Transition

Flow from stock A to stock B at a given rate

Information

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

This is the prototypical unidirectional flow of matter from stock A to stock B at a given rate. The rate can be either constant (rate) or given by the continuous input u.

Notes

Since this is a unidirectional flow the rate of flow will always be set to zero (causing an event) if the given rate of transition is a negative value.
