Abstract:

The quantitative description of the flight ground support process modeling and accurate estimation of the service time are the keys for enhancing the efficiency of airport flight support services. A quantitative description support service model (SSM) is proposed for analyzing the actual process of airport support service using colored time petri nets (CTPNs). The model divides the support service into three parts, task, state and resource. This paper uses the basic elements of the colored Petri nets to describe the support task, the logical relationship of the task, the service state and the relationship with the support task, and the model is given by the mentioned work. Based on the model, a support service time simulation algorithm based on the Monte Carlo method (MC-SST) is proposed. Finally, an application case of large hub airport flight support service data analyzes and validates the error of the MC-SST estimation time and the real time, which illustrates the applicability and effectiveness of the CTPN-SSM model.
