This paper proposes a method of impact analysis of the design change from the initial design stage. In author's previous work, a hierarchical requirement model is proposed in order to define the requirement of the complex mechatronics product. The product requirement is decomposed into three aspects: mechanical, electrical, and software. A hierarchical functional structure is proposed to represent the functional component in each design layer. The states and actions is designed as an activity diagram, and decomposed into the activity diagram in the next design stage. A constraint diagram is proposed to assign behavior elements and technical specifications. A decomposition process of the states, actions, and values is visualized using dependency structure matrix. The design change propagation analysis is proposed based on matrix between components, object flows, states, actions, and values. The proposed method is developed as a proto-type system based on SysML specifications and using Rhapsody. An intelligent crane system is designed as an example. A design change of the required behavior and actions is tested. The design result indicated that the proposed method surely can provide an affected components, parameters, and technical specifications with the change of requirement behavior.
