The rescheduling system for trains, drivers and crew of high speed railways

We are developing the new rescheduling system for drivers and crew that synchronizes the train forecasted plan. The East Japan Railway Company has five Bullet Train lines (SHINKANSEN) operating about 800 trains per day, and dispatching nearly 250 drivers and 350 crew per day in order to operate the trains. To keep the operation plan and management of SHINKANSEN properly, we have the system named COSMOS (Computerized Safety Maintenance and Operation systems of SHINKANSEN). The drivers and crew rostering schedule are made with the drivers and crew rescheduling system that is one of the sub-systems of COSMOS Transportation Planning System. Each driver and crew works on their trains according to a rostering scheduling decided upon beforehand normally. However, sometimes trains would be unable to operate on schedule when the weather is bad or car troubles happen. In such cases, the rostering scheduling must be redesigned. The influence reaches the two or more crews ’ rostering scheduling by changing only one crew member. It is very difficult to make this rescheduling because a delay of the train changes minute by minute. To make the crews ’ rostering scheduling change adequately, we have developed a new system. This system displays some contradictions of the rescheduled plan of drivers and crew if a train delay happened. Dispatchers reschedule the plan to solve these contradictions. We reduce the delay time of trains by utilizing this system and will improve our services for customers
