Answer: Total transportation cost while meeting supply and demand.
- A Total profit earned across all supply routes
- B Total transportation cost while meeting supply and demand
- C The number of warehouses included in the supply network
- D Travel time only, ignoring cost considerations entirely
Correct answer: B. Total transportation cost while meeting supply and demand
Explanation: A transportation problem minimizes the total cost of moving goods from sources (factories or warehouses) to destinations (markets), subject to supply and demand constraints.
The feasible region (shaded) is bounded by the constraint lines; the fundamental theorem of LPP guarantees the optimal value of the objective function occurs at one of the corner points (O, A, B, C), so only these need to be checked, not the entire region.
Concept context
Optimizing a linear objective function subject to linear constraints using the graphical corner point method.
