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.

In an unbalanced transportation model, supply does not equal demand, and supply constraints must have ≤ signs.Group of answer choicesTrueFalse

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.

f both prices increases by 50%Group of answer choicesbudget constraint will be unchanged.slope of the budget constraint stay the same.slope of the budget constraint will decrease.budget constraint will shift outward in a parallel fashion.

Nonnegativity constraints ensure that _____.Group of answer choicesthe solution to the problem will contain only nonnegative values for the decision variablesthere are no inequalities in the constraintsthe problem modeling includes only nonnegative values in the constraintsthe objective function of the problem always returns maximum quantities PreviousNext
