Model-Based Systems Engineering with the SPES Modeling Language

This open access book presents the results of the project "SysML Workbench for the SPES Methodology" (SpesML), funded by the German Ministry of Education and Research. SpesML is a modeling language that supports the proven SPES methodology by a carefully selected subset of SysML language elements together with a precise semantic interpretation enabling advanced analyses.The book begins with an introduction to the SpesML project in Chapter 1 and the SPES modeling language (SpesML) in Chapter 2. Next, Chapter 3 discusses the introduction of Model-based Systems Engineering (MBSE) in industry and details the challenges faced by industrial practitioners. It also introduces a running example used throughout the book to demonstrate the application and tool implementation of SpesML. Chapter 4 introduces the SPES methodology. Starting with the fundamental principles applied in SPES, it briefly describes the underlying modeling theory and the Universal Interface Model (UIM) concept. Chapter 5 details the subset of language elements of SysML used in SpesML and introduces the concept of expressions as an extension of SysML for formal behavior descriptions. Chapter 6 continues with the realization of the core building blocks in SPES (UIM, viewpoints, granularity layers) through SpesML language elements. Chapter 7 then describes the implementation of a SpesML plugin on top of MagicDraw. Eventually, Chapter 8 introduces three industry case studies, and Chapter 9 concludes with a summary and an outlook. This open access book is written for both researchers in model-based systems engineering and for industry professionals exploiting model-based approaches for systems development. It adds to the development of the SPES methodology described in the three books "Model-Based Engineering of Embedded Systems", "Advanced Model-Based Engineering of Embedded Systems", and "Model-Based Engineering of Collaborative Embedded Systems".
