ILOG Optimization Powers Spain’s Metro Bilbao Timetable Planning System
New System Improves Response Time and Delivers Better Service to Subway Passengers
MADRID – November 19, 2002 - ILOG® (NASDAQ: ILOG; Euronext; SICOVAM: 006673), the leading supplier of enterprise-class software components, today announced that its ILOG Solver™ and ILOG CPLEX® optimization components have been deployed to power Metro Bilbao’s real-time train scheduling system. This change will help make the metro, which connects more than one million inhabitants of Spain’s Basque region, among the most reliable in Europe. In addition, by using ILOG components, Metro Bilbao was able to reduce the amount of time it takes to build and update a schedule from one day to one hour.
Built by the transportation division of Thales Information Systems, one of Spain’s leading IT systems integrators, the scheduling system, called Transport Schedules Planner (GOT), relies on ILOG software to automatically update train schedules whenever traffic fluctuates - whether the fluctuations are due to unforecasted passenger flows or to any unpredictable traffic incidents. The result is a more responsive system that provides improved reliability and on-time performance for the metro.
“The Metro Bilbao project was founded on the philosophy of providing high quality, state-of-the-art and reliable transportation for its millions of passengers each year,” said Josu Irureta, Transportation Division Manager, Thales Information Systems. “The goal could only be met through more flexible operations and scheduling, which is enabled by ILOG software, providing Metro Bilbao with improved agility and service delivery.”
ILOG optimization tools power five unique parts of the GOT system. The Vehicle Planner is responsible for complete planning of the train routes with specific diagrams by day, week, and event. After the timetables are established, the Crew Scheduling module defines duties to cover vehicle schedules. The Roster Generation then prepares periodic crew assignments, while the Employee Assignment module defines specific shifts according to employee information, roster rotation, rules of seniority and collective labor agreements. The last module, called Costs, evaluates the operational cost of each solution. As a result of the whole system, drivers match to trains and draw up an exact work shift calendar that is adapted to real service needs.
This deployment further extends the penetration of ILOG’s products with the leading passenger rail systems in Europe, including RENFE (Spanish railways), SNCF (French railways) and Deutsche Bahn (German railways).
