Information
This information is part of the Business Simulation Library (BSL). Please support this work and ► donate.
Using the →ExogenousChange component from the SourcesOrSinks package, this component allows to model linear (additive) change at a given a constant rate or at an exogneous rate given by the input u_rate.
The process by default is active over the whole simulation run, but can be restricted to an on-off period using tc = TimingChoices.period and the parameters startTime and stopTime. Any given rate—rate or u_rate—can be modified by multiplication with an optionally given input u.
