Sustainable supplier selection and order lot-sizing: an integrated multi-objective decision-making process by Azadnia, Amir Hossein, Mat Saman, Muhamad Zameri, Wong, Kuan Yew

“…In this research, we propose an integrated approach of rule-based weighted fuzzy method, fuzzy analytical hierarchy process and multi-objective mathematical programming for sustainable supplier selection and order allocation combined with multi-period multi-product lot-sizing problem. The mathematical programming model consists of four objective functions which are minimising total cost, maximising total social score, maximising total environmental score and maximising total economic qualitative score. …”
