Relational structures for measures of ignorance

Introducing a Relational Network DEA Model with Stochastic Intermediate measures for Portfolio Optimization

Ignorance in the Relational Model

We hypothesize that an extensionwith-conditioning of Dempster-Shafer theory is suitable for encoding uncertainty and ignorance in the Relational Model. We present a formal and well-motivated definition of conditioning, and show the spirit of the required change in the Relational Model and some results that then follow. It remains to be investigated whether these results are satisfactory.

A Comparative Analysis of Institutional Identities in a Corpus of English and Persian News Interviews

Institutional identity as a concept in CDA is a field of study that deals with the identities that individuals in institutions obtain, one that merits deep research attention. News interviews as institutional instances can be analyzed based on the impersonal structures because interviewees see themselves as part of the institution and they may not take responsibility when they encounter problem...

Revenue - Profit Measurement in Data Envelopment Analysis with Dynamic Network Structures: A Relational Model

The correlated models are introduced in this article regarding revenue efficiency and profit efficiency in dynamic network production systems. The proposed models are not only applicable in measuring efficiency of divisional, periodical and overall efficiencies, but recognizing the exact sources of inefficiency with respect to revenue and profit efficiencies. Two numerical examples, consisting ...

Solving a non-convex non-linear optimization problem constrained by fuzzy relational equations and Sugeno-Weber family of t-norms

Sugeno-Weber family of t-norms and t-conorms is one of the most applied one in various fuzzy modelling problems. This family of t-norms and t-conorms was suggested by Weber for modeling intersection and union of fuzzy sets. Also, the t-conorms were suggested as addition rules by Sugeno for so-called  $lambda$–fuzzy measures. In this paper, we study a nonlinear optimization problem where the fea...
