I have been looking to solve a train scheduling problem using bilevel optimization.
In this problem, two conflicting objectives are considered: the operator’s and the passengers’, having the passengers’ optimization problem nested inside the operator’s optimization problem (as a constraint). Is it possible to model this type of bilevel optimization problem? If not, are there other approaches using stackelberg games that can be considered?
Thank you very much.
Were you able to try Mohan’s suggestion of modeling it as a multi-objective problem?
