Study on Scheduling Problem of Agriculture Vehicles Based on Queuing Theory

In this paper, the mathematical model of two-nodes close queuing network is established by the Markov queuing network analysis method for harvesting machinery-vehicles-storehouse system. The study is carried out for the indicators which evaluate the quality of work (node output rate, average queue length, vehicle waiting number, average vehicle stay time, vehicle run time, interval distance between vehicles, machinery utilization rate) and the optimization of agricultural vehicle system. An example of application is realized. For a large matching of agricultural vehicles system, it is feasible to determine the optimal program for agricultural vehicles matching by adjusting different parameters of system, and calculating the utilization of machinery of system and the operating parameters of system.
