SysML for Systems Engineering: A Model-Based Approach — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

This chapter discusses the main systems engineering concepts that were introduced briefly in Chapter 1. Understanding the concepts is essential for a number of different reasons, some of which are obvious and some of which are more subtle: Clearly, by not understanding the basic concepts, actually performing any work in the world of systems engineering is going to be very difficult, to the point of impossibility. The only way to succeed while not understanding the concepts is through pure chance. This is not a good approach! In order to address the 'three evils' of systems engineering, understanding is crucial. It is one of the basic evils, as was discussed previously, that drives other two evils. The basic approach that is advocated in this book for model-based systems engineering (MBSE) is that of 'Ontology, Framework and Views'. The concepts needed for MBSE are defined in the so-called MBSE Ontology, which forms the cornerstone of any MBSE exercise. Understanding the concepts is, therefore, essential, and these concepts will defined using the MBSE Ontology. This Ontology will then be used throughout rest of this book for all of the examples, approaches and applications of MBSE.
