Multiobjective network optimization
* Today * Tuesday 08 September 2026, 15:15, M1 (M232)
In multiobjective optimization, several - often conflicting - objective functions are minimized simultaneously. As a consequence, there is generally no single total ordering of the feasible solutions and hence no unique notion of optimality. Instead, the goal is to identify efficient solutions, whose images are the non-dominated points forming the so-called Pareto front. Many network design tasks involve conflicting goals, such as cost, travel time, and demand attraction. Here, we examine two such multiobjective network optimization problems in detail. For both problems, we propose tailored scalarizations that retain problem structure, and analyze complexity and size of the Pareto front. We test the developed algorithms in an extensive computational study, on both generated and real-world data.
