A stochastic Fermatean fuzzy-based multi-choice conic goal programming approach for sustainable supply chain management in end-of-life buildings

Due to natural disasters, urban transformations and many other factors, sustainable end-of-life buildings (ELBs) waste management is gaining importance within the last decades, which is vigorous for both economic and conservation matters. Turkey is located on active zones in terms of natural disasters and faced numerous destructive events. Therefore, the government initiated a program to renew the ELBs. Even though several studies analyzed post-disaster debris management, there are not many studies focusing on pre-disaster debris management. Thus, this study proposes a two-stage stochastic model to optimize the supply chain network of ELBs and manage the debris stemmed from the destruction of the ELBs. With this aim, the criteria and the alternatives for evaluating the objectives are defined, experts’ evaluations for objectives are integrated into the model, Fermatean fuzzy-based weighting approach is introduced to transfer the experts’ views on the importance of the objectives, and the stochastic Fermatean fuzzy-based multi-choice conic goal programming (FF-MCCGP) and the revised-MCGP methods are used to provide optimal facility locations, and the amount of debris to transfer within the network. The stochastic FF-MCCGP approach outperforms the revised-MCGP in most cases, where they are compared. Furthermore, a sustainable management strategy is offered to control the economic, pollution, land-use stress and population health factors. This study is one of the pioneer studies that eases the consequences of diseases, urban transformation, wars, and other factors by considering the renewal of ELBs, and method can be upgraded dynamically regarding the potential needs and conditions as it offers a global road map. •As a sustainable supply chain, the management of end-of-life-building is analyzed.•Locations of recycling and land-filling areas are optimized under uncertainty.•The Fermatean fuzzy-based approach provides the importance of objective functions.•As solution approach a revised multi-choice conic goal programming is proposed.•Strategical road map to authorities in managing pre-disaster debris is constructed.
