Chapter 2 – CESAM Framework

2.1 Elements of Systemics
Before going further, we first need to introduce the notions of interface and of system environment. These elements of systemics will indeed be useful for presenting further the CESAM framework. We refer to Definition 0.1 and Definition 0.2 of Section...

2.2 The three Architectural Visions (1/2)
We are now in position to introduce the three systems architectural visions which will be our first key systems architecting tool for analyzing any system.. The heterogeneity of the environment of a system requires to address it by means of...

2.2 The three Architectural Visions (2/2)
The constructional vision provides white box models of the system where one describes all concrete hardware, software and “humanware”Remember that men can be part of systems with either strong organizational dimensions such for instance as information systems, or when a...

2.3 CESAM Systems Architecture Pyramid
As discussed in the previous section, any system can be analyzed from an operational, functional and constructional perspective. In order to achieve such analyzes in practice, one must simply remember that one shall just ask three simple questionsThese questions shall...

2.4 More Systems Architecture Dimensions (1/2)
Architectural visions are however not the only architectural dimensions of a system. We shall now introduce a number of new dimensions that can be used to refine each architectural vision. As already discussed in section 0.1, one must now recall...

2.4 More Systems Architecture Dimensions (2/2)
The dynamic of a static element of a system S refers to its temporal behavior or equivalently to an algorithmic description of such a temporal behavior. Dynamics are completely crucial if one wants to precisely specify the behavior of any...

2.5 CESAM Systems Architecture Matrix
We are now in position to introduce CESAM Systems Architecture Matrix, which is presented in Table 7 below. This matrix is just a synthesis of the different architectural dimensions that we introduced within this chapter. It indeed presents all the...
