Key factors analysis of maritime patrol in maritime safety management based on fuzzy analytic hierarchy process

Abstract

Maritime patrol is a vital part in maritime safety management. In order to improve the maritime patrol quality and have a better implementation of IMO convention, the fuzzy analytic hierarchy process (F-AHP) is used to analyse and identify the key factors of maritime patrol, and provide technical support for the subsequent fuzzy comprehensive evaluation of maritime patrol. Comprehensive expert survey finds key factors of maritime patrol, and builds an analytic hierarchy model. The index system is divided into several subsystems and sub-modules for research, and then qualitative evaluation is converted into quantitative data and the synthetic weight of each element is obtained through judgment matrix and weight calculation. The results show that the five key factors, completion of planned patrol mileage, time consumed for restoration of navigation order, number of complaints about maritime patrol, normal usage of AIS on ships in the area, main area patrol frequency are identified as key safety elements in maritime patrol.
