Abstract: It is valuable to be researched in the application of science of complexity to the forest ecosystem. Forest ecosystem is an adaptive complex system which is suggested to be at the edge of chaos or at the criticality. The inner interaction of a forest ecosystem is the main driving force for the self-organization, complexity and order in the forest ecosystem. Forest ecosystem complexity is one of the research frontiers of ecological and evolutionary problems presently. The application of science of complexity to the forest ecosystem complexity studies, its concept, background, methodology and theory are briefly introduced. The forest ecosystem complexity is defined as the structure and function diversity, self-organization and the order of an ecosystem. Its main methods include the cellular automaton, genetic algorithm, game theory, complex network, etc. This paper has discussed mechanism and development of forest ecosystem complexity, by applying the principle and methods of science of complexity, which is a new approach for understanding ecological and evolutionary problems.

Abstract: When decision makers locate logistics distribution centers they will compete with the existing ones and with each other at the same time. The nonlinear bi-level program is modeled for two decision makers under network location environment. The upper and lower objective function is to maximize respective net profit which is the difference of profit and investment cost. Genetic algorithm is applied to solve the problem. A numerical example is also given to show the application. And the result shows that the decision maker who first locates is more dominant than the decision maker who locates later in the competition.

Abstract: The selection of Third-party reverse logistics supplier is key factor for the success implement of reverse logistics. In this paper an evaluation index system on the third-party logistics supplier is put forwarded according to the characteristics of reverse logistics, evaluation model is established by using the analytic hierarchy process and fuzzy synthetical method and an example of calculation is given. The result shows that the method is simple, accurate and has good application.

Abstract: Abstract: End-of-life electronic products have become a major environmental issue among countries. This is due to the growing number of end-of-life electronic products and their hazardous contents. The improper handling of their components not only causes the waste of resources, but also brings serious environmental pollution. Therefore, a reasonable construction of reverse logistics system for end-of-life electronic products is an urgent problem at present. This article introduces the importance of reverse logistics for end-of-life electronic products, and builds complete information dynamic game model about the government, manufacturers, third party reverse logistics provider and consumers. It discuss game equilibrium in the context of complete information in accordance with a certain sequence of actions, and finally obtains the decision of all participating subjects in the reverse logistics system for end-of-life electronic products. Keywords: reverse logistics; end-of-life electronic products; dynamic game

Abstract: Asphalt concrete is one material of pavement engineering. Owning to the density of AC factories in Taiwan is highly concentrated and with the characteristic of industrial structure and operations, the margin is not much. Under this situation, only the entrepreneur with efficiently manage could run the business. Recently, the production of AC is tended to be institutionalized, computerized and automated. But the produce schedule and distribution still need to arrange by experienced staff. To AC factory and the manager of construction site, it is a very important issue that how to efficiently produce and distribution with more benefit. This research is based on the traditional model of experienced vehicle deployment which recording the delivered paths, time and related information. By the systemize analysis, we could compare the difference output of intelligent vehicle deployment system between the traditional one. This way, the actual benefit of deployment system could be estimated. This research result could be help for decision making.

Abstract: In the Internet of Things, search service is that information which is corresponding to entities in real world is retrieve so as to help people achieve information that they need. From the angle of visualization, this paper study the search service in the Internet of Things. With the Vector-Space Model, entities' information is expressed as entity vectors, and a Voronoi diagram based Vector-Space Model visualization method is presented. According to similarity between entity vectors, entity vectors' position in two-dimensional plane is calculated and this plane is divided into Voronoi diagram by nodes as which feature vectors of entity vectors’ clustering are taken. According to similarity between query vector and feature vector, a Voronoi diagram based Vector-Space Model retrieval method is put forward. This method restricts the searching scope in Voronoi domain of feature vectors that are the most similar to query vector, thereby the number of compared entity vectors is reduced in the retrieval process. The experiment result indicates that this method can ensure retrieval precision and improve retrieval efficiency.

Abstract: With the rapid development of the manufacturing industry in China, the training of ERP talents becomes a hot issue in the fields of industry and education. An ERP simulation operation system is developed from the view of person training. The simplified ERP model is realized in the simulation system. In the design of the simulation system, the SSH2 frame structure is used and the whole system is built in a modular mode. The function module of simulation system is analyzed and the system technology implementation is described in detail. The trainees can understand knowledge and skills of ERP more easily by the proposed simulation system, which means that the presented system has the positive effect on the training of ERP talents.

Abstract: Considering the concept of service chain and the environment changes of supply chain logistics industry, the supply chain logistics based on service chain was proposed,on this basis of character, analysed the building of its service architecture and service information platform were deeply researched.

Abstract: According to the status of the china tobacco sorting system and equipment, this article provides an overall development trending of technology in sorting system and equipment based on the internet of things. Based on the research of key technologies in the high-speed automated sorting system and also the research of architecture mode, it can provide a reference for the overall system’s structure, capability, overall planning and the like through the network topology.

Abstract: ZnO-TiO₂ composite nanofibers were prepared by using the electrospun fibers of PVP/ZnSO₄/ Ti(OiPr)₄ composite as precursor, and through calcination treatment. The chemical components, structures and morphology were characterized by FT-IR, XRD, SEM, respectively. The photocatalytic activities of the catalysts were investigated by photocatalystic degradation of Rhodamine B under visible-light irradiation. It was found that the ZnO-TiO₂ composite nanofibers photocatalyst calcined at 600 °C which was mixed the anatase phase and rutile phase, showed higher photocatalytic activities than those calcined at other two temperatures. This result was expected as a new morphology of photocatalysts to degrade the organic pollutants in the sun.
