For the development of high-functional and complex mechatronics products, it is becoming necessary to manage the design process considering multi-domains such as electrical, mechanical and software specialties. However, at present, in the process of embedded software development, the software developers often have to spend their time and efforts by wasteful and unnecessary design iterations because that they don't understand the original requirements and previous designing intentions exactly. The authors predict that the mechanical designers in previous processes, don't describe the reasons, how to analyze and why to adoption technologies insufficiently. In this paper, the authors propose that the requirement model should be introduced in development process, because all designers can understand "what to make" precisely. In reference of the studies of various requirement definitions, especially object-oriented approach, the authors studied that the procedure of description in the requirement model, which is suitable for the development of high-functional and complex mechatronics products. An intelligent crane system is designed as an example to examine the possibilities of description using SysML. In conclusion, proposed requirement model is confirmed that it can surely describe the product requirement of the mechatronics product.

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.
