In the context of the transformation and upgrading of the traditional construction industry,the new construc-tion industrialization has promoted the development of assembled buildings.This study investigates the key aspects of logistics management in precast manufacturing enterprises.The multi-frequency vehicle scheduling problem is proposed to minimize the total transportation cost,considering the heterogeneous vehicle constraints,loader constraints,and time windows constraints.And then,a property-based hybrid genetic algorithm is designed to solve it.To solve the problem,a property-based three-dimensional encoding is designed to enlarge the search scope,a diversity assessment model based on demand partitioning and an adaptive adjustment mechanism are introduced to maintain population diversity and four different neighborhood strategies are proposed to further intensify the search in local regions.Finally,the effectiveness of the algorithm is verified by simulations experiments and algorithm comparisons on different instances.And the impact of vehicle purchase type and quantity on the transportation cost is also analyzed.
