Abstract The current global freshwater crisis threatens the present and future supply of water as a resource for humans. scarcity drinking dependence food industry on water-intensive chains require urgent development strategies to analyze guarantee sustainability countries. This study proposes fuzzy-data envelopment analysis composite index that measures, from benchmarking approach, by simultan...

Multilateral cooperation in higher education among BRICS countries has been under way for 7 years, since 2013. Scholars have different views and judgments, some positive optimistic, negative pessimistic, regarding the significance, progress prospects of (BRICS HEC). What are judgments participants from Chinese universities? This question not yet answered due to a lack relevant empirical researc...

The article discusses the development of social infrastructure agriculture in Chuvash Republic for period from 2009 to 2018. Agriculture occupies a special position region’s economy and is backbone industry. Its share gross regional product 9%, which noticeably higher than other regions country, residents living rural areas 36.6%. With help Excel program, forecast most important indicators 2019...

Variable precision multigranulation fuzzy rough sets (VP-MFRSs) use two direct integrations: the maximum and minimum. Their optimistic pessimistic models facilitate uncertainty informatization but also imply a potential limitation of extremes. This study improves VP-MFRSs for extension balance, thus, decision-theoretic (DT-MFRSs) are proposed by systematically fusing For DT-MFRSs, their tri-lev...

Optimistic methods of concurrency control are gaining popularity. This is especially true with the resurgence of mobile and distributed databases, which inherently rely on optimistic techniques to improve availability and performance of the database system. A key problem with optimistic techniques is that they do not perform well in highly conflict prone environments. Pessimistic techniques, es...

We study the notion of solvability in the resource calculus, an extension of the λ-calculus modelling resource consumption. Since this calculus is non-deterministic, two different notions of solvability arise, one optimistic (angelical, may) and one pessimistic (demoniac, must). We give a syntactical, operational and logical characterization for the may-solvability and only a partial characteri...

In this paper, we have proposed the strategies for concurrency control of global transactions in heterogeneous distributed database systems. We have focused on the issues of consistency, local autonomy and performance. A technique to prevent and resolve inconsistency, classified into one of the two basic approaches: optimistic or pessimistic. The previous research intends to provide a high degr...

This paper proposes a qualitative approach to solve multicriteria decision making problems under possibilistic uncertainty. Depending on the decision maker attitude with respect to uncertainty (i.e. optimistic or pessimistic) and on her attitude with respect to criteria (i.e. conjunctive or disjunctive), four ex-ante and four ex-post decision rules are defined and investigated. In particular, t...

Goeree & Holt (2001) observe that, for some parameter values, Nash equilibrium provides good predictions for actual behaviour in experiments. For other payoff parameters, however, actual behaviour deviates consistently from that predicted by Nash equilibria. They attribute the robust deviations from Nash equilibrium to actual players' considering not only marginal gains and losses but also tota...
