Up until a few years ago there were many different modelling languages available to software developers. However, this vast array of choice only served to hinder communication and as a result the Unified Modelling Language (UML) was born. Although the UML has its roots firmly in the software world, the benefits of adopting a standard visual notation have been recognised in many other fields, not least of which is the field of systems engineering. This book concentrates on systems-based applications, rather than the traditional software applications that are more usually associated with the UML. Now fully updated to reflect the changes to UML for its version 2.0 release, this new edition has been substantially re-written and includes new material on systems architectures and life cycle management.

The practice of Model-based Systems Engineering is becoming more widely adopted in industry, academia and commerce and, as the use of modelling matures in the real world, so the need for more guidance on how to model effectively and efficiently becomes more prominent. This book describes a number of systems-level 'patterns' (pre-defined, reusable sets of views) that may be applied using the systems modelling language SysML for the development of any number of different applications and as the foundations for a system model.Topics covered include: what is a pattern? Interface definition pattern; traceability pattern; test pattern; epoch pattern; life cycle pattern; evidence pattern; description pattern; context pattern; analysis pattern; model maturity pattern; requirements modelling; expanded requirements modelling; process modelling; competence modelling; life cycle modelling; defining patterns; and using patterns for model assessment, model definition and for model retro-fitting.This book forms a companion volume to both SysML for Systems Engineering - a model-based approach and Model-based Requirements Engineering, both published by the IET. Whereas the previous volumes presented the case for modelling and provided an in-depth overview of SysML, this book focusses on a set of 'patterns' as the basis of an MBSE model and their use in today's systems engineering community.

Systems Modelling Language (SysML) is a tailored version of the unified modelling language (UML) that meets the needs of today's systems engineering professionals and engineers. It supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems, including hardware, software, information, personnel, procedures, and facilities in a graphical notation.SysML for Systems Engineering: A model-based approach provides a comprehensive overview on how to implement SysML and Model-based Systems Engineering (MBSE) in an organisation in order to model real projects effectively and efficiently. Topics covered include approach and concepts; SysML notation; diagramming guidelines; process and requirements modelling with MBSE; architectures and architectural frameworks with MBSE; value chain modelling; deploying MBSE; the benefits of MBSE; the 'people', the 'process' and the 'tool'; model structure and management; and model maturity. A detailed case study is included to illustrate the key concepts.Fully updated and revised to reflect the latest version of the standard (SysML 1.5, released in May 2017), this new edition also includes new chapters on the benefits of MBSE, model management, model maturity and value chain modelling.

Written by an internationally-recognized systems engineering expert, this updated edition provides insight into elements to consider when designing a complex system that is robust and successful.The latest edition covers the new approaches of Model-Based Systems Engineering (MBSE) and its deployment techniques using the Trinity approach. You will learn about the system engineering life cycle and processes to implement. Effective systems can be built only when the system is designed with close attention to detail, meaning each aspect of the system is recognized and understood before the system is built. The book explains in great detail, different system models and visualization techniques, with a focus on SysML, to help you visualize a system in the design phase. You will also learn various verification and validation techniques to ensure your system design is ready to be implemented. The book ends with key management processes, systems engineering best practices, and guidelines, with a new section on effective approaches based on the author’s impressive 30 years of experience in the field.By the end of this systems engineering book, you'll be able to apply modern model-based systems engineering techniques to your own systems and projects.What you will learnStudy the three evils of systems engineering: complexity, ambiguous communication, lack of understandingLearn how to deploy MBSE using the Trinity approachReceive invaluable information about the philosophy of modeling from a seasoned professionalUnderstand the MBSE life cycle and how design, verification, and validation fit into itExplore processes and concepts such as activities, stakeholders, and resourcesDiscover how needs fit into the life cycle and how to comply with relevant processesGain a deeper understanding of how to model effectively and efficientlyWho this book is forThis book is for aspiring systems engineers, engineering managers, or anyone looking to apply systems engineering practices to their systems and projects. While a well-structured, model-based approach to systems engineering is an essential skill for engineers of all disciplines, many companies are finding that new graduates have little understanding of MBSE. This book helps you acquire this skill with the help of a simple and practical approach to developing successful systems.

For any organisation to be successful in an increasingly competitive and global working environment, it is essential that there is a clear understanding of all aspects of the business. Given that no two organisations are exactly alike, there is no definitive understanding of exactly what these aspects are as they will depend on the organisation's nature, size and so on. Some of the aspects of the business that must be considered include: process models, process descriptions, competencies, standards, methodologies, infrastructure, people and business goals.It is important that these different aspects of the business are not only understood, but also that they are consistent and congruent with one another. The creation of an effective Enterprise Architecture (EA) provides a means by which an organisation can obtain such an understanding.This book looks at the practical needs of creating and maintaining an effective EA within a twenty-first-century business through the use of pragmatic modelling. The book introduces the concepts behind enterprise architectures, teaches the modelling notation needed to effectively realise an enterprise architecture and explores the concepts more fully through a real-life enterprise architecture.

This book provides a hands-on introduction to model-based requirements engineering and management by describing a set of views that form the basis for the approach. These views take into account each individual requirement in terms of its description, but then also provide each requirement with meaning by putting it into the correct 'context'. A requirement that has been put into a context is known as a 'use case' and may be based upon either stakeholders or levels of hierarchy in a system. Each use case must then be analysed and validated by defining a combination of scenarios and formal mathematical and logic-based proofs that provide the rigour required for safety-critical and mission-critical systems.The book also looks at the crucial question of modelling notations for requirements modelling and includes discussions on the use and application of SysML, text and tabular formats.Pragmatic issues, such as tailoring the approach for short, non-critical projects to massive, mission-critical projects is discussed to show how the techniques introduced in the book can be applied on real-life projects and systems. The use of multiple tools will also be discussed, along with examples of how an effective process can lead to realisation by any tool.
