The invention discloses a bus real-time scheduling method. The method comprises the following steps of defining an entity state and giving an initial state, defining a task network structure and giving an initial task network, defining domain knowledge, obtaining a current task network and a state set, decomposing the composite task into executable atomic tasks through the domain knowledge and state set, and selecting a corresponding operation execution task, updating an entity state and a task network, and continuously repeating until all tasks are executed. The invention provides a bus real-time scheduling method based on a hierarchical task network. A bus operation scheme can be given in real time through decomposition of composite tasks. According to the method, various emergencies inreal time can be effectively processed, a vehicle scheduling scheme is provided, the punctuality rate of the bus is improved, and the service quality of the bus is further improved.
Description
technical field [0001] The invention relates to the technical field of public transport real-time dispatching, in particular to a real-time public transport dispatching method. Background technique [0002] Due to the fluctuation of passenger flow at the bus station and the uncertainty of the operating environment, such as road congestion, bad weather, vehicle failure, etc., the bus operation service is often delayed and cannot be executed as planned, thus affecting the quality of bus service. Reasonable real-time adjustment of departure time can reduce the negative effects of these uncertain disturbances. For this reason, many studies are devoted to dynamic scheduling using control strategies. It can be mainly divided into offline scheduling and real-time scheduling. Offline scheduling is mainly to compensate for late arrival by designing a slack time for each one-way. However, due to the randomness of interference, even if a large slack time is set in advance, there is ...
