Research on Reasonable Configuration of Electric Machinery in Highway Construction Scenes Based on Queuing Theory
The coordinated operation mode of electric dumpers and electric loaders has been pro-moted and applied in engineering construction or material handling projects.To reasonably configure the joint operation between electric machinery,based on the Muzhailing Tun-nel project of Weiyuan-Wudu Expressway in Gansu Province,the queuing theory is applied,and a mathematical model is established,to reasonably optimize the configuration between the electric loaders and dumpers,and the number of charging spots to be provided in the construction scenes is calculated.According to the calculation,the optimal configuration for this project is 1 electric loader paired with 5 electric dumpers,the production capacity of the electric loader under the optimal configura-tion is 412.23 m3 per shift,2 charging spots can satisfy the work intensity and charging needs of electric machinery,and the lowest earthwork cost per cubic meter is 1.64 yuan.The calcu-lated configuration results can bring obvious economic benefits for the project engineering.
