Balance Flow Network Models

Applies the methods of Allesina and Bondavalli (2003) for balancing flow network models.

Usage

balance(x, method = c("AVG2", "AVG", "IO", "OI", "I", "O"), tol = 5)

Arguments

x

A network object.

method

Methods for model balancing, see Allesina and Bondavalli (2003).

tol

Percent error tolerance used in the steady state check prior to balancing.

Value

Returns a network object with a balanced flow network model.
