Decline

A stock is drained at a given rate

Information

This information is part of the Business Simulation Library (BSL). Please support this work and ► donate.

Decline can be used to model an outflow from a stock into a sink with infinite capacity outside the border of the system in focus. The rate of flow can either be set by the real input u (hasConstantRate = false) or by the parameter rate (hasConstantRate = true).

Notes

The rate of flow has to be non-negative as the connected stock should never be filled. A negative rate of flow will be set to zero internally.

If the connected stock might also be filled, →ExogenousChange should be used.
