To construct a lower bound for nodal recourse, assume a projected value, y^t
(i) of yt (i) (as, e.g., an average of incoming and outgoing loads). Find an expression (in terms of the demand distributions on the ranked full load alternatives) for the expected value (assuming linearized future costs) of an additional vehicle beyond yt (i) . Show that this procedure gives a lower bound on (5.8) when t = 1
