DEVELOPMENT OF A MATHEMATICAL MODEL OF TOTAL COSTS FOR THE INTRODUCTION OF MEASURES TO PREVENT AND REMOVE EXPECTED LOSS FROM MARINE EVENTS

Abstract

According to the requirements of the International Code of Safety Management, each shipping company must develop, implement and maintain safety management systems. The purpose of the work is to improve the efficiency of the navigation safety management system. According to the purpose of the work, taking into account the peculiarities of managing the safety of navigation at sea, the presence of a contradiction in the subject area under study was revealed. On the one hand, it is necessary to determine the level of navigation safety improvement for each shipping company, which will be optimal from the point of view of the shipping company's economy and navigation safety. On the other hand, there are no effective formal methods and models for solving the problems of managing the risk factors of emergency marine events that ensure minimization of the costs of implementing measures to prevent and eliminate the expected damage from emergency marine events. The article develops a mathematical model of the total costs for the implementation of measures to prevent and eliminate the expected damage from emergency marine events in the navigation safety management system, taking into account the effectiveness of the relevant measures. The proposed mathematical model of total costs makes it possible to determine the target level of improving the navigation safety management system with the minimum total costs for the implementation of the necessary measures.
