The Real output y is obtained by dividing the current amount in a material stock
u_level by the (positive) rate of its outflow
u_rate. According to Little's Law—a famous result from queueing theory—the output y will be equal to the mean time of residence in the stock if the system is in equilibrium.
u_level) and the rate of outflow (
u_rate) have to be positive; negative values will be assumed to be zero.
Constants.infwill be used to obtain the output.
