in China, but many of them became vulnerable or even useless because of the problem of irrational allocation of resources. In order to evaluate security system efficiency to avoid these problems, the hierarchy structure...
It is no doubt that design risk management(DRM) plays an important role in safety, quality, schedule and cost of the large-scale construction project, with complex and special surroundings and control objects, more efficient and quantitative methods are urgently required to analyze and predict the focus of DRM which need to be controlled. Simplifying and processing these complex parameters in DRM...
Software risk management is an important approach to obtain trustworthy software. In this paper, entropy was applied to uncover the reasons of chaos and gave the mechanism of risk management in development life cycle. Information entropy was introduced to assess risk uncertainty and a three-dimension risk assessment was obtained through a questionnaire survey. The finding of the study shows the necessity...
In this paper an information entropy assessment measure of supply chain system risk and a decision-making method based on combined fuzzy weight and entropy weight in which the input of score matrix are triangular fuzzy numbers are proposed. The individual's intuitive attitude toward risk is just reflected by the fuzzy weight measure of risk. An index system under supply chain risks is established...
To encourage further development of catastrophe (cat) bond, understanding the causes of cat bond premium puzzle is necessitated. Considering the property of entropy to measure uncertainty, this paper establishes an entropy model about risk assessment in catastrophe bond investors' decision making. Moreover, this article analyzes the model and compares relative influence through simulating actual behavior...
The risk of maritime traffic is an issue to express the uncertain information. In order to assess the risk of traffic environment at port, the theories and methods of unascertained mathematics were introduced. Considering the unascertained characteristics of traffic environment at port, the weight of risk system coefficients was determined and an unascertained quantitative model was established for...
Because there are lots of random and fuzzy uncertainty factors in power system, the certainty model used to be adopted in reliability research were not reasonable. But cloud models theory is a powerful tool to convert numerical quantitative analysis to conceptual qualitative analysis. In this paper on the basis of introduction of cloud models, the parameter and load cloud models in actual operation...
With the need for improved performance in the construction industry and increasing contractual obligations, the requirement of an effective risk management approach has never been more necessary. In this paper, a new approach to construction project risk assessment based on rough set and information entropy is proposed. Firstly, the construction project risk evaluation index system is established,...
