There are some small-sample cases in economic forecast, for lacking of quantitative information, in which it happens that some given forecasting method fits well while behaves badly in forecasting, while to the contrary, the situation behaves well when we make the combination of both qualitative and quantitative methods in forecasting. The concept of risk of forecasting is defined, as well as the...
Nature's Real Estate such as water, minerals, oil & gas, and coal is the precious gift available for the welfare of mankind since time immemorial. In spite of the efforts initiated by many countries in the development of non-conventional energy resources, it is too early to visualize that the gap between supply and demand of energy could be bridged in the near future. With this backdrop, the policy...
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...

With the development of computer and network technology, the network environment provide a full range of information support for accounting information system to, network Accounting become new area of accounting development. But network accounting is facing much risk, and would take great danger to the accuracy and security of accounting information. SO, risk analysis of network accounting and proposing...
In this paper, proposed ISM to the risk analysis of supply chain under the risk identification. Drawing the structure of the risks, get the interactive relation between different risks; finally provide reference to the management system of project risk and theoretical support for quantitative analysis followed.
An improved model for portfolio selection based on particle swarm optimization with escape velocity (EVPSO) algorithm is proposed. Firstly, the predilection coefficient is introduced to the model to make the investor choose the invest project according to their preference and find the balance between the invest income and risk conveniently. Secondly, the EVPSO algorithm is applied to the model to...
Since the reform and opening up, China's economic rapid development. Energy, transportation, communications and other infrastructure buildings have an urgent requirement, but it is difficult to rely on government finance to meet the demand, so we must broaden the investment and financing channels, and BOT model is one of the best. As a foreign investment and private capital to build infrastructure...
Cost-benefit analysis has long been used in decision making about public health and security. Frequently, risk and uncertainty are involved, and benefit and cost are not evenly shared by all stakeholders in the activities where public welfare is concerned. The result of cost-benefit analysis may be controversial because it does not consider the conflict of interest among the stakeholders. In this...
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...
When a Petrochemical end-user builds a new plant, almost all the end-users have specifications with a preferred vendor list. For the competition the end-users put more than one brand on the preferred vendors list. The Engineering, Procurement, and Construction (EPC) contractor will buy the cheapest brand of the vendors list. This means selection is based on minimizing the Capital Expenditures (CAPEX)...
The previous discuss on the Chinese bank efficiency always neglected the risk factors effects, and there is little research to investigate the relationship between risk and efficiency in domestic study for banking industry. This paper analyzes the technical progress efficiency of the Chinese banks during 1996 and 2006, and compares the effect differences between the risk-adjusted model and the model...
This letter describes a new perspective on balancing system security level with cost for real-time operation. Security level is quantified using risk, which provides that security may be optimized. A risk-based multiple-objective (RBMO) model, considering security and economy together, is compared with the traditional security-constrained OPF (SCOPF) model. A six-bus test system is used to show the...
