## 1 Introduction  
\"One Belt and One Road\" which originated in China, is the one of longest economic corridors and the most promising economic cooperation zones in the world. In October 2013, China first proposed the initiative of jointly building the 21 st century \"Marine Silk Road\" [1]. The Marine Silk Road will be of great and far-reaching significance, for it will enhance international cooperation, promoting common economic development, friendship, and cultural exchanges among the people from different cultural traditions, by building a marine shipping network composed of ports and routes and establishing communication channels among the countries along the route [2]. The Marine Silk Road refers to the marine section of the historic Silk Road that linked China, Southeast Asia, Indian subcontinent, Arabian Peninsula, Somalia, Egypt, and the European subcontinent. From 2001 to 2015, China's trade with the countries along the belt and road has grown from US $8.4 billion to US $112 billion, of which China's trade with 11 countries in the Southeast Asia has reached US $48.03 billion. The cooperation of the countries in regard to marine-cultural, marine engineering technology, and marine tourism will contribute to the countries' economic development [3]. However, the development of the Marine Silk Road will also bring about a certain potential challenges and risks to the countries involved [1], such as the risk of meteorological disaster [4], the risk of the international cultural conflict [5], and the economic and social risk led by national policies [6], etc. Therefore, in order to escort the sustainable development of the Marine Silk Road and promote economic and cultural development of the countries along the route, it is necessary to accurately identify, assess and effectively prevent the risks it may face. [PERSON] focused on the assessment and early warning of marine traffic safety risks under severe weather such as storms and high waves [7]. Most of the researches on risk assessment have been carried out on the social and economic disaster bodies in small regions [8]. Some scholars have conducted researches on emergency measures after disasters, such as grouping and ranking the rescue needs of different regions [9]. [PERSON] et al. focus on typical risks in different regions such as Southeast Asia, South Asia and Africa [10]. [PERSON] studied the cultural conflicts in the development of the \"Belt and Road\" [5]. However, most of the existing studies focus on the risk of the Marine Silk Road only in specific aspects. In addition, there is no in-depth analysis of the internal connection of various prevention methods, and there is also a lack of a systematically integrating framework to provide guidance toward the intelligent prevention of the risks involved in Marine Silk Road. Therefore, it is necessary to conduct researches aimed at providing a reliable risk prevention system to promote the development and smooth seotout of the Marine Silk Road. In this context, this study which intends to develop an intelligent risk-prevention system for the Marine Silk Road will contribute to both literature and practice. To do so, we follow three steps in our analysis. First, we establish a theoretical framework of systematic prevention system against various risks which the Marine Silk Road may face, sort out the risks systematically and identify the potential risks of the Marine Silk Road accurately. Second, a multilevel decision model which combines Fuzzy set theory, a decision test and evaluation laboratory (DEMATEL), and an explanatory structure model (ISM) is established to evaluate the performance and relationship of various prevention methods. Third, based on the results of the first two steps above, an operational and feasible intelligent risk prevention system is established and guidance is provided for the sustainable development of the Marine Silk Road. Based on the empirical results, we try to draw conclusions from the following four perspectives.
