The true average depends on the number of time periods considered in the planning horizon. Note: C2R ratio = Average capacity-to-rate ratio. The smaller the number, the more frequent visits must occur, i.e., the harder the instance. ----- Port Table For Region 0 ---- Port0 Capacity 655 Inventory 327 Rate 131 Price BerthLimit 1 PortFee 84 maxAmt 300 minAmt 75 C2R ratio 5 ----- Port Table For Region 1 ---- Port0 Port1 Port2 Port3 Capacity 344 480 390 312 Inventory 172 240 195 156 Rate -43 -32 -30 -26 Price 4 4 4 4 BerthLimit 1 1 1 1 PortFee 14 14 22 28 maxAmt 180 265 195 180 minAmt 65 50 45 45 C2R ratio 8 15 13 12 ----- MinDurationInRegionTable ---- LR0r0 DR0r1 VC0 0 2 VC1 0 2 VC2 0 2 MinDurationInRegionTable(vc,r) = the minimum duration a vessel in vessel class vc must stay in region r. ----- FullDistanceMatrix ----- 0 1 2 3 4 0 0.00 7372.21 6988.66 7352.95 7159.23 1 7372.21 0.00 456.45 166.86 564.42 2 6988.66 456.45 0.00 374.25 771.62 3 7352.95 166.86 374.25 0.00 712.06 4 7159.23 564.42 771.62 712.06 0.00 FullDistanceMatrix(i,j) = distance (km) from port i to port j. ----- Vessel Table ---- Vessel_0 Vessel_1 Vessel_2 Vessel_3 Vessel_4 Vessel_5 Vessel_6 Vessel_7 Vessel_8 Vessel_9 Vessel_10 Vessel_11 Type Term Term Term Term Term Term Term Term Term Term Term Term Class 0 0 0 0 1 1 1 1 2 2 2 2 Capacity 300 300 300 300 250 250 250 250 200 200 200 200 ----- MinMaxInterRegionalTravelTimes ----- Vessel_Class_0 DR0 LR0 (11,12) Vessel_Class_1 DR0 LR0 (10,11) Vessel_Class_2 DR0 LR0 (10,10) entry(vc,lr,dr) = a tuple containing the minimum and maximum travel time (number of periods) for a vessel in vessel class vc to travel from loading region lr to discharging region dr. ----- FullTravelTimeMatrixForClass ----- Vessel_Class_0 0 1 2 3 4 0 0 12 11 12 11 1 12 0 1 1 1 2 11 1 0 1 2 3 12 1 1 0 2 4 11 1 2 2 0 Vessel_Class_1 0 1 2 3 4 0 0 11 10 11 11 1 11 0 1 1 1 2 10 1 0 1 2 3 11 1 1 0 2 4 11 1 2 2 0 Vessel_Class_2 0 1 2 3 4 0 0 10 10 10 10 1 10 0 1 1 1 2 10 1 0 1 2 3 10 1 1 0 1 4 10 1 2 1 0 FullTravelTimeMatrixForClass(vc,i,j) = travel time (number of periods) for a vessel in vessel class vc to travel from port i to port j. ----- FullTravelCostMatrixForClass ----- Vessel_Class_0 0 1 2 3 4 0 84 566 538 573 564 1 636 14 48 34 70 2 608 48 14 50 85 3 635 26 42 22 81 4 620 56 71 75 28 Vessel_Class_1 0 1 2 3 4 0 84 574 545 580 572 1 644 14 48 34 70 2 615 48 14 50 86 3 642 26 42 22 82 4 628 56 72 76 28 Vessel_Class_2 0 1 2 3 4 0 84 581 552 588 579 1 651 14 49 34 71 2 622 49 14 50 87 3 650 26 42 22 82 4 635 57 73 76 28 FullTravelCostMatrixForClass(vc,i,j) = travel cost for a vessel in vessel class vc to travel from port i to port j.
