MODEL CONCEPTS
Modeling guidelines and Practices Application of modeling guidelines and practices.
6% ORGANIZING A SYSTEM MODEL USING THE FULL SET OF SYSML CONSTRUCTS
Building A Package Diagram Using the Full Set of SysML Constructs
Package and element import, defining and using view and viewpoint, building and using model libraries, as well
as awareness of assessment criteria (e.g., structured queries) and activities.
6% BUILDING A REQUIREMENTS MODEL USING THE FULL SET OF SYSML CONSTRUCTS
Building A Requirements Diagram Using the Full Set of SysML Constructs
Specialized requirements (SysML Annex C: functional, interface, performance, physical and design constraints),
establishing requirements traceability (derive, verify, satisfy, refine, trace and containment), tracing requirements in tables and matrixes, representing verification and testing, test context as well as test case.
Building A Use Case Model Using the Full Set of SysML Constructs
Relating use cases to behavioral models – activity diagrams and state machines, and relating use cases to requirements.
10% BUILDING A STRUCTURAL MODEL USING THE FULL SET OF SYSML CONSTRUCTS
Building the Block Definition Diagram
Adding Block Features: Receptions, ordered and unique collections, read only properties, property redefinition,
constraint (reference to parametrics below), distributed properties. Block Relationships: Shared vs composite
aggregation (white vs black diamond), association blocks and generalization sets. Value Types: Enumerations,
structured value types (“position vector” with XYZ structure). Blocks and Behavior: Classifier behavior (See
Friedenthal), owned behaviors, activity hierarchies on bdds. Defining instances.
29% BUILDING A PARAMETRIC MODEL USING THE FULL SET OF SYSML CONSTRUCTS
Building the Internal Block Diagram
Block Properties: Creating a property specific type and notation for part multiplicities on ibd’s. Ports: Flow Ports:
Flow specifications and properties, conjugated ports, and compatibility rules including item flows and ports.
Standard Ports: Defining required and provided interfaces, typing a port with required and provided in terfaces
(i.e., with a provided interface and with a classifier with use/realize relationship). Port delegation (for both flow
ports and standard ports). Connectors: Nested connector ends, item flows/item properties, conveyed
classifiers, typing item properties, ownership of item properties, and connector properties.
How To Use Constraints in SysML to Model System Analyses
Defining Constraints on A Block Definition Diagram Using the Full SysML Feature Set
Nesting of constraints, trade study support (Annex E.4), measures of effectiveness, objective functions,
alternatives, and constraining flows.
11% BUILDING A BEHAVIORAL MODEL USING THE FULL SET OF SYSML CONSTRUCTS
How To Use SysML to Model System Behavior
Building An Activity Diagram Using the Full Set of SysML Constructs
I/O Flow: Optional vs. required, streaming, rates (continuous and discrete), no buffer, overwrite, token ordering
(FIFO, LIFO, etc.), data store/central buffer, object node state, parameter set, and probabilities. Control Flow:
Control Operators: Flow final, and advanced control operations (decision input/ join specification). Control pins
and interruptible regions. Actions: Primitive actions. Constraints: Pre/post conditions and defining properties on activities.
Building A Sequence Diagram Using the Full Set of SysML Constructs
Messages, Lifelines: Selectors, lifeline decomposition and activations (including nested). Interaction Operators:
Advanced interaction operators, combining interaction operators and nesting interaction operators. Interaction
Decomposition: Interaction use or references and gates. Constraints: Observations and timing constraints and state invariants.
Building A State Machine Diagram Using the Full Set of SysML Constructs
Understanding that a SM represents the states of a block (Friedenthal). Transitions: Graphical transition
notation, internal transitions and deferred events. State Hierarchy: Composite states and orthogonal composite
states. Pseudo States: Junction state, choice, history states – shallow, deep, fork and join, entry and exit points,
and terminate nodes. Nested State Machines: Submachine states. Connection points.
