Abstract: Utility monitoring system plays a vital role for consumers in domestic areas to identify their electric power usage, thus creates awareness, motivates and educates consumers about saving power consumption. This paper develops a monitoring system for electric power usage, designed consisting of a digital meter, display unit, microcontroller, auto-generated data-based logging and communication device. The system is in real-time structure which measures the power usage by hourly basis and displays the results in kWh every time in convenient and organized manner. The data-based logging feature enables utility usage information to be recorded in timely basis. An additional feature provided in this system is a notification module that send charges information corresponding to consumer’s utility usage. Consumers are able to be aware of the utility usage with the corresponding charges at real-time basis as well as capable to predict, control and manage their utility usage on daily manner. Eventually this system is beneficial for both parties which are the consumers and the utility provider.

Abstract: With the rapid development of wireless communication technologies, users could get many kinds of services and applications now. And as the number of users and the amount of traffic are growing, the contradiction between the infinite demand of users and the finite radio resources is getting increasingly apparent. According to this situation, this paper propose a radio resource allocation algorithm based on bargaining game theory for fourth generation long term evolution (LTE) system, with which the network could balance the situations of users in different classes and enhance the utility of users. The simulation results show that the proposed algorithm could allocate the radio resources efficiently and provide users with higher utility.

Abstract: The popularity of mobile communications and coexistence of heterogeneous access networks make it possible that the person can achieve the communication business with little restrict, which requires the support of ABC (always best connected) and the guarantee of users’ QoS requirement. For the property that the network status and users’ QoS requirements are difficult to get, this paper proposes an ABC supported heterogeneous access networks selection mechanism based on the particle swarm optimization based on adaptive diffusion and hybrid mutation in view of users’ preference, users’ cost and network providers’ income. The simulation result shows that this mechanism can not only satisfy the users’ requirements, but also maximizes the utility of both sides.

Abstract: The psychology of utility of the agent in government investment projects is studied from the psychological point of view in this paper. Combining the game theory with the deterrence theory, we establish the applied technology named deterrence game model which is used to predict the behavioral intention of the agent. Then according to the specific actions of the agent during the construction,we adjust to exert a certain deterrence which is expected to restrain and guide the behavior of the agent,which makes the whole process supervision of government investment projects under control.This paper demonstrates the effectiveness of the applied technology.

Abstract: he resource allocation is very important in DP, but it doesnt take into account the order of the time for distribution object, By using the DP, the main application of the one-dimensional theory of resources allocation, It view of the actual situation from college students exam time arrangement with utility theory, during the practice the dynamic planning will be changed and Gantt charts will demonstrating together, the original has practical significance is more obvious.

Abstract: Delivering recommendation services are the trend of the future, so Recommender System varied very vital and widely applied in e-commerce websites to help customers in finding the items they want. A recommender system should be able to provide users with useful information about the items that might be interesting to them. The ability of immediately responding to changes in users preferences is a valuable asset for such systems. In recommender system, a variety of methods have been emerged as the basis for recommender. However, existing recommendation methods have the limitation. To overcome this limitation, we will propose new recommender system by combining the existing techniques. So, we firstly give an overview of recommender system for the future researches.

Abstract: The paper analyzes the process characteristics of mechanical and electrical products' industrial design, and emphasizes that products' industrial design adequately use more methods in premises of considering more technology and other restrictions. The comprehensive method is more suitable for the industrial design of new mechanical and electrical products, which can truly achieve the human-centered design aim.

Abstract: To input rational customer requirements into engineering design process more effectively and improve product design quality and market response efficiency, this paper focuses on the interaction between market analysis and engineering design decision for the modular product. While many researchers have successful evaluated and optimized the design schemes, few, if any, have provided a bridge the customer selection and firms product development decision. After a review of the literature we introduce the flow of user-engineering design interaction including both maximize the utility of customer and the profit of the firm. On the user and market analysis flow, customer requirements are defined according to the target market, then the customer selection possibility link to the product attributes by utility function. Accordingly, the alternatives are corresponding to the module different product, and then using decision support problem method to search the optimal design parameters. Two design domains can share the design information and realize the cooperative design process by computer computing platform.

Abstract: Evaluation of vehicle combination property involves multiple attributes of both a quantitative and qualitative nature with uncertainty, and there is incomplete information in the assessment process .Evidential reasoning(ER) method is introduced to transform quantitative and qualitative information to uniform distribution .With the ER ,the general values of assessment can be obtained through aggregating the lower attributes, then decision is made using utility theory. The example demonstrates the effectiveness of the ER method.

Abstract: The paper studies the adaptable capability of applications in mobile networks in the context of the optimizing the network resource usage. Based on a thorough analysis of applications’ adaptability, a unified utility framework is proposed to describe the resource requirement of applications and their adaptability. Utility functions of different type of applications are discussed under the utility framework. Examples for how to use the framework are also given. Simulation results show that the proposed utility framework can be used for optimizing network resources and can therefore satisfy the needs of more applications.
