The method for estimating and controlling the coastal navigation mark measurement and control cost of the coastal navigation mark measurement and control project is to maintain the safety of the coastal navigation mark measurement and control project, to reduce the cost of the project and to guarantee the service level. The traditional cost estimation method of the coastal navigation mark measurement and control project is based on the experience-based evaluation of the cost prediction model of the coastal navigation mark measurement and control engineering, which cannot effectively meet the principle of minimizing the present value of the measurement and control cost of the coastal navigation mark and the maximization of the state index during the service life period. In this paper, a method for estimating the cost of a coastal navigation mark measurement and control project based on the characteristics of large data correlation is proposed, and the measurement and control model of the conventional coastal navigation mark is designed. Cost estimation model of coastal navigation mark measurement and control project based on performance and energy supply survival period assessment model based on comprehensive coastal navigation mark measurement and control strategy. The cost estimation model of the coastal navigation mark measurement and control engineering is designed by using the first-order Bessel function, a reliable index evaluation equation of the cost all-sample regression analysis is obtained, the measurement and control cost of the coastal navigation mark, the user cost and the social cost are calculated. The cost present value of the measurement and control project of the coastal navigation mark is minimized as the objective function, and the financial constraint and the performance constraint are obtained as the boundary conditions. The plan optimization of the cost of the measurement and control engineering of the coastal navigation mark is realized, and the measurement and control scheme of the coastal navigation mark with the minimum cost present value is obtained under the limited financial resources. The numerical simulation results show that the model can improve the reliability and reliability of the measurement and control engineering structure of the coastal navigation mark, optimize the measurement and control cost of the coastal navigation mark, and obtain the minimum measurement and control scheme of the coastal navigation mark with the minimum cost present value under the limited financial resources, thus saving the measurement and control cost of the coastal navigation mark by 15%.
