Abstract: Enterprise network refers to the summary of relationships based on common social and cultural background and the basis of mutual trust, connected with information technology, and forged by a group of interconnected enterprise behavior actors and institutions in the process of sharing resources, exchanging resources, and delivering resources in order to respond to market changes quickly. It represents a new organizational structure different from traditional hierarchical organization form. Enterprise network is the innovation of enterprise organizational form, which is beneficial for enterprises to obtain external resources, form rapidly, and maintain a lasting competitive advantage. But because each enterprise in enterprise network is an independent corporate entity, they occupy a certain resources and have a certain decision making authority, it is necessary to establish effective coordination mechanism to improve the performance of enterprise network. The influencing factors on the enterprise network coordination mainly include the structure of the enterprise network, information exchange among enterprise network behavior, trust degree, coordination cost, cultural compatibility and enterprise network environment.

Abstract: Coordination effect among enterprise network behavior subjects could be evaluated by coordination maturity. Maturity model of enterprise network resource coordination includes four dimensions: the coordination cost, coordination process, coordination method as well as the ability to learn. According to the level of the four dimensions, they can be divided into four levels: the initial level, aggregate level, standard level and optimization level. The scientific evaluation of enterprise network resource coordination maturity, can let the enterprise network behavior subjects understand the condition of resources coordination in their network, thereby improve the degree of network resource coordination, improve and perfect coordination mechanism. Therefore, this text has established the enterprise network resource coordinate maturity index system, which includes six first level indexes and second level indexes. The first level indexes include coordination costs, exchange of information, intelligence resource sharing degree, corporate culture synergy degree, smooth communication and problem solving ability for coordination subjects to the feedback.

Abstract: Based on the detonation shock dynamics (DSD) theory, Level Set method for propagation of detonation wave was researched. In order to compute the propagation of small curvature bending detonation wave accurately, and according to characteristic of the Hamilton-Jacobi equation, the unstructured quadrilateral and Galerkin finite element difference scheme for solving Level Set function equation was studied.The finite-element code LS-DYNA was used to compute the experimental models about the propagation of detonation wave and the motion of flyers driven by explosive. The computation results are in good agreement with the experimental data. The results indicate that the difference scheme is of high accuracy and universal application.

Abstract: In the past twenty years, traditional manufacturing industry has great influences on China’s economic growth but it meets more and more difficulties in the new economy. This paper aims to trace the successful organization design of firms in traditional manufacturing industry that have sustainable development in the new economy evolution. So this paper first reveals the relationship between organization design and new economy evolution for traditional manufacturing. Then put forwards an empirical analysis with firms in Lanxi cotton textile industrial cluster in Zhejiang province. The results show that the new economy evolution has a positive effect on organization design. In detail, in the five factors of new economy evolution, only the resources in new economy has a negative influence to organization design.

Abstract: Retrieval, recall rate and precision are not acceptable according to the general search engine in searching networked manufacturing resource. Manufacturing Resource Domain Ontology was derived and established based on the concept of the ontology in this paper. Model description was completed with protégé.

Abstract: The laboratory timetable problem is an NP combinatorial optimization problem, and it is difficult to get the optimal solution. Under the traditional timetable algorithm, classes are arranged by week, and it is fixed and regular that when and where classes are arranged. Whereas under special laboratory timetable algorithm, teachers need book in advance, classes are arranged by term, and it is very flexible and random. So the traditional timetable algorithm cannot solve the problem of the laboratory timetable. In order to solve this problem, a special laboratory timetable algorithm and a solving conflicting method are presented in this paper. It has been proven that it is a better solution to the laboratory timetable problem, saves a lot of time for the laboratory personnel and is worth further promote the application.

Abstract: Curriculum design is the key to teaching practice in analog electronics design, the curriculum design of analog electronics technology is a follow-up course who after completing the analog electronics. Through the steps of the design, welding, commissioning, and eventually completed the course requirements of the physical works. The design of analog electronic courses can let students understand the design process of an electronic works which for the tops of design, drawing, welding, assembling, testing, etc. Greatly improve the students’ practical ability. On the other hand, by the application of theoretical knowledge, students can also greatly improve the theory and solve practical problems. The ability to learn lots of knowledge can not be learned from textbooks. But at the same time, in curriculum design, will also facing unexpected contradictions, these contradictions show the contradiction between the analog electronics course design and quality control. Therefore, in order to solve the problems in the design of analog electronics courses, improve the quality of students who have completed their work. The curriculum design of analog electronics technology must have a strong quality control system compatible with the curriculum design.
