This study examines the notion of inconsistency in pairwise comparisons for providing an axiomatization it. It also proposes two indicators comparisons. The primary motivation reduction is expresse
We forecast 1,000,000 COVID-19 cases outside of China by March 31st, 2020 based on a heuristic and WHO situation reports. do not model the pandemic; we only number cases. The proposed is simple observation that plot given data well approximated an exponential curve. curve used for forecasting growth new It has been tested last report day. Its accuracy 1.29% day added predicted 57 previous reports (the date 18 2020). Prediction, forecast, pandemic, COVID-19, coronavirus, parameter, heuristic,...
This study has been inspired by numerous requests for clarification from researchers who often confuse Saaty's Analytic Hierarchy Process (AHP) with the pairwise comparisons (PC) method, taking AHP as only representation of PC. should be regarded an interpretation and clarificatio n past investigations In addition, this article is a reflection on general PC research at higher level abstraction: philosophy science. It delves into foundations implications comparisons. Some results are based...
Symmetry and antisymmetry are fundamental concepts in many strict sciences. Pairwise comparisons (PC) matrices tools for representing pairwise relations decision making. In this theoretical study, we present a novel framework that embeds additive skew-symmetric PC into the Grassmannian manifold $G(2, n)$. This leverages Pl\"ucker coordinates to provide rigorous geometric interpretation of their structure. Our key result demonstrates algebraic consistency condition $a_{ij} + a_{jk} - a_{ki} =...

Comparison, rating, and ranking of alternative solutions, in case multicriteria evaluations, have been an eternal focus operations research optimization theory. There exist numerous approaches at practical solving the problem. The recent interest this domain was event parametric evaluation entities Poland. principal methodology based on pairwise comparisons. For each single comparison, four criteria used. One controversial points assumed approach that weights these were arbitrary. main study...
Rating scales are used to elicit data about qualitative entities (e.g., research collaboration). This study presents an innovative method for reducing the number of rating scale items without predictability loss. The "area under receiver operator curve method" (AUC ROC) is used. presented has reduced (variables) 28.57% (from 21 6) making over 70% collected unnecessary. Results have been verified by two methods analysis: Graded Response Model (GRM) and Confirmatory Factor Analysis (CFA). GRM...
Abstract This study provides a proof that the limit of distance-based inconsistency reduction process is matrix induced by vector geometric means rows when inconsistent pairwise comparisons transformed into consistent PC stepwise in triads. The indicator was defined Koczkodaj (1993) for comparisons. Its convergence analyzed 1996 (regretfully, with an incomplete proof) and finally completed 2010. However, there no interpretation provided despite its considerable importance. also demonstrates...
A statistical experiment was designed to check whether the pairwise comparisons method, introduced by Thurstone in 1927, can really improve accuracy of estimation stimuli. This method compared with direct rating. The and implemented minimize bias. Randomly generated bars were used since everyone is an expert on estimating lengths. analysis favoured obtained results are decisive; more than a 300% improvement gained at least 10 level confidence.
This study presents theoretical proof and empirical evidence of the reduction algorithm convergence for distance-based inconsistency in pairwise comparisons. Our research shows that very quick. It usually takes less than
