Prefabrication‐based construction has several advantages, such as short building time and superior quality. The transportation of prefabricated products from factories to construction sites has two key issues to consider. One is how to efficiently utilize the capacity of trucks in order to use as few trucks as possible, and the other is how to postpone the transportation of prefabricated products so as to pay for them as late as possible. This study proposes a mathematical programming model to optimize the transportation planning of prefabricated products to minimize the sum of trucking transportation costs and inventory holding costs. Extensive numerical experiments show that the optimal transport plan generated by the model outperforms the plan obtained by a greedy approach by 10% of cost savings, implying the effectiveness of the model for the construction industry.

建筑中预制产品的最佳运输计划

基于预制的建筑具有多个优势，例如建造时间短和质量高。预制产品从工厂到建筑工地的运输要考虑两个关键问题。一种是如何有效利用卡车的容量，以便尽可能少地使用卡车，另一种是如何推迟预制产品的运输，以便尽早付款。这项研究提出了一个数学规划模型，以优化预制产品的运输计划，以最大程度地减少卡车运输成本和库存持有成本的总和。大量的数值实验表明，该模型生成的最佳运输计划比贪婪方法获得的计划节省了10％的成本，
