BrokenTransition

The inflow to B is proportional to the outflow from A

Diagram

Information

This information is part of the Business Simulation Library (BSL).

This is the classical structure for a broken flow from stock A to stock B, where the rate of outflow is given for stock A. A's outflow will flow into a →Cloud and accordingly, there will be an inflow to stock B which is given by:

rate of inflow to B = rate of outflow from A × factor of proportionality

Here the factor of proportionality will be given as amount of B per amount of A, so that the resulting inflow to B will have proper units [amount of B per second].

Notes

Jim Hines [6, p. 16] notes, that "in an aggregated model of a supply chain there will be a change of units and a conceptual break in the transition from raw materials inventory to work in progress."
