Abstract: DEMATEL approach based on cloud model is proposed for the information where attribute weights is totally unknown in multi-attribute decision making. According to system thinking, this method gives sufficient consideration to the complex correlation of attribute weights, and converts experts’ natural language preference to quantify preference by the cloud model. Then it solves the attribute weights with DEMATEL method. This approach is more effective not only on the decisions made by experts under complicated circumstances, but also improves the calculation of attribute weights more scientific and objective. A numerical case shows that the approach is validated to be scientific and it can be well applied to solve the real issues.
