ABSTRACT
In order to recognize the process complexity better, the assembly system and its operation process are analyzed from different views, and the classification of an integrated process complexity is proposed in this paper. The paper is organized as follows. In section 1, we have given a brief introduction to the process complexity. In section 2, the process complexity in assembly system is first defined, and different dimensions to realize the process complexity is proposed. In section 3, 4 and 5, the process complexity is discussed from operation dimension, hierarchy dimension and time dimension respectively. In section 6, the integrate model is proposed. In section 7, we draw the conclusions and point out future works.
