To deal with this problem, a new method was developed by the combination of improved technique for order preference by similarity ideal solution method, analytical hierarchy process method and the network response surface method. The risk probability was calculated by adopting network response surface analysis based on the state variable of a known event and its degree of membership.This quantification method was applied to an offshore platform project, Bonan oil and gas field project in Bohai Bay in June 2004.There were 7 sub-projects and each includes 4 risk factors.The values of 28 risk factors, ranging from 10^-6 to 10^-4, were achieved. This precision conforms to the international principle of as low as reasonably practically.The evaluation indicates that the values of comprehensive level of construction group and ability of technical personnel on the spot are relatively high among all risk factors, so these two factors should be paid more attention to in offshore platform construction.展开更多

Autonomous learning platforms have become an important channel to help students learn. From the literature, there is a lot of research on English platform learning and use, but the research on students' autonomous construction and use of learning platform is relatively small, which is worth studying. This study tracked and investigated the self-built learning platform projects of two university students' innovation and entrepreneurship teams in Guangxi University of Foreign Languages. Using the methods of observation, questionnaire and interview, this paper analyzes the specific conditions of the English learning platform independently constructed by the two College Students Innovation and Entrepreneurship Program students, the difficulties and gains encountered in the construction of the platform, and the users' use of the platform. The study found that students encountered different difficulties in different periods of constructing learning platforms. With the resolution of the difficulties, they have gained a lot of new knowledge and skills. Some students have produced their own research topics in the process of building a learning platform. For platform users, most people like two platforms because they can broaden their knowledge. Some people do not have a strong desire to use it, partly because they do not plan their study well and partly because they think that platform learning is not efficient. The inspiration from the research: the construction of learning platform for students is a process of learning and experience;Students need more patience and more study and research if they want to build a learning platform.展开更多

Thus, the key to introducing this technology into construction industry is to improve AGV’s stability and autonomous navigation ability in more complex three-dimensional environments. In this paper, mobileman, a novel tracked autonomous guide vehicle, is introduced. Compared with other construction robots, mobileman maximizes its load capacity on the basis of assuring accessibility. Furthermore, its modular designs and self-balancing platform enable it to cope with more complex challenging scenarios, such as staircase with 35-degree sloped staircase, while another modular design featured automated loading and unloading functionality. The mobile base specifications were presented in section two, and modular designs and exploration of the navigation system on construction site were illustrated in the rest of sections.展开更多
