The amount of concrete needed in the construction of projects is enormous. The concrete dispatching in construction is, however, chaotic and causes grievous waste due to the tight construction schedule, heavy tasks, and improper transport vehicle dispatching by the constructor. This paper proposes a more realistic objective function in the vehicle dispatching algorithm and offers a solution to the rational dispatching of concrete transport vehicles. The analysis of the calculation example validates the feasibility of the built model, which provides more appropriate dispatching and more balanced distribution, meets the needs of the worksite and mixing station to the greatest extent and improves the level of project refinement and process management. Therefore, the model is worth promoting in future practice.
工程建设中所需混凝土的量十分巨大。然而，由于施工进度紧张、任务繁重以及施工方运输车辆调度不当，施工中的混凝土调度混乱，造成了严重浪费。本文在车辆调度算法中提出了一个更符合实际的目标函数，并给出了混凝土运输车辆合理调度的解决方案。计算实例分析验证了所建模型的可行性，该模型提供了更合适的调度和更均衡的分配，最大程度满足了施工现场和搅拌站的需求，提高了项目精细化和过程管理水平。因此，该模型在未来实践中值得推广。
