We consider a hub and spoke location problem (HSLP) with multiple scenarios. The HSLP consists of four sub-problems: hub location, spoke location, spoke allocation, and customer allocation. Under multiple scenarios, we aim to provide a set of well-distributed solutions, close to the true Pareto optimal solutions, for decision makers. We present a novel multi-objective symbiotic evolutionary algorithm to solve the HSLP under multiple scenarios. The algorithm is modeled as a two-leveled structure, which we call the two-leveled multi-objective symbiotic evolutionary algorithm (TMSEA). In TMSEA, two main processes imitating symbiotic evolution and endosymbiotic evolution are ...
