LRDSS - Strengths t One of the few Large Scale Analytical Planning tools used by Indian Public Sector t Major aspects covered: R Opportunity: Forecasting business volume & price R Threats: Analyzing competition R Strength/Weakness: Rail technology evaluation R Micro level: Sectional bottleneck analysis R Plan generation R Alternate investment scenario analysis R Project Cost, Revenue & Cash Flow report t Improvement in data quality, backed up by surveys t “Best of breed” analytical approaches t Excellent team Copyright: Tata Infotech Limited 3

LRDSS – enhancements? t System Verification: R Monitoring: Compare prediction against actual Success report on projects evaluated R Valuation: Estimate Ro. I of LRDSS R Goal: LRDSS as a core input to Rail Budget t Some additions/changes R Workflow S. . Z. . B for Business/Price Forecasts R “Rail Technology” to include “ICT” option R “Force multiplication” of Rs 25 KB Loco/wagons 1%=$100 M R Use automated train planning w/ data logger inputs R R RAILS does not optimize (only feasibility check) Use Furness approach also for capacity analysis MINOS is outdated, use GA-based engines Linearize all models Copyright: Tata Infotech Limited 4

Commentary– Phase findings t ’ 96 Phase I report: R Data unavailability – impacts: delay, report quality R “Ambitious” with 3 modules (bugs, integration, . . ) R China Rail 1990 study quoted, but reorganization? Copyright: Tata Infotech Limited 6

Commentary– Phase findings t ’ 00 Phase II report: R Declining profitability – make IR unviable? ? R How improve wagon availability? (customer need) R How reduce ops slack? (30% capacity here) R How to “tighten” loco timetables? (capacity issue) R Capacity only answer to bottleneck? ? R Golden Quadrilateral? ? R New trucking technology & improved road load? ? R Improved sectional “capacity” measurement? ? R New ops practices? e. g. heavy MUXing for freight R “Expert Advisors” were suggested for IT – where? R MIS systems were suggested – lack integration Copyright: Tata Infotech Limited 7

IT element in LRDSS • LRDSS is NOT an “IT” project (IIT/IIM Depts) 1. The IT components are secondary 2. The Planning formulation is primary 3. “IT” is not a “Rail Technology” in LRDSS • There are interesting tools/processes 1. Sectional capacity analysis 2. Train Timetabling 3. Train Monitoring & Planning 4. Loco/wagon repositioning 5. Customer Survey Analysis 6. Demand & Price Forecasting Copyright: Tata Infotech Limited 27
