Most of existed studies on the risk of multi-ship collision are based on the assessment of two-ship collision risk, and collision risk between the target ship and each interfering ship is calculated respectively, to determine the key avoidance ship. This method is far from the actual situation and has some defects. In open waters, it is of certain reference value when there are fewer ships, but in busy waters, it cannot well represent the risk degree of the target ship, since it lacks the assessment of the overall risk of the perceived area of the target ship. Based on analysis of complexity of ships group situation, the concept of relative domain was put forward and the model was constructed. On this basis, the relative collision risk was proposed, and the corresponding model was obtained, so as to realize risk assessment. Through the combination of real ship and simulation experiments, the variation trend, stability and sensitivity of the model were verified. The results showed that risk degree of the environment of ships in open and busy waters could be well assessed, and good references for decision-making process of ships collision avoidance could be provided.<\/jats:p>","DOI":"10.3233\/jifs-211025","type":"journal-article","created":{"date-parts":[[2021,10,29]],"date-time":"2021-10-29T11:41:46Z","timestamp":1635507706000},"page":"7137-7150","source":"Crossref","is-referenced-by-count":5,"title":["Modeling of relative collision risk based on the ships group situation"],"prefix":"10.1177","volume":"41","author":[{"given":"Xiaoyuan","family":"Wang","sequence":"first","affiliation":[{"name":"College of Electromechanical Engineering, Qingdao University of Science and Technology, Qingdao, China"},{"name":"Intelligent Shipping Technology Innovation and Comprehensive Experimental Base, Qingdao, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lulu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Intelligent Shipping Technology Innovation and Comprehensive Experimental Base, Qingdao, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gang","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Electromechanical Engineering, Qingdao University of Science and Technology, Qingdao, China"},{"name":"Intelligent Shipping Technology Innovation and Comprehensive Experimental Base, Qingdao, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Quanzheng","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Electromechanical Engineering, Qingdao University of Science and Technology, Qingdao, China"},{"name":"Intelligent Shipping Technology Innovation and Comprehensive Experimental Base, Qingdao, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guowen","family":"He","sequence":"additional","affiliation":[{"name":"College of Electromechanical Engineering, Qingdao University of Science and Technology, Qingdao, China"},{"name":"Intelligent Shipping Technology Innovation and Comprehensive Experimental Base, Qingdao, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/JIFS-211025_ref1","doi-asserted-by":"crossref","first-page":"1220","DOI":"10.1016\/j.eswa.2012.08.016","article-title":"An intelligent real-time multi-vessel collision risk assessment system from VTS view point based on fuzzy inference system","volume":"40","author":"Bukhari","year":"2013","journal-title":"Expert Syst.
