Research on the Modeling of Optimal Allocation of Engineering Machinery Groups for Road Emergency Maintenance

To solve the problem of allocation to various places of engineering machinery groups for road emergency maintenance, the characteristics of emergency maintenance were analyzed and the emergency maintenance process queue network and Petri net model were built to simulate the emergency maintenance process. Then the calculation method of maintenance time was put forward, and the mathematical model of optimal allocation of engineering machinery groups for road emergency maintenance is established, which provides the basis for solving the optimal allocation scheme of the engineering machinery groups.
