THE MAIN PRINCIPLES OF ASSESSING THE EFFICIENCY OF SHIP MAINTENANCE
Abstract
Introduction. The article considers modern problems of researching the efficiency of the cargo ship maintenance system. Comprehensive methods of guaranteeing the required efficiency of cargo ship maintenance systems consist of a set of measures to assess, improve, and control the reliability, accuracy, efficiency, quality of operation and other operational characteristics of cargo ships and available shipboard technical means. Integrated assurance methods are implemented both in the development and production of cargo ships and directly during their operation by the shipping company. The integrated use of methods for improving the efficiency of cargo ship maintenance systems opens ways to significantly improve the reliability and quality of operation of the cargo ship's functional systems. The basis of these methods is a quantitative assessment of the effectiveness of maintenance systems - a tool that allows to evaluate the effectiveness of the actions taken to ensure the required reliability and quality of maritime transport. The analysis of previous studies and publications indicates the absence of a single methodological approach to determining the performance indicators of cargo ship maintenance systems, which would allow considering the structure and frequency of maintenance, type of operational control, depth of recovery and external manifestation of failures. The purpose of the article is to consider the most typical of the published mathematical models of maintenance, to identify the common features of the models under consideration and to analyze the most typical mathematical models of maintenance to find a single methodological approach to determining the performance indicators of maintenance systems for maritime transport. Results. The most characteristic of the published mathematical models of maintenance with periodic monitoring of technical condition are considered. The features of the mathematical models of maintenance presented in this study are generalized. Conclusions. Thus, quantitative assessment of the levels of efficiency of maintenance systems is an important element in the scheme of calculating the efficiency of using cargo ships as commercial vehicles whose purpose of operation is to maximize profits at given high levels of safety and regularity of use. A detailed examination of the maintenance system reveals all the features of a complex ergatic system. At present, the theory of complex ergatic systems has a well-developed mathematical apparatus. Therefore, it is advisable to use the theory of complex ergatic systems to develop methodological foundations for analyzing and evaluating the efficiency of cargo ship maintenance systems and ship equipment.
