Extended MULTIMOORA method for green supplier selection based on entropy measure for objective weighting

چکیده مقاله

Nowadays with increasing awareness of environmental protection and sustainable green
development in enterprises, the green supplier selection (GSS) in supply chain has become an
important issue for almost every manufacturer in firms. While the works on evaluation and
selection the suppliers are abundant, but the environmental issues are rather limited. In this
study, we examined multi attribute decision making (MADM) problems to determine the green
supplier among the group of suppliers and ranking them with attention to attributes. Also the full
Multiplicative Form added to MOORA (Multi-Objective Optimization by Ratio Analysis) under
the name of MULTIMOORA is developed to solve the case study (laptop manufacturer in
Malaysia). On the other side, we used objective weights based on Shannon entropy for attribute’s
weighting. In the numerical example we have two levels for attributes, the main attribute and sub
attribute that weight them by using of AHP weighting method. The final results show the average
rank of alternatives from Ratio System, Reference Point and Full Multiplicative Form.
