In order to control risks and facilitate effective decision-making, the relations among risk chains should be systematically analyzed, which is a very difficult process. The aim of this research is to understand the connective generating structure of risk chains and plan problem solving accordingly. Therefore, in order to select the analysis method, association rule mining was applied. From the extracted...
This paper presents a hybrid intelligent system (HIS) for risk assessment based on unstructured information. The generalised structure of a hybrid intelligent system (HIS) and its implementation in various information systems are described using a number of case studies. The definitions of risk and unstructured information are discussed in the context of hybrid intelligent systems to highlight potential...
The application of virtual reality technology is a trend that holds considerable promise as demonstrated in many applications. This technology includes the means to visually integrate and interact with diverse multidimensional data in 3D and time context, extend real-time decision-making into mine maintenance, implement virtual mine-planning simulations, training simulations, and risk management....
The construction of communication network project is a process with a great amount of investment, long period, high technical requirement and complex system. Unknown factors, random factors and fuzzy factors are abound in the process and are changing constantly, the resulting risk directly threatens the successful implementation of project. The risk of communication network project enlarges as the...
The assessment index system of lightning disaster situation is established in this paper, based on the actual data of lightning disaster and combined with the value standard such as current population, economic and ecological factors. The calculation model for comprehensive evaluation of losses in lightning disasters is given by using the Analytical Hierarchy Process (AHP). It can provide scientific...
As an important character, adaptive decision-making is not only essential for individual decision-maker, but also for group decision-maker. This paper focuses on entrepreneurial team's risk decision-making process based on group learning. Firstly, this paper analyzes the group learning mechanisms of entrepreneurial team's risk decision-making process, and divides the process into two basic stages...
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.
The risks associated with making decisions based on poor-quality information are quite high. Consequently, the management of information quality (IQ) and the quality of associated information management processes has become critical for healthcare organizations. An important first step in managing information quality is the ability to measure the risk of information products based on the quality of...
Establishing high performance cooperation in the peer-to-peer (P2P) network architecture is a fundamental and challenging research area currently, due to peer anonymity, peer independence, high dynamics of peer behaviors and network conditions, and the absence of an effective security mechanism. Most assessment methods based on trust or reputation have some remarkable innate drawbacks, for some presumed...
Nowadays, the environment risk of mining area is a very serious problem. And mining area environmental impact of a variety of uncertainties, from the engineering point of view can be divided into land pollution, water pollution, air pollution, noise pollution and solid waste pollution. In the paper, an evaluation index system of mining area risk is established by using the triangular fuzzy number...
This paper proposes a fuzzy TOPSIS method based on Vague sets. The relationship between the fuzzy TOPSIS method and fuzzy weighted average (FWA) is also discussed. An example including an application to IT project risk assessment is investigated using the proposed fuzzy TOPSIS method. It is shown that the proposed fuzzy TOPSIS method performs better than the other fuzzy versions of the TOPSIS method.
In view of the shortage of e-commerce sites for data mining system, Web data mining system framework based on mobile agent is proposed in this paper. In advantage of the independency, mobility and intelligence of mobile agent, the search process and the recommendation of the entire commodity have a higher timeliness and accuracy. Businesses can apply the information to analyze and predict future behavior...
A new method is proposed to solve multiple attribute group decision making problems with linguistic assessment information. In the method, the two-tuple linguistic representation developed in recent years is used to aggregate the linguistic assessment information. According to the traditional ideas of technique for order preference by similarity to ideal solution (TOPSIS), the optimal alternative(s)...
The project risks can be evaluated by Analytic Hierarchy Process however this method is not flexible. Based on the introduction of Gray System Theory and the improvement of Analytic Hierarchy Process, Gray Analytic Hierarchy Process was proposed in this paper to evaluate project risks effectively. The basic steps of Gray Analytic Hierarchy Process were given, and the example, using this method to...
Highway construction progress risks not only influence the development of an enterprise, but also have a great impact on the national overall strength. This paper attempts to analyze construction progress risks of highway qualitatively and quantitatively from the perspective of theory and practice. The weight of each progress risk index could be obtained by using the analytic hierarchy process and...
This paper gives a new reasonable decision making method based on IAHP and DEA. This method uses DEA (CCR) to gain the sequencing weights of all items in every class. The interval weights through IAHP are considered as the weight constrains in DEA. It combines with IAHP and DEA to get the final weights for synthetically sequence. An example of practical application is given to show the effectiveness...
This paper aimed to establish a method of risk assessment based on grey decision making. Based on the characteristics of IT projects' risk, the paper defined five main factors that influence the success rate of IT projects and mixed the total risk to a matrix. By applying the grey relational analysis to measure the matrix's grey relational grade, in terms of which we can establish the evaluation guideline...
Logistics operation risk is one of the main and internally-controllable risks for a third party logistics service provider (3PL). According to the identified relationships among objective risk, estimated risk, risk preference and risk control, this paper presents a mechanism to control logistics operation risk and a control model for 3PL. The existence of the optimal solution is verified. Finally,...
Taking into account the vital importance of investment risk evasion, this study focuses on avoidance of risk in a multiasset and multiperiod dynamic investment described by an accumulated wealth stochastic process. On the premise of risk evasion, the optimization of investment decision-making has been discussed in this paper. We first extended Kelly strategies and fractional Kelly strategies (FKS)...
Supply chain alliance as a new model of enterprises business cooperation, fair and reasonable mechanism of profit allocation is related to its success or failure. Based on the research at home and abroad, this paper applied fuzzy decision theory into improving traditional Shapley Value and introduced the parameter of integrated corrected factor to present the influences of risk and capital appreciation...
