Abstract: In order to solve the problem of multi-attribute group-decision making with the elements of evaluation matrix are intuitionistic fuzzy sets, this paper offers corresponding TOPSIS models based on the information entropy weights and examples to be verified. The examples show the feasibility and effectiveness of the proposed models.

Abstract: With the continued growth of social network users, nearly all the OSN (Online Social Network) providers replicate users’ data to different server nodes in order to ensure high reliability. Unlike traditional web applications, OSN represents a different class of data system that most of the data is based on friend relationship. In this paper, we propose OSL (Online Social Locality) algorithm, an online optimized strategy of data replicas based on social locality. This algorithm can decide the server node the replicas should be saved, and it improves system performance significantly.

Abstract: The general goal of the course of network engineering training is to develop the students’ talents of analyzing, designing and configuration or operation for network engineering projects. Some teaching experiences and effective approaches are introduced in this paper. This training course is organized with several specialized LAN based network tasks and students are divided into groups which should finish all the tasks. The idea of CDIO in engineering education is also adopted during the training. The result shows these approaches perform well in this training course of network engineering.

Abstract: The issue how to make scientific decision to avoid IT risk is one of the hot topics recently. IT governance models have been proposed are so general those they are unable to provide actual guidance for implementing informatization. The paper proposes a new model based on Evaluate-Direct-Monitor (EDM) model of ISO/IEC 38500 standard. An index system and prototype for decision support are proposed with the study of three stages in information system lifecycle. As a case study, an instantiated decision support index system is developed combining with specific application requirement.

Abstract: For the exigent requirement of short-term air traffic flow optimized dispatching, this paper analyzes dynamic behavior and network flow algorithm of short-term air traffic flow management, presents evacuation based ST-TFMP dynamic network flow algorithm, builds ST-TFMP GRNN model. The model is verified by simulation experiment, the results show it is feasible. The model improves precision of short-term air traffic flow management, saves time and cost, and it also actualizes the intelligence short-term air traffic flow management.

Abstract: It expounded the design quality connotation, product generalized quality was “the integrated embodiment of product function and performance”, the generalized product quality and the whole function and performance are equivalent. Clearly it made the design quality concretized into the product function and three performances. Expounded the concept of product design quality control, analyzed the influencing factors of product design quality, formed the design idea of quality control; aiming at the existing problems of traditional product design, established design quality control preliminary model by applying systematic design theory.

Abstract: With the development of computer, networking and automation technology, mining information technology becomes more intelligent and more integrated. This paper establishes a smart mine system in one mining enterprise of East China Mineral Exploration and Development Bureau. By adopting service-oriented architecture, smart mine system reuses the existing function modules and integrates the data through Web service to form a comprehensive service system to solve information island problems, which helps to facilitate production, operation and management of mining enterprises.

Abstract: The development of information technology has brought rapid changes to the industries, thus causing serious impacts on small and medium enterprises (SMEs). This study treated the employees in SMEs as the subjects to probe into the effects of vocational training and innovation management model on corporate operation performance when SMEs implement the enterprise resource planning (ERP) system. According to the empirical findings, the employees suggested that ERP implementation is the most important. Through project preparation, business blueprint analysis, technical realization, final preparation and effective support, operation performance can be fulfilled.

Abstract: This thesis puts forward a reconfiguration approach of mixed-model assembly line on the basis of adding equipments against short-term and violent change of demand. This approach makes uses of equivalent transformation of task volume to judge whether the capacity of current assembly line can satisfy the demand according to delivery time, and gives equipment configuration of completing the order by adjusting assembly line structure. Research results show that the shortage and excess of assembly line capacity as well as equipment configuration is different when order changes. The approach proposed in this thesis can be directly adopted as the scheme of mixed-model assembly line and referred to other capacity adjustment schemes, such as balancing the mixed-model assembly lines and cooperative manufacture.

Abstract: Spatial data fusion is an important method of spatial data acquisition. The aim of multisource spatial data integration and fusion is to improve the information precision and information's utilization efficiency. Vector and raster are the two main spatial data structures. This article discusses vector data fusion from of data model fusion, semantic information fusion and coordinates unification, reviews the main methods of raster data fusion and discusses the key technologies of vector and raster data fusion, and proposes the future developments of spatial data fusion technique.
