Branch

The Branch object directs an incoming entity to a destination that is chosen from a list of alternatives.

The value for the Choice keyword determines the destination that is chosen: 1 = first branch, 2 = second branch, etc.  The input to Choice can be a constant value, a DiscreteDistribution, a TimeSeries, or an Expression.  The use of an Expression allows the choice to be made based on the Attributes of the incoming entity.
