Operational Task Decomposition Method based on Extended HTN Planning

Abstract

As an important premise of operational task planning, the decomposition of operational tasks is of great significance to improve the combat effect and ensure the quality of mission completion. In view of the characteristics of strong randomness and complexity, the characteristics of operational task correlation are analyzed systematically, and the operational task constraint structure is defined, which is composed of task time constraint, logic constraint and function constraint. The measurement method of operational task correlation and task granularity is given. In this paper, domain knowledge is effectively introduced into the process of task decomposition, the method of operational task decomposition based on extended hierarchical task network (HTN) is proposed, and the specific process of task decomposition is given. The method is verified by an example. The results show that the method based on extended HTN is practical and can solve the problem of decomposition optimization of complex combat tasks effectively. The proposed decomposition scheme and improvement suggestions are operable and have certain practical application value.
