A better score function for multiple criteria decision making in fuzzy environment with criteria choice under risk

作者：

Highlights：

• A multiple criteria decision making problem under risk is considered.

• A new score function and a new weighted geometric aggregation operator are defined.

• Some theoretical properties of the score function and operator are established.

• A new method for ranking the alternatives is developed.

• An algorithm for ranking is presented and its working illustrated by an example.
