Abstract: A three-echelon supply chain network design and integrated optimization was researched in centralized and decentralized decision model.To reflect the preference and cooperative behavior for decision-makers,the fuzzy multi-objective programming approach was proposed by considering three kinds of fuzzy operator.The influence of three fuzzy operators on system objectives membership degree,function value and supply chain network configuration was investigated.The results indicated that weighted “max-min” operator might represent the key decision-makers preference for goals in centralized decision model and “fuzzy and” operator could reflect member firms cooperative willingness for objectives coordination in decentralized decision model.To balance desired values and assign different weights for multiple objectives,the modified “fuzzy and” operator was put forward by integrating aforementioned two operators advantages.The modified “fuzzy and” operator reflected management thought of centralized decision-making and group negotiation,and could improve decision-making efficiency better.

Key words: supply chain network design, integrated optimization, decision preference, cooperative willingness
