By a News Reporter-Staff News Editor at Computer Weekly News -- Rail transportation is costly to operate and requires heavy fixed-capital investment in track construction and maintenance.
As demand grows, rail system operators can invest in network expansion by building new lines or duplicating existing tracks. However, this strategy is costly because of the long distances traveled by trains. An alternative is to seek solutions that optimize the use of implemented resources by the efficient planning of train overtakings or crossings, stoppage times, track maintenance, and driver rotas.
Most railroads do this planning manually or use traditional mathematical optimization tools. However, rail transport is constantly subjected to a wide variety of unforeseen situations - such as a train breakdown or track interdiction - that can jeopardize the entire system, since operational control involves a large number of interconnected variables. Cases like this are likely to require the restructuring of the entire plan.
“Most tools that use traditional optimization models take hours to calculate a result. CFlex calculates a feasible …
