This paper makes an extension of Strength Pareto Evolutionary Algorithm 2 - SPEA2 - and Multi-objective Particle Swarm Optimization - MOPSO -, which ones are traditionally used in multi-objective optimization, these are modified to the case of multi-objective uncertain optimization, where the model uses the interval-valued optimization as shown by Wu [?, ?, ?], these new algorithms have arithmetic advantage in the image set of the objective function. At the end, numerical examples are shown where they applied the algorithms implemented.engworkingPaperinfo:eu-repo/semantics/restrictedAccessAcceso restringido2014-12-11Puerta Yepes, María EugeniaCano Cadavid, Andrés Felipe
