Architecture Definition and Design Definition

This chapter provides readers with the opportunity to learn principles and practices of architecture definition and design definition and the techniques used to control the complexity of system architecture and design. It covers architecture definition, design definition, and the Realistic Corporation driving system simulator (RC‐DSS) case study. The System Modeling Language (SysML) provides notations that can be used to define system requirements, system architectures, and system designs. The three SysML diagrams for defining system structure are: package diagrams; block definition diagrams; and Internal block diagrams. The four SysML diagrams for defining system behavior are illustrated for the driving system simulator case study. They are: sequence diagrams, activity diagrams, state machine diagrams, and use case diagrams. The chapter illustrates various kinds of SysML diagrams that can be used to define the RC‐DSS architecture (structure and behavior). It also presents design considerations for the vehicle cabin and other elements of the architecture.
