Preface
Systems engineering is a multidisciplinary and holistic approach to develop solutions for complex engineering problems. The continuing increase in system complexity demands more rigorous and formalized systems engineering practices. In response to this demand—along with advancements in computer technology—the practice of systems engineering is undergoing a fundamental transition from a document-based approach to a model-based approach. In a model-based approach, the emphasis shifts from producing and controlling documentation about the system to producing and controlling a coherent model of the system. Model-based systems engineering (MBSE) can help to manage complexity, while improving design quality and cycle time, enhancinging communication among a diverse development team, and facilitating knowledge capture and design evolution. A standardized and robust modeling language is considered a critical enabler for MBSE. The Systems Modeling Language (OMG SysML™) is one such general-purpose modeling language that supports the specification, design, analysis, and verification of systems that may include hardware and equipment, software, data, personnel, procedures, and facilities. SysML is a graphical modeling language with a semantic foundation for representing requirements, behavior, structure, and properties of the system and its components. It is intended to model systems from a broad range of industry domains such as aerospace, automotive, health care, and others. SysML is an extension of the Unified Modeling Language (UML), version 2, which is the de facto standard software modeling language. Requirements were issued by the Object Management Group (OMG) in March 2003 to extend UML to support systems modeling. UML was selected as the basis for SysML because it is a robust language that addresses many of the systems modeling needs, while enabling the systems engineering community to leverage the broad base of experience and tool vendors that support UML. This approach also facilitates the integration of systems and software modeling, which has become increasingly important for today’s software-intensive systems. The development of the language specification was a collaborative effort between members of the OMG, the International Council on Systems Engineering (INCOSE), and the AP233 Working Group of the International Standards Organization (ISO). Following three years of development, the OMG SysML specification was adopted by the OMG in May 2006, and the formal version 1.0 language specification was released in September 2007. Since that time, new versions of the language have been adopted by the OMG. This edition is intended to reflect the SysML 1.4 specification. It is expected that SysML will continue to evolve in its expressiveness, precision, usability, and interoperability through further revisions to the specification based on feedback from end users, tool vendors, and research activities. Information on the latest version of SysML, tool implementations of SysML, and related resources, are available on the official OMG SysML web site at http://www.omgsysml.org/. Book Organization
This book provides the foundation for understanding and applying SysML to model systems as part of a model-based systems engineering approach. The book is organized into four parts: Introduction, Language Description, Examples of Model-Based Systems Engineering Methods, and Transitioning to Model-Based Systems Engineering. Part I, Introduction, contains four chapters that provide an overview of systems engineering, a summary of key MBSE concepts, a chapter on getting started with SysML, and a sample problem to highlight the basic features of SysML. The systems engineering overview and MBSE concepts in Chapters 1 and 2 set the context for SysML, and Chapters 3 and 4 provide an introduction to SysML. Part II, Language Description, provides the detailed description of the language. Chapter 5 provides an overview of SysML diagrams and some common diagrammatic notations. Chapters 6 through 14 describe key concepts related to model organization, blocks, parametrics, activities, interactions, states, use cases, requirements, and allocations. Chapter 15 describes the SysML specification and language architecture, and extension mechanisms to customize the language. The ordering of the chapters and the concepts are not based on the ordering of activities in the systems engineering process but are based on the dependencies between the language concepts. Each chapter builds the reader’s understanding of the language concepts by introducing SysML constructs: their meaning, notation, and examples of how they are used. The example used to demonstrate the language throughout Part II is a security surveillance system. This example should be understandable to most readers and has sufficient complexity to demonstrate the language concepts. Part III, Examples of Model-Based Systems Engineering Methods, includes two examples to illustrate how SysML can support different MBSE methods. The first example in Chapter 16 is a functional analysis and allocation method to specify and design a water distiller system. The second example in Chapter 17 applies to the design of a security system consisting of a central monitoring station and multiple sites that are monitored. It uses a comprehensive object-oriented systems engineering method (OOSEM) and emphasizes how the language is used to address a range of systems engineering concerns, including black-box versus white-box design, logical versus physical design, and the design of distributed systems. While these two methods are considered representative of how MBSE with SysML can be applied to model systems, SysML is intended to support other MBSE methods as well. Part IV, Transitioning to Model-Based Systems Engineering, addresses key considerations for transitioning to an MBSE approach with SysML. Chapter 18 describes how to integrate SysML into a systems development environment consisting of multi-disciplinary engineering tools. It describes the different types of models and tools, the type of data that is exchanged, and mechanisms and standards for data exchange. It also includes a discussion on the selection criteria for a SysML modeling tool. Chapter 19 is the last chapter of the book and describes processes and strategies for deploying MBSE with SysML in an organization. Emphasis is placed on leveraging the organization’s improvement process to assess, plan, and pilot the MBSE capability prior to deploying the capability to projects, and on other essential elements for a successful implementation of MBSE. Questions are included at the end of each chapter to test readers’ understanding of the material. The answers to the questions can be found on the web site for this book at http://www.elsevierdirect.com/companions/9780123852069/. The Appendix contains the SysML notation tables. These tables provide a reference guide for SysML notation along with a cross reference to the applicable sections in Part II of the book where the language constructs are described in detail. Uses of this Book
This book is a practical guide targeted at a broad spectrum of industry practitioners and students. It can serve as an introduction and reference for practitioners, as well as a text for courses in systems modeling and model-based systems engineering. In addition, because SysML reuses many UML concepts, software engineers familiar with UML can use this information as a basis for understanding systems engineering concepts. Also, many systems engineering concepts come to light when using an expressive language, which enables this book to be used to help teach systems engineering concepts. Finally, this book can serve as a primary reference to prepare for the OMG Certified System Modeling Professional (OCSMP) exam (refer to http://www.omg.org/ocsmp/). How to Read This Book
A first-time reader should pay close attention to the introductory chapters, including Getting Started with SysML in Chapter 3 and the application of the basic feature set of SysML to the Automobile Example in Chapter 4. The introductory reader may also choose to do a cursory reading of the overview sections in Part II, and then review the simplified distiller example in Part III. A more advanced reader may choose to read the introductory chapters, do a more comprehensive review of Part II, and then review the residential security example in Part III. Part IV is of general interest to those may be involved in deploying MBSE with SysML in their organization or project. The following recommendations apply when using this book as a primary reference for a course in SysML and MBSE. An instructor may refer to the course on SysML that was prepared and delivered by the Johns Hopkins University Applied Physics Lab that is available for download at http://www.jhuapl.edu/ott/Technologies//Copyright/SysML.asp. This course provides an introduction to the basic features of SysML so that students can begin to apply the language to their projects. This course consists of eleven modules that use this book as the basis for the course material. The course material for the language concepts is included in the download, but the course material for the tool instruction is not included. A shorter version of this course is also included on the Johns Hopkins site, which has been used as a full-day tutorial to provide an introductory short course on SysML. A second course on the same website summarizes the Object-Oriented Systems Engineering...
