A DSS Reshapes the Railway in the Netherlands More than 5,000 trains pass through 2,800 railway kilometers and 400 stations each day in the Netherlands. As of the mid-1990s, the railway infrastructure was hardly sufficient to handle the passenger flow. The problem gets worse during rush hours, and trains are delayed. Passengers complain and tend to use cars, whose variable cost is lower than that of using the train. This increases the congestion on the roads, adding pollution and traffic accidents.

»A DSS Reshapes the Railway in the Netherlands More than 5,000 trains pass through 2,800 railway kilometers and 400 stations each day in the Netherlands. As of the mid-1990s, the railway infrastructure was hardly sufficient to handle the passenger flow. The problem gets worse during rush hours, and trains are delayed. Passengers complain and tend to use cars, whose variable cost is lower than that of using the train. This increases the congestion on the roads, adding pollution and traffic accidents. The largest railway company, Nederlandse Spoorwegen Rail 21 is the name of the government project that aims to bring the system into the twenty first century.It is a complex, multibillion-dollar project. The Government wants to reduce road traffic among the large cities, stimulate regional economies by providing them with a better public transportation system, stimulate rail cargo, and reduce the number of short-distance passenger flights in Europe. NS wants to improve service and profitability. A company called Railned is managing the project, which is scheduled for completion in 2010. Railned developed several alternative infrastructures: PROLOP: This DSS was designed to do the lines optimisation. It involves a database and three quantitative models. It supports several decisions regarding rails, and it can be used to simulate the scenarios of the ?coctails?. It incorporates a management science model, called integer linear programming. PROLOP also compares line systems based on different criteria. Once the appropriate line system is completed, an analysis of the required infrastructure is done, using the second DSS, called DONS. DONS: This DSS is doing capacity checks, i.e., the feasibility of the desired lines systems. It contains a DSS database, graphical user interface, and two algorithmic modules. The first algorithm computes the arrival and departure times for each train at each station where it stops, based on ?hard? constraints STATIONS: Now it is time to route the trains through the railway stations. This is an extremely difficult problem that cannot be solved simultaneously with the timetable. Thus, STATIONS, another DSS, is used. Again, feasible optimal solutions are searched for. If these do not exist, system modifications are made. The DSS solution is fairly complex due to conflicting objectives of the government and the railway company BACHELOR OF COMMERCE YEAR 2 – ACADEMIC AND ASSESSMENT CALENDAR – DISTANCE REGENT BUSINESS SCHOOL (RBS) – January 2019 15 The DSSs were found to be extremely useful. They reduced the planning time and the cost of the analysis and increased the quality of the decisions. An example was an overpass that required an investment of $15 million. DONS came up with a timetable that required an investment of only $7.5 million using an alternative safety arrangement. The DSS solution is used during the operation of the system as well for monitoring and making adjustments and improvements in the system. Using relevant research discuss the concept of a data driven DSS in relation to its usefulness to the railway company.
