The systems modeling language ‎(‎sysml‎)‎ extends uml with powerful systems engineering capabilities for modeling a wider spectrum of systems and capturing all aspects of a system‎'‎s design‎.‎ Sysml distilled is the first clear‎,‎ concise guide for everyone who wants to start creating effective sysml models‎.‎ ‎(‎drawing on his pioneering experience at lockheed martin and nasa‎,‎ lenny delligatti illuminates sysml‎'‎s core components and provides practical advice to help you create good models and good designs‎.‎ Delligatti begins with an easy‎-to‎-understand overview of model‎-based systems engineering ‎(‎mbse‎)‎ and an explanation of how sysml enables effective system specification‎,‎ analysis‎,‎ design‎,‎ optimization‎,‎ verification‎,‎ and validation‎.‎ Next‎,‎ he shows how to use all nine types of sysml diagrams‎,‎ even if you have no previous experience with modeling languages‎.‎ A case study running through the text demonstrates the use of sysml in modeling a complex‎,‎ real‎-world sociotechnical system‎.‎ Modeled after martin fowler‎'‎s classic uml distilled‎,‎ delligatti‎'‎s indispensable guide quickly teaches you what you need to know to get started and helps you deepen your knowledge incrementally as the need arises‎.‎ Like sysml itself‎,‎ the book is method independent and is designed to support whatever processes‎,‎ procedures‎,‎ and tools you already use‎.‎ Coverage includes * why sysml was created and the business case for using it* quickly putting sysml to practical use* what to know before you start a sysml modeling project* essential concepts that apply to all sysml diagrams* sysml diagram elements and relationships* diagramming block definitions‎,‎ internal structures‎,‎ use cases‎,‎ activities‎,‎ interactions‎,‎ state machines‎,‎ constraints‎,‎ requirements‎,‎ and packages* using allocations to define mappings among elements across a model* sysml notation tables‎,‎ version changes‎,‎ and sources for more information
