Master-Slave Constraints

Using zero/one variables, we can control the range of values that other variables take. Suppose that $x_{AB}$ (the amount shipped from to ) is either 0 (we don't ship from to ) or between 20 and 100 (we ship from to with limits specified by the transportation company). We introduce a new binary (0-1) variable $z_{AB}$ that is 1 if there is a shipment from to and 0 otherwise. Then we can use a master-slave constraints to let $z_{AB}$ control $x_{AB}$
