Abstract: To solve the problems such as low management efficiency of medium-term schedule planning of marine engineering production subsection construction and the result of planning decision not meeting the expected requirements of production,the constraint relation of schedule activities of subsection construction in actual shipbuilding enterprises was sorted out,and the method of time/work constraint under non-linear construction mode and its transformation into normal constraint were proposed.Based on the improvement of the multi-objective non-dominant genetic algorithm,the medium-term schedule planning optimization algorithm of marine engineering production subsection construction was designed,which took the construction period,cost increase and resource balance of a single ship project as the optimization objectives.Compared with other algorithms,the effectiveness and reliability of optimizing the medium-term schedule in the face of the problem of complex schedule network and non-linear construction mode were proved.
