Application of Non-player Character Simulation Technology in Union Dispatcher Training Simulator of Multi-level Dispatching and Control System

The joint anti-accident exercises between multilevel dispatching and control systems are using dispatcher training simulator (DTS). There are many problems with the existing DTS, such as communication difficulties, extraterritorial role simulation difficulties, uniformity of the training process, thus trainees cannot conduct self-training. This paper introduces non-player character (NPC) simulation technology into DTS to customize and intelligentize the training process. This paper firstly fused the NPC features of the game with the DTS system and established NPC model and behavior tree in DTS. Then simulation is conducted in behaviac software to realize the autonomous guidance and intelligent control of the simulation training process. The feasibility and effectiveness of NPC application in DTS are verified by comparison with the traditional DTS training process.
