Today, logistics activities have become a major source of pollution that affects the environment and green logistics is becoming a hot topic. A logistics company's operating strategy determines the direction of logistics activities and impact degree of logistics activities on the environment. And in logistics enterprises, there is a direct relationship between efficiency and collaboration as collaboration can reduce logistics costs and the negative impact of the bullwhip effect and increase the service level. Synergy degree evaluation, therefore, is crucial to analyze collaboration, identify vulnerabilities, promote development and is also a key step in building a green logistics system. This paper employs Synergetics to comprehensively evaluate the synergy degree in sustainable logistics enterprises. First, Synergetics is introduced to evaluate the synergy degree of sustainable logistics enterprises and the basic Synergetics principles are presented. Second, based on the Law of the Factors of Production, the synergy elements and logistics enterprise content is divided into three main factors: subject elements, object elements and facility and equipment elements. Then, a measurement model and framework for the synergy degree of logistics enterprises is built. Finally, a case study is given to verify the effectiveness of the proposed model and framework. It was found that the higher the logistics enterprise synergy degree, the higher the efficiency. influence on firm performance, which enabled the supply chain partners to achieve synergies and superior performance. Many organizations, such as Dell and Wal-Mart, have achieved mutual benefits from supply chain collaboration [13,14]. Multi-enterprise collaboration has also been examined. For example, Kefah [15] developed an integrated Game Theory (GT) approach for the coordination of multi-enterprise Supply Chains (SCs) in a competitive uncertain environment. Improving the collaboration between large and small-medium enterprises in the automobile production sector has been shown to be important for the profitability and sustainability of the collaborating companies [16]. However, there has not been a great deal of research into inter-departmental collaboration within an enterprise even though this could have a major influence on cost effectiveness and shipping time efficiency [17][18][19].In addition to this, synergy and complexity have a great impact on each other. The greater the degree of synergy among members, the more obvious synergy effects and the more complex coordination behaviors are produced [20]. An integrated supply model was proposed to formulate the problem of consignment-store-based complex supply chain optimization [21]. Tamás Bányai et al. demonstrated an enhanced harmony search algorithm to find the optimum make-or-buy solution of a given maintenance related supply chain complexity problem [22] and Danping Lin et al. have taken complexity as the technical factor when they adopt Internet of Things (IOT) in the agricultural supply chain [23].

In this paper, based on the problem of poor operation of sweet potato harvester, the discrete element method and TRIZ theory are used to optimize the key mechanism. Based on the discrete element method, EDEM software was used to simulate the operation process of the potato soil conveying and separating mechanism, and the optimal combination of working parameters was obtained. The linear velocity of the rod lift was 2.3 m/s, the inclination angle was 18 degrees, and the amplitude was 8 mm. Field experiments were carried out to verify the results. Through the problems in simulation and field experiment, based on TRIZ theory, the improvement scheme is proposed by using physical contradiction, and the two-stage potato soil transport separation mechanism is obtained. The simulation results show that the operation effect is improved obviously. Finally, the optimization of potato soil transport and separation mechanism is completed by determining the optimal working parameters and improving the structure innovation.
The processing of the huge amounts of information in the bioinformatics has been the bottleneck to restrict its development, and in this article, we used the distributed computation to solve this problem, and we described the structure, the design, the implementation of task decomposition, the distributed application program and the database management of the distributed computing platform. The distributed computing platform first decomposes one problem into many subtasks, and then the client sends the request of task computation for the server end, and the server end responses the request and takes out the information of the minimum subtask, and distribute the information to the client end. When the client end acquires the information of the subtask, it will transfer the operation module to compute, and when the task is completed, it will upload the result to the server end, and the server end repeats above process until all subtasks are completed, and according to the computation results of all subtasks, we can obtain the solution of the problem.
With the assistance of science and technology, micro-course has got wide attention and recognition as a new teaching method. This paper introduces the features of Moodle platform and functions of micro-course, analyses the designing procedure of micro teaching mode, and discusses the construction of micro-course module based on Moodle platform in details. Finally, this paper demonstrates the research and development of micro-course platform is both scientific and feasible based on the teaching practice of the AutoCAD of Landscape Design".
