Abstract:

Tactical simulation is an important part of combat simulation. It is a simulation of team tactical level. It includes the overall decision of the team and the individual behavior of the members. The decision-making behavior of the team usually focuses on the coorperation among the team members. However, the individual behavior of members is susceptible to various battlefield factors. If the behavior model is established only at one level, the behavior description will be vague and complicated. In order to distinguish between team behavior and individual behavior, and improve the individual behavioral execution ability, the hierarchical behavior model based on behavior tree and HTN is proposed. The execution of tactical commands is divided into team decision-making layer and entity execution layer. The decision-making layer is based on the behavior tree to model the decision-making behavior of the team, and the assessment method which considering path-finding distance factor and weapon threat factor is proposed to solve the key tactical position selection problem. The entity execution layer is based on HTN to model the behavior of the combat entity, and uses HTN planning algorithm to plan the individual mission plan according to the decision behavior result, it enhances the expression ability of the entity behavior description. The effectiveness of the hierarchical behavior model is verified by experiments.
