Abstract: The extensive application of information technology in all walks of life, extend the space of electronic commerce, commercial banks are also under various pressure. In recent years, because of the wrong operation brings huge economic losses, the risk to commercial banks in the management process is more and more complex. In the 21st century, the commercial banks have made great adjustment in the management process, during the exchanged system period, it is very easy to cause the risk. So China commercial banks began to pay attention to risk management in the management process. In the process of bank risk management , the application of information technology has an important role.

Abstract: After the development of decades cloud computing has landed from the cloud and formed a certain scale. Successful examples of the use of cloud computing to reduce operational costs attract many companies. But the comparison for price of cloud computing services and self-built server is not clear and hidden costs of cloud computing services is also not clear. This paper will compare the cost of cloud computing services and self-built server price and analyzed the hidden costs for users as accessing cloud computing decision-making.

Abstract: With more and more public attention and rapid development of computer and information technology, it is necessary for comprehensive games being equipped with information system. Venue Result System (VRS) is the core system in communication and information system of the Comprehensive games. In this paper, the existing problem and deficiencies in current information systems used in important games which are held in China or other countries are analyzed. According to the building and developing experience of information systems used in comprehensive games in many years into full consideration, the system is analyzed and designed by means of software engineering and then there are the overall technology framework of the system, different functional subsystems and the mechanism and flow of data interaction.

Abstract: Based on mass real data with the method of statistical experiment, this paper attempts to take the winning rate, annual rate of return and net profit margin as the management objectives for the comparative analysis on the strengths and weaknesses of the four systems of RSI, BIAS, KDJ and W&R among the securities trading software through testing, the results of which show that RSI expert system is the best one with its overall testing results superior to other anti-trend expert systems (MA, MACD, MTM). So it is suggested that investors should choose only RSI expert system.

Abstract: Compared with the expressway, most of the traffic flow in urban road network can be denoted as interrupted traffic flow. Based on the current employed equipment for traffic flow collection and traffic signal control in urban roads, different types of traffic flow in urban roads are analyzed with the traffic flow arrival/departure model in transportation engineering. Mathematical models complying with traffic flow changes are utilized to match the traffic flow in both entry and exit road blocks, thus, enabled the automatic detection of traffic incident. This algorithm provides a measurement for the automatic judgment of urban road congestion and the expansion utility of intelligent transportation facilities in urban areas.

Abstract: With popularity of Internet technology in business trade, and the platform of electronic commerce information services has become key factor in the business trade information management, which increase business trade opportunities and improve the international competitiveness under global economy integration and information society development. In this paper, the basic conceptions and forms of economical commerce system are firstly analyzed with the ways of material collection. It mainly considers the structure of enterprise economic management, deal management, finical management and enterprise culture .The paper also discusses the existing problems in developing economic commerce period and offers economic management strategy .It is necessary to make transform and innovation on enterprise management for the development of traditional enterprise.

Abstract: The article is research on the influence of urban lane occupied for the road traffic capacity. Under the condition that the density of urban traffic flow is big, and it‘s successional, we consider the quantity of vehicle is continuous. Through analyzing the dynamic changes of the road traffic capacity and its influencing factors after accidents, we can get reasonable suggestions of reducing the length of traffic jam. First we establish a flow-speed-density model to describe the dynamic changes of the road traffic capacity. Then we can compare the traffic flow to the electric current according to its continuity. So the upstream traffic flow and the traffic capacity of the accident cross section are equal to the charging current and the discharging current. And the vehicle queue is translated to the voltage of the charge-discharge capacitance. We can get the length of the vehicle queue by the formula of the capacitance voltage approximately. Finally the correction coefficient is introduced. In conclusion, the road traffic capacity is depended on the distance from the upstream intersection and the lane that the accident happened on and so on. Meanwhile, if we don’t solve the accident timely, the length will rise sharply. It will cause serious traffic jam. So we suggest relevant departments timely deal with the accident, evacuate the traffic, and prompt drivers to change lanes in advance.

Abstract: Ith the method of empirical analysis, based on the huge amounts of real data opened by securities market, through testing the expert system of securities trading software MTM, MACD and MA, with odds, annual returns and net profit margin as management goals, statistical theory as research basis, comparatively analyzed the advantages and disadvantages of the three systems. Except for annual transaction times of number, MA expert system is slightly better than the MACD expert system; while MA expert system, no matter in odds, net profit margin or in annual returns, trading opportunities, is better than that of MTM expert system in all-round way.

Abstract: The capability planning is a fundamental task when designing a Weapon System of Systems (WSOS). Uncertainties exist when building WSOS. It is difficult to select the most appropriate alternatives under the background of system operations. The programming of capability of WSOS is a multi-criteria decision-making problem. To resolve this problem, a scenario-based multi-criteria decision-making methodology is proposed. Scenario describes the future situation may occur, and also presents the uncertainty of reality. In this paper, scenario was modeled by the key variables in which experts and stakeholders are interested. TOPSIS was also improved based on multiple scenarios. Finally, the method is validated by an example of armored weapon systems.

Abstract: The emergency plan of high-speed railway plays an important role in guiding railway emergency management, the quality of which will directly affect the effectiveness and efficiency of emergency and rescue. Aiming at characteristics emergency plans of high-speed railway in mountainous areas, the evaluation index system of emergency plan of high-speed railway in mountainous areas is proposed. Based on the index system and intuitionistic fuzzy sets evaluation matrix, the scoring function value method is used to evaluate the index system. This paper uses the entropy method to assign weight to the index system, and finally take the emergency plan of high-speed railway from Guiyang to Guangzhou as an example to demonstrate the rationality.
