Penalty added to the overall cost to traverse the affected arc. (cij/m)*1.5 = 4232A terrorist attack is an actual attack which renders the affected arc inoperable. </p> <p>Zero Threats on NetworkZero Threats on Network-------452bbbjbbjbjbjb-452-4523155652581809621900</p> <p>Three Threats on NetworkThree Threats on Network31-258180 9655219 65-452-4520</p> <p>Five Threats on NetworkFive Threats on Network 31258 180 96 5521965-452-4520</p> <p>One Attack on NetworkOne Attack on Network000000000000-452-452 650</p> <p>Two Attacks on NetworkTwo Attacks on Network-452-452219000000000000250 0</p> <p>Three Attacks on NetworkThree Attacks on Network00000000000000000000-452-452 65 55219 31 258 18096</p> <p>MAP 2</p> <p>RecommendationsEliminate or increase capacity at choke pointsIncrease the number of Supply nodes Incorporate short lines &amp; regional linesAlternative means of transportation</p>
