Transportation Operator Combines Multiple ILOG Technologies To Achieve Operational Efficiency Goals

SINGAPORE – November 19, 2003 – ILOG® (NASDAQ: ILOG; Euronext: ILO, ISIN: FR0004042364), a leading supplier of software components and services, today announced that Singapore’s Trans Island Bus Services (TIBS), a company listed on the main board of Singapore Stock Exchange, has acquired and deployed multiple ILOG software products into their dispatching systems in order to improve service for its 670,000 daily passengers. The ILOG-powered system has delivered efficiency and productivity improvements which have improved on-time performance to more than 95 percent for the TIBS fleet, which comprises 800 buses that cover more than 72 routes throughout Singapore. TIBS is a wholly owned subsidiary of SMRT Corp, Singapore’s largest public transport company and the first operational multi-modal transportation company.

ILOG’s business rule management system (BRMS), optimization and visualization software components were combined to create an integrated solution that performs bus and personnel dispatching as well as scheduling functions. Deployed as part of TIBS Depot Dispatching System (DDS) and Interchange Dispatching System (IDS), TIBS operators utilize ILOG Views™ to create an interactive display that allows them to visually track fleet movements, ILOG Solver ™ software to create optimized schedules, and ILOG BRMS to automate schedule dispatching. Prior to the ILOG deployment, TIBS used a combination of manual and automated systems to manage operations, a method which did not maximize personnel productivity and deliver the desired level of customer service.

In addition to efficiency gains, ILOG technology has enabled TIBS to be more agile and react quickly to unforeseen circumstances, such as the replacement of drivers and buses in the event of breakdowns, accidents, weather conditions, or sick leaves. ILOG software, installed last year throughout the transportation agency’s network of 20 interchanges and terminals and 4 depots, enables the company to better plan for, react to and manage contingencies by automating business processes involved in the operation of the fleet. The new fully automated system, part of TIBS’ information technology upgrade program, also frees TIBS dispatchers to focus on other operational duties and issues.

“Managing emergency and contingency planning at the depots and interchanges is only one aspect of the daily operations work scope,” said Cheng Jew Hi, Head (Dispatching System), TIBS Head of System Department. “Ensuring timely and smooth operations requires accurate monitoring and the ability to solve problems quickly. ILOG software provides enhanced decision-making capabilities and generates optimized staff schedules, enabling us to provide better service to our customers by ensuring more smooth operations.”

TIBS’ unique operational constraints included maintaining existing processes for procedural changes for reporting and scheduling of bus drivers and depot personnel. ILOG worked with the existing procedures and built an intelligent system that addressed these constraints, while accommodating real time changes to schedules and timetables.

“ILOG software components provide the flexibility and the scalability necessary to meet TIBS’ unique requirements,” said Foo Jong Tong, general manager, ILOG Singapore. “This enables IDS to be an interactive and intuitive application that eases strains on the decision-making process, enabling operators to make the optimum choices based on available resources.
