In a linear programming formulation of the transshipment problem, if the total supply is greater than the total demand, then all constraints could just be $\geq$ type constraints.

Question

Quizplus · Accepted Answer

In a linear programming formulation of the transshipment problem, if the total supply exceeds total demand, the system must include both $\geq$ (or $\leq$) type constraints for supply or demand limitations and equality constraints to ensure the conservation of flow through the network. The $\geq$ type constraints alone cannot ensure that all supplied goods are properly accounted for in the network flow.
