This paper considers the International Joint Ventures (IJVs) problem using interval-valued fuzzy sets and the compositional rule of inference in the statistical sense. We consider the performance effects of evaluation criteria facts and weights based on fuzzy set theory to determine the performance ranking among IJVs. Due to the lack of precise information based on some fuzzy language is used in the evaluation criterion. We use the statistical confidence-interval estimates and apply the signed distance method to defuzzify.
