In SysML, one critical concept is assigning behavioral features (operations) to a system or a block. These operations represent specific actions or behaviors that the system can perform when invoked. When an operation is executed, the system carries out the defined behavior to produce some kind of output. This output could be data, a computed value, or even a visualization like a graph. For example, imagine you have a system called “Communication and Data Handling”. One of its operations could be “Generate a Position Report”, which calculates position with respect to time. • When an external entity ( a user or another system) provides the required input (such as speed), the Communication and Data Handling system processes this input and produces an output (time vs. position graph or a dataset). • This operation encapsulates the logic for acquiring the necessary data, performing computations, and generating the required output.
