考虑预防性维护的多塔吊生产调度建模——以装配式建筑为例

Production Scheduling Modeling of Multi Tower Cranes Considering Preventive Maintenance—Taking Prefabricated Buildings as an Example

在装配式建筑施工过程中,塔吊作为重要设备之一决定施工现场效率,通过预防性维护保证塔吊的安全度来确保施工过程的顺利进行,本文以多台并行塔吊作为研究对象,采取可靠性判断的预防性维护的方式,以最小化完工时间作为优化目标,构件预防性维护调度模型,利用遗传算法对其进行求解,对比根据可靠性预防性维护和周期维护方式的总工时,得出可靠性预防性维护方式可以有效提高施工效率,减少工时,同时保证塔吊的低故障率。

During the construction of prefabricated buildings, tower cranes, as one of the important equipments, determine the efficiency of the construction site, and ensure the smooth progress of the construction process by ensuring the safety of tower cranes through preventive maintenance. This paper takes multiple parallel tower cranes as the research object, adopts the preventive maintenance method of reliability judgment, and takes minimizing the completion time as the optimization goal. Genetic algorithm is used to solve the problem. By comparing the total working hours of reliability preventive maintenance and periodic maintenance, it is concluded that reliability preventive maintenance can effectively improve construction efficiency, reduce working hours, and ensure low failure rate of tower cranes.
