Method, device and storage medium for constructing requirement behavior tree

Abstract

Various embodiments of the teachings herein include methods for constructing a requirement behavior tree. An example includes: receiving a material bill including names of parts involved in a current assembly; obtaining a mechanical drawing of each part in the material bill; establishing multiple candidate pairings based on obtained mechanical drawings, wherein each of the multiple candidate pairings is composed of mechanical drawings of two parts; matching each of the multiple candidate pairings with each of pre-established regular pairings and regarding candidate pairings each of which matches a regular paring as target candidate pairings; for each target candidate pairing, adding assembly process information of a regular pairing matching the target candidate pairing to the target candidate pairing; and based on the assembly process information of all target candidate pairings, constructing a requirement behavior tree corresponding to a whole assembly process of the current assembly according to behavior tree syntax.
