The Lifecycle Modeling Language (LML) is an open-standard modeling language designed for systems engineering. It supports the full lifecycle: conceptual, utilization, support and retirement stages. Along with the integration of all lifecycle disciplines including, program management, systems and design engineering, verification and validation, deployment and maintenance into one framework.〔(【引用サイトリンク】title=LML Specification )〕 LML was originally designed by the LML steering committee. The specification was published October 17, 2013. The purpose behind the language is to replace predecessor languages, such as UML and SysML that overcomplicate the systems engineering process. LML uses common language to define its modeling elements such as entity, attribute, schedule, cost, and relationship.〔(【引用サイトリンク】title=About Lifecycle Modeling Language )〕 == Overview == LML communicates cost, schedule and performance to all stakeholders in the system lifecycle. LML combines the logical constructs with an ontology to capture information. SysML is mainly constructs and has a limited ontology, while DoDAF MetaModel 2.0 (DM2) only has an ontology. Instead LML simplifies both the constructs and ontology to make them more complete, but still easier to use. There are only 12 primary entity classes. Almost all of the classes relate to each other and themselves with consistent words, i.e., Asset performs Action. Action performed by Asset.〔Dr. Steven Dam and Dr. Warren Vaneman, ("Lifecycle Modeling Language Tutorial" ), ''Presentation at SEDC 2014''2014-04-06〕 SysML uses object oriented design, because it was designed to relate systems thinking to software development. No other discipline in the lifecycle uses object oriented design and analysis extensively. LML captures the entire lifecycle from cradle to grave.〔 Systems Engineers have identified complexity as a major issue.〔 LML is a new approach to analyzing, planning, specifying, designing, building and maintaining modern systems. LML focuses on these 6 goals: 1. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lifecycle Modeling Language」の詳細全文を読む スポンサード リンク
