Loading Types . Rapid loaders . Mechanical loaders . Drop loads . Location . Coal field system . DC area and Diesel served ‘branch’ line . GFB system . Grootegeluk . Natal Midlands . ‘En routes’ . Panbult (between Vryheid and Ermelo) . Capability . Jumbo . Small [100 and 50] . [Jumbo as small] 4 Transnet Freight Rail Required . Schedule for week . Fixed schedule portion .Variable portion .Balanced and evenly spaced .Optimised . Rescheduling capability for least impact recovery 5 Transnet Freight Rail Scheduling Requirement . Train schedule must: . satisfy the varying demand by and special requirements of the mines; . conform to the agreed operating philosophy of rhythm and balance without bundling . consider the availability and position of rolling stock as well as unavailability of infrastructure . be derived within a short period without dependence on individuals 6 Transnet Freight Rail Rescheduling requirement . Existing schedule . There have been either . changes in execution – some planned trains did not run or ran in wrong slots . changed demands from mines or revised occupations . Produce a revised schedule given the following input . The detail of trains actually ran (i.e. the incident recording or ‘per train monitoring’ . The changed demand .the currently planned schedule for the rest of the week plus additional demand . in addition a revised number of trains, feeder occupation and mainline occupation . A revised schedule should be produced (if possible) to move the remaining demand with the least impact on existing schedule 7 Transnet Freight Rail CURRENT FUNCTIONALITY . Able . Unable . Available capacity . Does not cater for the location of locomotives . Next weeks demand . Does not have a parameter for the maximum Inputs . Drop off information number of trains at the yards (EML, VYD and . Mainline slots RBCT) . Feeder line information . Mainline and Vryheid train information . Crewing information . Mine constraints . Mine travel and dwell times . Feeder Occupations . Mainline maintenance . Mainline travel and dwell times Transition information for rescheduling . Business rules relating to wagon configuration . Balancing logic . Balanced Schedule for Mainline and to mines . Does not allow the scheduling of sets that . Balanced Schedule for the Natal trains are larger than 100 wagons up to the mines Generates . Daily services . Does not balance schedule through . Scheduled throughput consideration of availability of locos . Result wagons – detail log of planned set (especially light loco scenario) movements . Does not generate graphical representation . Indicate unallocated feeders of schedule . Rescheduling of trains 8 Source: Richards Bay Corridor team Transnet Freight Rail Detail Requirements in Scheduling (1) . Demand by the mine: . Number of loads per week (eg. 190 trains to 40+ mines) . Type and size of load (Jumbo or Small (100 or 50 sets) or Jumbo loaded as small) . Days when required (or any day) . Maximum loads that can be accepted per day OR “At least” number of loads to be allocated per day . Days or period within a day when trains can not be accepted by the mine. 9 Transnet Freight Rail Maximum Maximum Maximum Maximum Maximum Maximum Maximum number of number of number of number of number of number of number of Total Short Train type & trains trains trains trains trains trains trains MineID Code Mine trains code mine #wagons Monday Tuesday Wednesday Thursday Friday Saturday Sunday 1 J VST TSELENTIS - VSTJ10099999999999999 2JS VST TSELENTIS - VSTJ10099999999999999 3 S VST TSELENTIS 4 VST S100 0 0 1 0 1 1 1 4S5 VST TSELENTIS - VST S50 99 99 99 99 99 99 99 5J KOY KOORNFONTEI 5 KOY J100 0 0 0 1 2 1 1 6JS KOYKOORNFONTEI - KOYJ10099999999999999 7S KOY KOORNFONTEI - KOYS10099999999999999 8S5 KOYKOORNFONTEI - KOY S50 99 99 99 99 99 99 99 9J MED MIDDELBURG 16 MED J100 3 3 3 3 3 3 3 10 JS MED MIDDELBURG - MEDJ10099999999999999 11 S MED MIDDELBURG - MEDS10099999999999999 12 S5 MED MIDDELBURG - MED S50 99 99 99 99 99 99 99 "must be" "must be" "must be" "must be" "must be" "must be" "must be" Tonnage per feeders feeders feeders feeders feeders feeders feeders train Monday Tuesday Wednesday Thursday Friday Saturday Sunday 83000000000 58000000000 58000000000 29000000000 83000000000 58000000000 58000000000 29000000000 83000000000 58000000000 58000000000 29000000000 10 Transnet Freight Rail Mine constraint MINE LOADING AVAILABILITY = Mine not available from that time onwards Standby: Sampie van den BAH : 083 303 8931 reclaiming time (days) 0.1 0.1 0.1 0.5 0.3 1.0 0.5 0.1 0.1 0.1 0.1 0.1 1.0 0.5 0.2 0.5 0.5 0.1 0.2 0.5 0.2 0.1 2.0 0.5 0.5 0.2 0.2 requested # trains 10241514515516181022632 27559112134 RBCT code BNK RLT GH GRN GGK NCD EKB OPT KFT MID VDD RS BSP WAL TFT WCC PHX SWB TAV UTK FZO ATC SBK ANT OB TWI VST BYY LDY GHM GSE GGK BZR EIY PSH KOY MED VYF RSY BSX WAL MNR SRW PHX SWD OUT UIT FOR ATC SBK ANT OBK TIT VST Mon 00:00 01:00 02:00 03:00 04:00 05:00 06:00 11 Transnet Freight Rail Detail Requirements in Scheduling (2) .Mine details .
