The lack of support for contradictions in fsQCA limits the method’s usefulness for conducting inductive research. In this paper, I describe how to extend fsQCA to accommodate contradictory conditions.

This paper seeks to provide the services sector with a focus on the assessment of quality and for this purpose, a technique that may able a quantitative approach to evaluating quality is proposed. The use of the fuzzy sets theory to process data was used, thus allowing a more flexible and...

In this paper statistical tests with fuzzily formulated hypotheses are discussed, i.e., hypotheses H <Subscript>0</Subscript> and H <Subscript>1</Subscript> are fuzzy sets. The classical criteria of the errors of type I and type II are generalized, and this approach is applied to the linear hypothesis in the linear regression model. A...</subscript></subscript>

The importance of the historical information in flood analysis has previously been underlined. In this context, we present an integral methodology aimed at the establishment of return periods of different flood units on the unique basis of historical data. Specifically, the reconstruction of the...

The goal of a water distribution system (WDS) is to deliver safe water with desirable quality, quantity and continuity to the consumers. In some cases, a WDS fails to deliver safe water due to the compromise/ failure of water quality which may have devastating consequences. The frequency and...

Improper agricultural practices can affect ground water through leaching, surface water through runoff, algae infestations, deforestation, and air quality through burning operations and ammonia emissions. These effects may be mitigated through the institution of best management practices. The...

Water resources management can be regarded as an iterative process of general decision making considering the applications and modifications of waters and related lands within a geographic region. This process helps decision makers to balance their diverse requirements and applications of water...

There are several divisions of countries and regions in the world. Besides geo-political divisions, there also are economic divisions. The most common economic division is the that on developed countries and the poor ones. These divisions are a consequence of the level of: GDP, GDP per capita,...

An indicator that measures the compliance with the constitutional principles of a plural economy is proposed. An inference system based on fuzzy sets was used to calculate the indicator. The fuzzy system summarizes the principles of income redistribution and environmental sustainability into an...
