Abstract: In order to solve the problems such as many influencing factors, high complexity and heavy workload, a hull section job shop scheduling system based on dynamic rules is designed. The paper analyzed and sorted out the current situation and affected factors of the ship enterprise's work scheduling, and proposed the overall design idea and functional framework scheme. The association constraint relationship was established for the key elements that affect the operation scheduling, such as workshop, site, equipment, and team. We combined the key elements with actual production feedback data, and built dynamic rules. Under the pre-constraint conditions of dynamic rules, the scheduling algorithm based on the fusion of genetic algorithm and greedy algorithm was adopted and the intelligent generating hull section job shop scheduling was realized.
