Establishment of an improved model for assessing criticality of waste in maintenance operation strongly supports the creation of sustainable manufacturing. However, contribution of previous maintenance engineering studies to above issue is very limited. If any, it is very few intended to create a model for ranking criticality of maintenance waste using risk management tool. In spite of the fact that...
High risk and high profit are the remarkable characters of enterprise technological innovation. The higher innovation degree is, the higher uncertainty will be. It is very important to analyze entirely all kinds of risk factors which can influence technological innovation and evaluate the process of technological innovation. In this paper, based on the index system of enterprise technological innovation,...
In this paper, on the basis of previous studies derived the local government debt risk assessment model, established risk prediction methods by using BP artificial neural network model, and analyzed this method through an example. So provide a set of scientific method to evaluate the local government debt risk and predict the short-term risk. This is useful for adoption effective means to control...
From the broking out of U.S. substandard loan crisis and the closing down of commercial banks ,we can see the important reason of suffering heavy losses is that commercial banks did not properly assess a series of facing risks. At present, China's commercial banks risk analysis is still in the traditional objective qualitative analysis phase, as for risk quantification, especially comprehensive evaluation...
The article examines daily market index data of China stock markets from 1998 to 2008, and analyses fluctuation link trend between two regions' stock markets. Through Johansen co-integration test and Granger causality test, the paper finds the link between Shanghai and Shenzhen stock markets and Hong Kong stock market has become more closely linked and integration trend is remarkable. The strong relevancy...
Under the opening economic circumstances, evaluating the risk of cross-border capital flow has special significance. For effectively evaluating the risk associated with capital flow, a new evaluation index system of risk is created on the basis of fourteen influencing factors. The analytic hierarchy process is used to determine the weights of indexes and four-grade risk comment set is adopted. Using...
By means of the ARCH (Auto-regressive Conditional Heteroscedasticity) and its modified models, this paper presents an empirical analysis of the volatility heteroscedasticity and the resilience to external shocks for China emerging stock market in the past three years based on the stock index of SSE180, SZSE40, Coal/Petroleum and Finance sectors. The results show that the fluctuation of SSE180 index...
A new quantified model of evaluating the economic risk of technology innovation project which based on Monte Carlo simulation technology has been proposed in this paper. That is use three point which are maximum possible value, minimum possible value and the most possible value to estimate the risk variable. Using AHP method, variable weight of delivered and extended risk to determine the weight of...
In stock markets, the price is fluctuating around its average value with the time being. One of the volatilities is the variance heteroscedasticity. It is found that auto-regressive conditional heteroscedasticity (ARCH) model provides an alternative approach for the simulation of stock heteroscedasticity. In this paper, the application of ARCH and its modified models is presented for the risk analysis...
