As the environmental improvement of an operating supply chain implies not only technology upgrading decisions, but also decisions regarding the structure of the supply chain itselfdeciding on what strategy to follow is a complex task. The aim of this work is to provide a bi-objective solution approach for finding such strategy so that both the environmental and financial goals are best met.engInstitute of Industrial EngineersConference PaperEngineersEnvironmental managementEnvironmental technologyEvolutionary algorithmsMultiobjective optimizationSupply chainsSustainable developmentBi objectivesComplex taskEnvironmental improvementsEnvironmental performanceFinancial goalsMulti-objective evolutionarySolution approachSupply chain designEnvironmental impact2021-04-12Ozden S.G.Vélez-Gallego M.C.
