Journal ArticleDOI
A novel hybrid method using fuzzy decision making and multi-objective programming for sustainable-reliable supplier selection in two-echelon supply chain design
Erfan Babaee Tirkolaee,Abbas Mardani,Zahra Dashtian,Mehdi Soltani,Gerhard-Wilhelm Weber,Gerhard-Wilhelm Weber +5 more
TL;DR: A novel hybrid approach based on the fuzzy logic is implemented to address the sustainable supplier selection problem and Weighted Goal Programming (WGP) method is used to deal with multi-objectiveness.
Journal ArticleDOI
Sustainable fuzzy multi-trip location-routing problem for medical waste management during the COVID-19 outbreak.
TL;DR: A novel mixed-integer linear programming (MILP) model is developed to formulate the sustainable multi-trip location-routing problem with time windows (MTLRP-TW) for medical waste management in the COVID-19 pandemic.
Journal ArticleDOI
CMARS: a new contribution to nonparametric regression with multivariate adaptive regression splines supported by continuous optimization
TL;DR: In this article, the authors used a penalized residual sum of squares for MARS as a Tikhonov regularization problem, and treated this with continuous optimization technique, in particular, the framework of conic quadratic programming.
Journal ArticleDOI
A robust green location-allocation-inventory problem to design an urban waste management system under uncertainty.
Erfan Babaee Tirkolaee,Iraj Mahdavi,Mir Mehdi Seyyed Esfahani,Gerhard-Wilhelm Weber,Gerhard-Wilhelm Weber +4 more
TL;DR: A robust green location-allocation-inventory problem (LAIP) is investigated to design an efficient MSW management system and the concept of robustness worthiness threshold (RWT) under budget constraint is introduced and discussed.
Journal ArticleDOI
Fuzzy Mathematical Programming and Self-Adaptive Artificial Fish Swarm Algorithm for Just-in-Time Energy-Aware Flow Shop Scheduling Problem With Outsourcing Option
TL;DR: A novel biobjective mixed-integer linear programming (MILP) model is proposed for FSS with an outsourcing option and just-in-time delivery in order to simultaneously minimize the total cost of the production system and total energy consumption.
