Abstract EN
Train scheduling has been a significant issue in the railway industry.
Over the last few years, numerous approaches and tools have been developed to compute railway scheduling.
In this paper, we present a set of heuristics for a constraint-based train scheduling tool, which is a project in collaboration with the National Network of Spanish Railways (RENFE), Spain.
We formulate train scheduling as constraint optimization problems.
Three heuristics are developed to speed up and direct the search toward suboptimal solutions in periodic train scheduling problems.
The feasibility of our problem-oriented heuristics is confirmed with experimentation using real-life data.
The results show that these techniques enable MIP solvers such as LINGO and ILOG Concert Technology (CPLEX) to terminate earlier with good solutions.
