The risk assessment is an important task in operational management. Since secondary system of substation(SSOS) is an important part to ensure the safe operation of the substation, close attention is needed to its operation risk causing power loss. According to past research, the difficulties of its risk assessment include complex relationship of secondary devices, and risk analysis of its impact on...
This paper proposes an improved cloud-element model for information security risk assessment. Combined with the characteristics of dynamic balance of information security risk, we propose the control means and uncontrollable factors as information security risk evaluation index. The method of constructing the sample cloud has been expatiated, and the correlation between the cloud droplet and the sample...
In order to effectively control the risk of software project and overcome the effect of lack data and human subjective factors in the traditional evaluation, the transformation of quantification and reduction of natural language is realized, so a new evaluation model is put forward. Based on the concepts of risk weight, expert trust, risk consequence and so on, we use the correlation coefficient to...
In the view of supply chain finance, the default risk of the enterprise not only exists within the enterprise, but also gets along with between two enterprises, which makes it more essential to evaluate the default risk of the whole supply chain. This paper addresses on the contagion of the risk between two enterprises, selecting the financing enterprises as the research object and taking two enterprises...
In this paper a bottom-up hierarchical real-time risk assessment approach based on risk propagation is presented. The approach calculates risks of services, hosts and network caused by attack processes in real-time. Risk index and risk status are used to quantify the risk situation. These two concepts are involved with three aspects of attacks: severity, certainty and successful possibility, and with...
According to the diversity of software development risk, the complication of evaluation indexes and the comprehensive evaluation hardly with the present evaluation method, the software development risk was divided into three grade indexes. 13 risk evaluation indexes were constructed based on the different stage of real situation in the course of software development. Based on the grey decision-making...
Using a cross-sectional logistic regression model and economic value added index, this paper explores the motive and value creation of mergers and acquisitions. The results indicate that an increase in market value and economic value added will increase a firm's likelihood to engage in takeover transactions because of high level of managerial ability and low agency cost, while increasing in asset-liability...
Based on Fisher's Linear Discriminant Analysis, the paper proposed an early warning model to predict the bankruptcy possibility for construction companies in China. Sample and variable set of the study came from 56 privately owned Chinese construction companies and their financial ratios, and 27 companies' crisis occurred during the period 2008–2009. Kolmogorov-Smirnov test was used to examine the...
For the fluidity of project, the paper exploits the evaluating model of its fluidity by the relationships of its fluidity and fund reclaimed time, quantity. Then, it develops the indexes of risk evaluation, as the yield standard criterion in fluidity of project, the indexes of project risk yield. So they are more reasonble for decision-making of project.
A new index system of commercial bank liquidity stress testing is set up after cluster analysis of R type. And then the index weight is determined by entropy method. Commercial bank liquidity risk is rated. Taking 14 listed banks for example, rating liquidity risk. The innovative feature of this paper: Firstly, observable indices replace unobservable ones, it is feasible for banks to ensure liquidity...
Value at Risk (VaR) is a commonly statistical tool to measure market risk. In this paper, a mixture method of APGARCH-M model and EWMA algorithm is applied to measure VaR of a portfolio. Empirical study using three stock index of shanghai stock market shows the mixture method is advantageous and accurate to calculate VaR of a portfolio.
In this paper, the gray relational analysis and 6 sigma of the FMEA method have been applied to enterprise applications quantitative analysis of risk factors on the basis of building enterprise application software risk index system. Using improved FMEA model and method which are based on gray relational analysis, this paper makes quantitative assessment and ranking for the risks of enterprise application...
The purpose of this paper is to investigate the risk measures based on general autoregress conditional heterostedasticity (GARCH) model in tanker shipping industry, to choose Baltic Dirty Tanker Index as study object. This paper applies Value-at-Risk model, widespread used in financial field, for measuring risks in shipping market. The parameters of the model are estimated by statistical software...
Tourism developing risk can lead to unsustainable development of tourism, so tourism managers should evaluate the risk of tourism development, and implement risk management. They should take some measures to prevent and resolve risk, which can promote healthy development of tourism. In the paper, the author applies grey correlation theories and group- decision AHP to evaluate the risk of tourism development...
The universal indicator system of water resources risk assessment has been built based on natural disaster risk theory, and it were disposed with rough set theory, which realized the attribute reduction to those indicators. Thus we can get target indicators in accordance with reality in the evaluation area and the weight of the indicators has been identified by subjective (Analytic Hierarchical Process)...
This paper expounds the basic content of Interrelated Tree Method, and builds the Interrelated Tree model of EPC project risk management; On this basis, the paper makes a risk list with the combining methods of qualitative and quantitative analysis and through the prediction and identification of the risk in the EPC project's whole process, and sets up risk assessment index system of all stages of...
The design phase is the key to the implementation of construction standards and industrial policies, but the basis of the control of construction project investments to achieve its sustainable development. How to accurately identify, measure, control and manage risk is a focus of risk management to architectural design enterprises. This paper identifies the common risk factors in the design, combined...
Ecological Risk (ER) refers to the possibility of reduction for its partial health, productivity, economic value and aesthetic value when normal functions of whole landscape have been intimidated by external environment. Ecological risk assessment is a key measure of ecological environment management. Assessing the ecological risk at regional scale has practical significance in strengthening ecosystem...
The global financial crisis in 2007 made the companies' competition environment and operation condition more hardly. As an important part of enterprise risk management, financial evaluation has also attracted more attention from scholars. The paper used PCA and logistic regression modeling comprehensively to create a listed company's financial evaluation model. It used PCA to reduce dimension of financial...
With the rise in coal price, the proportion of loss-making enterprises show an upward trend in China's coal industry. The paper uses Altman Z-Score model to measure financial risk of 19 listed companies in the coal industry in A-share market from 1995 to 2007. Empirical results show that Year-Based price index of coal price has a negative correlation with the financial risk but not significantly,...
