the comprehensive assessment model considers the financial and non-financial aspects as balanced scorecard. also, for more comprehensive results of the investigation, four aspects of the balanced scorecard were used and then by using fuzzy delphi technique and experts' opinions, the standard aspects of each were achieved in two stages. to determine the importance of each aspect of bsc, the proce...

data obtained in association with many real-life random experiments from different fields cannot be perfectly/exactly quantified.hspace{.1cm}often the underlying imprecision can be suitably described in terms of fuzzy numbers/values. for these random experiments, the scale of fuzzy numbers/values enables to capture more variability and subjectivity than that of categorical data, and more accura...

In this paper, we construct two fuzzy sets using the notions of level subsets and strong level subsets of a given fuzzy set in a ring R. These fuzzy sets turn out to be identical and provide a universal construction of a fuzzy ideal generated by a given fuzzy set in a ring. Using this construction and employing the technique of strong level subsets, we provide the shortest and direct fuzzy set ...
