An Optimization Framework for Automated and Human-Operated Fleet Routing

Abstract This paper presents a mathematical model to determine the optimal routes for a heterogeneous fleet comprising autonomous and human-driven vehicles operating in freight distribution. The model is formulated as a mixed-integer programming problem with multiple objectives:...

Pricing semi-cooperation in unstable linear–linear bilevel programs via strictly convex tie-breaking and stability contracts

Abstract When the follower problem in a bilevel program admits multiple optimal solutions, the leader’s outcome depends on how ties are resolved. This yields the classical optimistic/pessimistic ambiguity and makes the model unstable (ill-posed) from a predictive viewpoint. We st...
