Optimal Layout of Asphalt Mixing Plant Based on Dynamic Programming Algorithm

The optimal layout of asphalt mixing plant is the key problem of expressway construction. This paper studies the basic method of optimal layout of asphalt concrete mixing plant by establishing an integer programming mathematical model and combining the dynamic programming algorithm. the optimal layout of asphalt mixing stations and the supply relationship of asphalt concrete between each section and the asphalt mixing station are obtained through the establishment of integer programming mathematical model and dynamic programming calculation, and the total transportation time of transport vehicles is 8030 min. Combined with the analysis of the layout and transportation scheme of asphalt concrete mixing plant in 7 sections of Linyi Tengzhou expressway, the conclusion can be used as a reference for the application of similar projects.
