Environmental Crisis has been a global issue and how to build greening organizations and how to improve greening organizational performance have become focuses during organizational development. The study reveals the ecological values of open innovation and empirically validates the relationship between resource sharing under open innovation and greening organizational performance.
In the vehicle routing problem (VRP), it is usually difficult to confederate the cargo and arrange vehicles path. Due to performance reasons, the traditional shortest path algorithm can not be applied to the large scale of VRP. On the basis of the VRP mathematical model, this paper constructs a mixed climbing particle swarm algorithms to solve the problem. First, through coding, the VRP problem is...
In the visible light communication (VLC) system, the discrete multitone modulation (DMT) is one of the alternative efficient modulation schemes and the bit-power distribution among related carriers is crucial to the final channel capacity. In the paper, the channel capacity in Krongold algorithm is compared with the upper bound and the lower bound. The former is in the water-filling principle and...
Wireless communication network has such features as limited bandwidth, changeful channel and dynamic topology, etc. Ad hoc network has lots of difficulties in accessing control, bandwidth distribution, resource assign and congestion control. Therefore, a wireless resource distributing algorithm based on communication transmission performance factors is proposed in the paper. The algorithm makes quantitative...
The development of information-based education has greatly influenced the PE education ideal, conception, model, content and method, and it has also greatly changed college PE education, meanwhile pushed the reform of college education to a new high. The essay will analyze the necessity of development and construction of college PE education resource, and put forward measures to institutionalize the...
With the rapid development of network bandwidth, video resource use is everywhere, especially in teaching. Video question answering system in campus network realizes the framework and main functions based on the flash platform technology and provides a good platform for the students' autonomous learning. This paper mainly discusses the realization of the video function, in the question answering system,...
Unified Modeling Language is a visual modeling language based on object-oriented methods. It combines with vehicle management information system of logistics company for system analysis, date analysis and database design, system design. Business process diagram, use case diagram, class diagram and sequence diagram can be drawed by UML at the analysis stage. The theme database, logical and physical...
The (d, 1)-total labeling number of a graph delta dTG is the width of the smallest range of integers that suffices to label the vertices and the edges of G such that no two adjacent vertices have the same label, no two adjacent edges have the same label and the difference between the labels of a vertex and its incident edges is at least d. In this paper, we studied the upper bound of delta dTG of...
The efficiency and total factor productivity for 22 development zones in Shanghai were researched by data envelopment analysis method. Based on this, the efficiency of resource allocation for Shanghai Development Zones was analyzed. It was thought that: the production efficiency of the Development Zones in Shanghai comes mainly from scale efficiency. There is the problem of focusing on scale, paying...
Cooperation and development are the mainstream of current world, economic globalization and regional integration are the objective tendency that current world develops. Modern tourism development is inseparable from the regional cooperation, therefore, strengthening regional tourism cooperation is the objective requirement of the tourism industry's development, and is also the new impetus of regional...
Organizational sense of justice and organizational politics perception are key contents that organizational behavior focuses on. In combing research literature about organizational sense of justice and politics perception, we believe that both have significant correlation in concept, meaning, structure dimensions, which produce impact on employees' cognition and behavior from different levels. The...
