Model organization¶

Product Package register
Every file of the model with its package, the CoSMA layer it belongs to, what it contains, and its size.

The CoSMA framework¶

CoSMA (Complex System Modeling and Architecting) is the framework from Airbus Central R&T that structures this model. It separates five layers of concern, each answering one question:

Layer	Question	In this model
Purpose	Why does the system exist?	stakeholders, concerns, needs, capabilities, mission goals
Operational	When do things happen?	mission phases and the operations performed in them
Functional	What must the system do?	the function hierarchy, independent of implementation
Logical	Which abstract parts do it?	logical components that perform the functions
Technical	How is it built?	hardware designs, interfaces, as-flown vehicles, crew

CoSMA uses no profile or stereotypes: the model defines no metadata types of its own. CoSMAPackage defines ordinary SysML definitions (Stakeholder, Mission, Function, HardwareComponent, …) and the model specializes them with :>, so the framework is visible to any SysML v2 tool.

Product CoSMA metamodel register
Each CoSMA base type, its SysML kind, and how many model definitions specialize it and usages are typed by it.
Use it to see which framework concepts the model populates, and which are still empty.

Product CoSMA traceability map
The framework's concepts arranged by layer, with the links the model actually contains between them and how many of each.
Use it to follow a thread across the layers, for example from a stakeholder need down to the hardware that meets it.

Requirements are in the bottom row (dashed boxes); dashed arrows are refinement and satisfaction links. Follow the arrows backwards, from left to right, to trace a need down to hardware: a capability refines a stakeholder need; a mission requirement refines the capability and is satisfied by an operation; a function refines the operation and satisfies a functional requirement, which refines the mission requirement; a logical component performs the function; and a technical requirement refines the functional requirement and is satisfied by a hardware component.

File dependencies¶

Product File dependency matrix
A design structure matrix of the files: a mark in row A, column B means file A refers to elements of file B.
Use it to judge the impact of changing a file (read its column) and what a file needs to be understood (read its row).

Most depended on: CoSMAPackage (19 files), CoSMAQuantitiesAndUnitsPackage (10 files), TechnicalComponentsPackage (6 files).
Most dependent: MissionPackage (uses 9), Apollo11MissionExecutionPackage (uses 8), AnalysisPackage (uses 7).
Used by no other file: MissionSpecificationPackage, FunctionSpecificationPackage, SystemSpecificationPackage, AnalysisPackage, ProgramPackage, CoSMAViewsPackage, Apollo11Model.

Product Standard-library usage
The SysML v2 standard-library files the model refers to, and how many model files use each.
Use it to know which libraries a tool must load to work with the model.

Element statistics¶

Product Element kinds
How many elements of each SysML kind the model contains.
Use it to gauge the model's size and style (for example, how much is requirements versus structure).

Ref (reference usages, 931) are features declared without a kind keyword: values inside metadata annotations such as @Rationale (294), the ends of successions, transitions and connections (253), and parameters of action and calculation definitions (188), among others.
