In transportation model problems the destination:Group of answer choicesis not a concern in transportation models.has a fixed demand for the product.determines if the objective function should be minimized or maximized.has an unbounded demand for the product.

For assignment model problems, what conditions are placed on the demand?Group of answer choicesThere are no conditions placed on the demand in assignment models.Demand is not a concern in transportation models.Demand must equal supply.Demand at each destination is limited to one unit.

In a transportation model, if demand is greater than supply, which constraints change?Group of answer choicesThere is no change to constraints for this situation.Objective function coefficients are scaled to sum to one.Demand constraints are less-than-or-equal-to and supply constraints hold with equality.Supply constraints are less-than-or-equal to and demand constraints hold with equality.
