Model-based Systems Architecting

Appendix 3Example of System Model Managed with CESAM

We shall now dedicate this appendix to the presentation of a quite complete system model managed with the CESAM framework. After introducing the system of interest that we shall use to this aim, we shall present the main – environment, operational, functional and constructional – system views, as proposed by the CESAM approach, on the case study analyzed in this appendix.

A3.1. The system of interest

Figure A3.1. Our system of interest: a smartphone system. For a color version of this figure, see www.iste.co.uk/krob/systems.zip

In this appendix, the system of interest that we will study through a system analysis is a smartphone. It is a technological system that we easily use all day long and thus seems quite simple, but it is in fact a very complex system, which makes it particularly interesting to study (see Figure A3.1)!

At this point, we shall, however, just stress, for the reader who is not aware of this, that a smart phone is not at all a phone, in its traditional technological meaning, but a computer which was miniaturized and that emulates the main functionality of a phone.

A3.2. Environment architecture

The environment architecture of a smartphone system consists of a stakeholder hierarchy diagram where all stakeholders of the smartphone are hierarchically organized and an environment diagram which elicits the ...
