Green supplier selection in the ready mixed concrete industry with VIKOR and PROMETHEE II based on diffrent weighting methods

Today, the competitive environment faced by businesses is quite strong. The decrease in natural resources used, environmental pollution and imbalances in ecology cause climate changes, and the livable environment is increasingly limited. Businesses should attach importance to sustainable production in order to increase their competitiveness in the market in which they do business, and work to reduce the damage they cause to the environment. In this study, the suppliers of a business operating in the ready mixed concrete sector were evaluated. In the study, cost, quality, green product, green image, environmental criteria and delivery criteria were used as the main criteria. While choosing the supplier, weighting was done with entropy and critic methods, and supplier selection was made with vikor and promethee II methods.
