Train Travel-Time Estimation
The world is experiencing phenomenal advancements in the accuracy of travel time estimations in over-the-road and air travel modes. Many of these advancements are widely available and can predict the estimated arrival time at the destination as well as intermediate stations with a high degree of accuracy. However, the accuracy of travel-time estimations lags far behind for rail transportation, especially in freight transportation by rail.
For this year’s competition, participants will be asked to determine the travel time of freight trains within a given time window, considering all important characteristics of the network and important resources required for freight train operations. Rail transportation is one of the most efficient and the most environmentally friendly modes of transportation on a per ton-mile basis because of the dedicated trackage for train movements. However, this characteristic also creates inherent cascading impact of each train’s movements on the movement of other trains in the network. Combining this complex interdependency with other resource-specific restrictions makes the train travel-time estimation problem an algorithmically challenging problem. Solving this challenging problem effectively will not only have immediate benefits to freight railroads and their customers but will also enable other important decision problems affecting railroad operations to be addressed.
A preliminary problem description can be found in the link above. A full description of the problem under consideration, as well as complete data files for the competition problems will be available by April 3, 2020.
The criteria that judges will use to evaluate a solution include the following:
(The attendance and presentation of at least one person from each finalist team is required)
The finalists will make a presentation at the 2020 INFORMS Annual Meeting. Aside from the previous factors, the judging panel will take into consideration the clarity of the presentation to make a final decision about the first, second and third places for the competition. Note that being among the finalists and presenting at the Annual Meeting does not guarantee a finalist will receive first, second or third place. The decision of the judges is final.
In addition to the cash prizes, the first prize winners’ contribution to this competition will also be considered for publication in the journal Networks. The paper still needs to go through the journal’s refereeing process, however, it will receive an expedited refereeing and publication process.
Any practitioners of operations research and management science who are interested in solving problems in the railroad domain using Operations Research and Analytics tools are welcome to participate. Registration is open to all with the exception of RAS officers and organizing committee members. Likewise, members of the organizing committee may NOT help nor guide any participating team.
Teams of up to three members can participate. At least one member of each finalist team must be available to present the team’s approach and results at the 2020 INFORMS Annual Meeting.
Participation in the RAS Problem Solving Competition requires registration by May 22, 2020. Every team must register by the due date to participate in the contest. To register, please send the following information to [email protected] by the deadline.
After submitting your registration email, you will receive an email confirming your team’s successful registration and eligibility.
Can I publish?
Yes, you can. In fact, RAS encourages you to do so. Anyone can use the RAS competition problem and provided datasets in their publication. References to year-specific problem competitions are given in the URL, and as such you can reference the year-specific competition URL which will not be changed.
Watch for the full problem description on April 17, 2020!
Good luck in the competition!
