Chapter 8 Modeling Flow-Based Behavior with Activities

  This chapter describes concepts needed to model behavior in terms of the flow of inputs, outputs, and control using an activity diagram. An activity diagram is similar to a traditional functional flow diagram, but with many additional features to precisely specify a behavior.

8.1. Overview

 In SysML, an activity is a formalism for describing behavior that specifies the transformation of inputs to outputs through a controlled sequence of actions. The activity diagram is the primary representation for modeling flow-based behavior and is analogous to the functional flow diagram that has been widely used for modeling systems. Activities provide enhanced capabilities over traditional functionalflow ...
