The constraint X₁₃ + X₂₃ − X₃₄ ≥ 50 indicates that A) 50 units are required at node 3. B) 50 units will be shipped from node 3. C) 50 units will be shipped in from node 1. D) 50 units must pass through node 3.

Question

Quizplus · Accepted Answer

The constraint X₁₃ + X₂₃ − X₃₄ ≥ 50 is a flow conservation constraint for node 3. It states that the total flow into node 3 (from nodes 1 and 2) minus the flow out of node 3 (to node 4) must be greater than or equal to 50. This means that at least 50 units are needed at node 3 to satisfy the demand of node 4. Therefore, choice A is the best choice.
