BrokenTransitionThe inflow to B is proportional to the outflow from A 
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].
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."
rate 
Value: unspecified Type: Rate (1/s) Description: Constant rate of outflow for the stock A 

factor 
Value: 1 Type: Amount (each) Description: Constant factor of proportionality to be multiplied with the outflow from A (default = 1 each [per 1 each]) 
hasConstantFactor 
Value: false Type: Boolean Description: = true, if the factor is to be given by the constant parameter 
hasConstantRate 
Value: false Type: Boolean Description: = true, if the outflow rate for A is to be given by the constant parameter
