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 594 Inventory 297 Rate 99 Price BerthLimit 1 PortFee 38 maxAmt 300 minAmt 35 C2R ratio 6 ----- Port Table For Region 1 ---- Port0 Port1 Port2 Capacity 351 510 312 Inventory 168 255 156 Rate -39 -34 -26 Price 5 5 5 BerthLimit 1 1 1 PortFee 57 58 66 maxAmt 300 300 259 minAmt 50 35 20 C2R ratio 9 15 12 ----- MinDurationInRegionTable ---- LR0r0 DR0r1 VC0 0 2 MinDurationInRegionTable(vc,r) = the minimum duration a vessel in vessel class vc must stay in region r. ----- FullDistanceMatrix ----- 0 1 2 3 0 0.00 5792.83 5730.94 5663.71 1 5792.83 0.00 326.10 338.92 2 5730.94 326.10 0.00 67.42 3 5663.71 338.92 67.42 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 Type Term Term Term Term Term Term Term Class 0 0 0 0 0 0 0 Capacity 300 300 300 300 300 300 300 ----- MinMaxInterRegionalTravelTimes ----- Vessel_Class_0 DR0 LR0 ( 9, 9) 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 0 0 9 9 9 1 9 0 1 1 2 9 1 0 1 3 9 1 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 0 38 491 487 490 1 472 57 82 91 2 467 81 58 71 3 462 82 63 66 FullTravelCostMatrixForClass(vc,i,j) = travel cost for a vessel in vessel class vc to travel from port i to port j.
