Railway Applications Section

Problem Repository

Problem Repository

This effort is targeted at increasing awareness about difficult railroad problems for the OR community, so that railroad industry can benefit from increased research activity. Complete details of the repository, processes and first problem were presented at the RAS business meeting in Charlotte in 2011.

The objective of this problem repository is to facilitate a platform where:

  1. Reallife railroad application problems are presented along with dataset(s) and solutions publicly available for anyone to research, develop and test solution approaches.
  2. Researchers may showcase their results, engage in questions, answers and discussions and measure the performance of different solution approaches.

All information that is available on RAS website is public. Neither RAS, nor the company/entity (who provided the problem/data to the repository) may claim intellectual property rights on the outcome of the research by someone who used the data/problem description. RAS is open to suggestions - please contact any of the officers if you have any suggestions or start a discussion on our LinkedIn page.
