Abstract: To effectively resolve manipulation conflicts generated by assembly program difference and formulate rational program in distributed collaborative assemble process, hierarchical conflict resolution based on intelligent comprehension was proposed. According to detail precision of assemble process description, conflicts were divided into assemble-operation conflicts, assemble-path conflicts and assemble-sequence conflicts based on the assemble behavior, and the key features of conflicts were defined. Conflict cell was created to store conflict in unified way. Difference of user　s operational intent was distinguished on the basis of manipulation ramification degree. According to constraints of assembling site, conflicts were intelligent resolved at the systemic level based on authority factor of assemble control, and the resolution process was visualized on this basis. The memebers in distributed collaborative assemble system could compare with each others, confer with others by interactive way and map out uniform assemble program intuitively by using different manipulation of conflict cell storage. The effectiveness of proposed method was verified by examples.
