针对航空运输中旅客行李在自助托运系统中的检测和传输控制问题,提出了一种基于有限状态机和粗糙集相结合的流程控制方法。首先根据托运行李的各个阶段进行行李状态的划分,以检测传感器作为转换条件,传输动作作为转换动作,建立系统的有限状态机模型。而后将状态和转换条件作为条件属性,动作作为决策属性,生成系统控制决策表。最后,基于粗糙集方法将决策表分解并约简得到精简子决策表,从而简化了行李的检测和传输的控制复杂度。实验验证了该算法在自助行李托运系统中的实时性和有效性。
Aiming at the detection and transmission control of passenger baggage in self-check-in system in air transport, a flow control method based on finite state machine and rough set is proposed. Firstly, according to each stage of checked baggage, the state of baggage is divided to detect the sensor as the transition condition and the transmission action as the conversion action to establish the finite state machine model of the system. Then state and transition conditions are used as condition attributes and actions as decision attributes to generate system control decision table. Finally, the decision table is decomposed and reduced based on the rough set method to get the decision table of streamlined staff, thus simplifying the control complexity of baggage detection and transmission. The experiment verifies the real-time and effectiveness of the algorithm in self-service baggage handling system.
