Abstract

Because of the increasing popularity on
protecting the environment, consumers prefer environmentally friendly products
in recent years. Due to the trend between consumers, companies have changed
their production processes. The first necessity for production of an
environmentally friendly product is to supply less harmless raw materials.
Therefore, companies have to supply production inputs from green suppliers in
order to produce environmentally friendly products. Since the wide use range of
textile products make them products that is desired to be green products, green
supplier selection of a textile manufacturer is considered in this study. The
main aim in this study is to propose a decision model for determination of the
best green suppliers. In the proposed model, Analytic Hierarchy Process (AHP)
and Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) methods are
integrated. AHP is used to determine criteria weights and VIKOR is used to
evaluate alternative suppliers. Seven alternative green suppliers are evaluated
by taking 5 main criteria and 17 sub-criteria into account according to the
opinions of planning department experts of the company. Alternative green
suppliers are ranked by using the proposed methodology and the study is
concluded with suggestions for further studies and by giving some managerial
implications.
