Construction of a Civil Engineering Construction Machinery Scheduling Model Based on Queuing Theory

The civil engineering industry of China has rapidly developed over the recent years, and the high demand for civil engineering construction projects has increased the requirements for the operation of construction machineries. This paper attempts to construct a civil engineering construction machinery scheduling model based on queuing theory. First, the factors that influence the scheduling of civil engineering construction machinery were studied, and the internal factors of the system were analyzed using various tools and methods, including the genetic algorithm, the cross factor method, and the variation factor method. Second, using gantry and bridge cranes as examples, the civil engineering machinery scheduling model was analyzed through simulation and the relationship between queue length and machinery distribution was examined. The number of construction machineries and the distribution of the location on the project schedule both assist in the completion of multi-task civil engineering projects.
