We have developed a non-linear multi-objective model for optimal design of railway timetables. The objectives of the model are to maximize schedule reliability and minimize energy consumption, rolling stock and crew deployment. Metrics have been derived for each of these objectives. AHP is used...

Real-life problems are complex because they are typically made up of several sub-problems interacting. These interactions establish an interdependent relationship in which the quality of one partial solution impacts the quality of other partial solutions. Recently, a new benchmark known as the...
