A conflict measure model and its application to supplier evaluation under environmental uncertainty
As environmental issues are of increased concern, many enterprises have participated in some forms of green-purchasing initiatives. Beside the traditional criteria, the supplier's environmental consciousness, environmental mission, advances in developing environmentally friendly goods, etc., should be evaluated. The attitude difference among supply chain partners will create potential problems for their cooperation and collaboration. A conflict evaluation method is proposed based on measuring their inconsistent attitudes toward important issues such as the environmental ones. A model is built for discovering weight parameters from experience. A pre-qualification process is suggested for screening the suppliers by eliminating those conflicts with the buyer firm.
