Abstract: In order to solve the limitation of the research about enterprise evolution modeling and simulation, the idea of applying complex adaptive system theory and agent-based computational finance method to the enterprise research was proposed. Secondly, an applied model of Agent-based enterprise evolution was built. Finally, the simulation program of enterprise evolution based on swarm was built, which simulate the dynamic competitive behavior and evolvement of enterprise, the result of the simulation was analyzed.

Abstract: The evaluation of grid communication resources investment plays an important role in planning and investment decision-making. This paper first develops a comprehensive evaluation index system by combining the practical work of grid communication investment with the significant benefits, such as communication technology upgrade and service capacity building. Furthermore, based on this index system, we construct an evaluation model by screening effective alternative based on the method of DEA (data envelopment analysis), moreover, we determine the index weight by using improved grey correlation degree method. Finally, we provide an example of Henan Electric Power Communication Company to examine our model. The results show that the model is feasible and effective.

Abstract: The variation of futures price is affected by a lot of factors. It is a challenge to predict the price’s trend. In this paper, we apply random forest technique to predict the type of K-line in next day. First, we empirically select nine technical indexes as input variables or features. Then, these features and the associated class label, i.e. the type of K-line, are used to construct RF classifier. The experimental results demonstrate that RF is effective and can be used in the trend prediction of futures price.

Abstract: Starting with synergetics and systems engineering theory, this paper proposes a model for measuring the similarity among allocated modules of Project Portfolio Allocation at the level of project. Utilizing concepts like order parameter of fit, good-of-fit for Project Portfolio Allocation (PPA) and similarity among allocated modules, this paper uses the value of similarity among allocated modules of PPA to reflect the similarity among allocated module which provides a useful analytical methods for project portfolio allocation management in large state-owned firms. Finally, the effectiveness and feasibility of the proposed model is demonstrated and validated by a case study.

Abstract: To take a wonderful understanding of design process, a modeling method based on colored hierarchical timed Petri nets and a model for a typical process of product design using this method are introduced. Then, aiming at some key issues, the model are simulated by CPN Tools and the results are shown in the paper according to which some convictive conclusions are drawn which indicates the method introduced is valid and reasonable.

Abstract: Establishing the evaluation index system, from their own investment capacity, corporate external financing capacity of the two dimensions, using resultant weights and TOPSIS method for comprehensive evaluation of investment capacity of the power enterprises. Set a power company for example, results show that, the evaluation results are in line with the actual investment capacity situation of the power enterprises, the established evaluation index system and evaluation model has better applicability.

Abstract: Based on the traditional theory of the intelligent systems, as well as the present study on intelligent tourism, Tourist Satisfaction Index model of Intelligent Tourism is put out in this paper. With the data collected in Nanjing, statistic materials suggest that two variables, Perceived Quality of the Intelligent Tourism and Intelligent City, play the most important roles in tourist satisfaction of intelligent tourism. The further analysis reveals that the factor under Perceived Quality of Intelligent Tourism, including Intelligent Transportation, Public Service Platform, Intelligent Hotel and Intelligent Travel Agency, as well as the factors under Intelligent City including Intelligent Governance and Intelligent Environment are the most important factors in the model.

Abstract: Compared with the general power engineering projects, UHV projects have characteristics of large construction scale, wide radius of management, long management chain and many units involved. Therefore, UHV projects have many financial risks which are different from general power projects. Identifying and measuring risks of financial management in the UHV project is of great significance to avoid important financial risks and improve the efficiency of project financial management. After combing the present situation and characteristics of the UHV project financial management, we use the “three whole” to identify UHV project financial risks from an all-around point of view. Then each importance score of the risk is obtained by expert scoring method so as to divide all the risks into 3 groups, significant risks, important risks and commonly risks by clustering analysis, which can provide the basis for optimizing UHV project financial management mode in the future.

Abstract: For a long time, grassroots power supply and distribution of enterprise business management information system is mainly their respective construction, independently running, reaching the job site and then filled out, and came back the relevant information into the computer and stored in the relevant paper materials. Information fragment result in an information shield plug and is unable to provide a more efficient service. The use of management and distribution with an integrated operating mode is a good solution to these problems. In this paper, in terms of configuration, the product value allocation of internal resources, analyzes the advantage of use of management and distribution with the integration and concluded with one based on GIS construction application system platform will effectively improve the distribution network operation and management of business requirements, providing IT support for the operation of the distribution network using modern management tools, which will help improve the level and efficiency of the distribution network operation and management, improve customer satisfaction and customer service levels, improve customer reliability.

Abstract: There are two sides of system reliability parameters, such as basic reliability and mission reliability, for reliability requirement in the standard, with fine relevance and coordination. It reflects in the determination of the parameters and index and also in the prediction and allocation for basic reliability and mission reliability. It analyzes from mission profile, state transfer and data collection and process, defines the key elements for the analyses of mission reliability based on Agent simulation, and lays the good foundation for setting up a fine mission reliability simulation model of materiel system, analyzing dynamically mission reliability and making a perfect mission reliability simulation concept of materiel system.
