Abstract

In the context of maintenance of shipboard machinery of cargo ships, effective management of the maintenance process and optimization of resource intensity are an integral part of the successful operation of the shipping industry. However, today's existing methods of ship's equipment maintenance are mainly based on linear models that do not always consider the complex nature of technical condition changes. In this regard, the priority task is to develop and use more accurate models that would consider the nonlinearity of the process of changing the technical condition of ship's equipment. Such models will allow to predict changes in technical condition more accurately, determine the optimal time and scope of maintenance, and ensure efficient resource management. This article is devoted to the study of methods for modeling nonlinear processes of changes in the technical condition of shipboard technical equipment of cargo ships. The article determines that the tasks of optimizing the maintenance of cargo ships can be better solved by using nonlinear mathematical models of changes in the technical condition of ship's technical equipment. A comparative analysis of linear and nonlinear models is carried out, considering their impact on the duration of the maintenance cycle, residual life and costs of spare parts. The influence of variation in the rate of change of the technical condition on the efficiency of maintenance is investigated. The relevance of this study is to improve the efficiency of cargo ship maintenance and optimize resource management.
