Bilevel optimization is defined as a mathematical program, where an optimization problem
contains another optimization problem as a constraint. These problems have received …

Bilevel optimization problems are hierarchical optimization problems where the feasible
region of the so-called upper level problem is restricted by the graph of the solution set …

While Stackelberg leader–follower games and bilevel programming have become
increasingly prevalent in game-theoretic modeling and optimization of decentralized supply …

Many practical multiobjective optimization problems have a nested bilevel structure in
variables, which can be modeled as bilevel multiobjective optimization problems (BLMOPs) …

This paper studies a discontinuous lane reservation problem considering the
heterogeneous traffic demand containing both vehicles with general purposes and vehicles …

Optimization problems involving two decision makers at two different decision levels are
referred to as bi-level programming problems. In this work, we present novel algorithms for …

This paper addresses a generalized version of the facility location problem with customer
preferences which includes an additional constraint on the number of customers which can …

Bilevel integer linear programming (BILP) problems have been studied for decades. Many
exact algorithms have been proposed in recent years for small-or medium-sized instances …

This paper presents a bilevel capacitated facility location problem where customers are
allocated to the facilities they patronize based on a predetermined list of preferences. The …

We consider facility location problems with a new form of equity criterion. Demand points
have preference order on the sites where the plants can be located. The goal is to find the …
