Abstract：A multi-level and multi-project optimization scheduling method for shipbuilding engineering based on chaotic grav-ity search intelligent algorithm is proposed in this paper.By combining constraint conditions and vector solving requirements to ob-tain a Pareto compromise solution set,and a shipbuilding engineering scheduling objective function is generated.By combining the results of multi-objective optimization processing with chaotic search initialization population,randomly inserting processing gene segments selected from the same craft,the approach can preserve the position genes of mutated individuals and finally obtain the op-timal solution.The method effectively avoides the decline in production schedule completion rate caused by conflicts between multi-ple objectives and multi-level and multi-project optimization scheduling in shipbuilding engineering is implemented.The experi-mental results show that the approach had obtained the highest completion rate of scheduling plans under different scheduling time periods,without any abnormal execution problems,and the high utilization efficiency is also acquired.
