Jul 03, 2017 · SysML v1 support this capability, but does require an additional concept called an adjunct property to establish correspondence between the activity decomposition and the actions in an activity diagram. In SysML v2, behavior decomposition should apply the same modeling concepts that apply to structure decomposition in order to simplify and ...

SysML Activity Diagrams. The purpose of an Activity Diagram in SysML is to specify the transformation of inputs to outputs through a controlled sequence of actions. An Activity decomposes into Actions. In activity diagrams, the Object Nodes (i.e. Pins and Parameter Nodes) correspond to buffers to place input and output tokens.
SysML Activity Diagram | Enterprise Architect User Guide
An activity diagram with item (input/output) flows shown between activities (using object nodes) would represent the operational activities. If control flows are also shown on activity diagram, then OV-5 and OV-6c have been combined into one product. Hierarchy of operational activities can be modelled in a SysML Activity Hierarchy.

A single concept: an activity generates an output that is an input to another activity. SysML is using two entities to represent this single concept with different syntax in two views. This situation can lead to costly engineering errors of inconsistency in the modeling of complex systems and can force vendors to apply checking routines to ...

Use of Activity Diagrams. In some cases, an activity diagram can add value by helping to define, clarify, and complete the flow of events in the use case. IBM Rational Software Architect can be used to create activity diagrams. A good practice is to create activity diagrams for complex use-cases (containing several alternative or exceptional ...

Requirements as written statements are always less precise and open to interpretation than say a SysML activity diagram. The use of SysML can be seen as an exercise in requirement analysis. That is trying to discover the requirements for a system so that it can be built. It is sometimes thought that requirements need to exist before a model can ...

The most oft-cited diagram that garnered this reaction was the block definition diagram, which is a systems-flavored descendant of the UML class diagram. At least two of the major texts on SysML (Friedenthal, 2008; Holt, Perry, 2007) present this diagram type first, showing how the software meta-model and practitioner mindset of UML is in ...
