An inconsistency control system based on incomplete pairwise comparison matrices

Incomplete pairwise comparison matrix was introduced by Harker in 1987 for the case in which the decision maker does not fill in the whole matrix completely due to, e.g., time limitations. However, incomplete matrices occur in a natural way even if the decision maker provides a completely filled in matrix in the end. In each step of the total n(n–1)/2, an incomplete pairwise comparison is given, except for the last one where the matrix turns into complete. Recent results on incomplete matrices make it possible to estimate inconsistency indices CR and CM by the computation of tight lower bounds in each step of the filling in process. Additional information on ordinal inconsistency is also provided. Results can be applied in any decision support system based on pairwise comparison matrices. The decision maker gets an immediate feedback in case of mistypes, possibly causing a high level of inconsistency.

Pairwise comparison matrices: an empirical research

Our research focused on testing various characteristics of pairwise comparison (PC) matrices in controlled experiments. About 270 students have been involved in the test exercises and the final pool contained 450 matrices. Our team conducted experiments with matrices of different size obtained from different types of MADM problems. The matrix elements have been generated by different questioning orders, too. The cases have been divided into 18 subgroups according to the key factors to be analyzed. The testing environment made it possible to analyze the dynamics of inconsistency as the number of elements increased in a given case. Various types of inconsistency indices have been applied. The consequent behavior of the decision maker has also been analyzed in case of incomplete matrices using indicators to measure the deviation from the final ranking of alternatives and from the final score vector.

Spirituality and business: An interdisciplinary overview

The paper gives an interdisciplinary overview of the emerging field of spirituality and business. It uses insights from business ethics, theology, neuroscience, psychology, gender studies, and philosophy to economics, management, organizational science, and banking and refers to different religious convictions including Christianity, Judaism, Islam, Hinduism, Buddhism, Confucianism, the Baha'i faith, and the North-American aboriginal worldview. The authors argue that the materialistic management paradigm has failed. They explore new values for post-materialistic management: frugality, deep ecology, trust, reciprocity, responsibility for future generations, and authenticity. Within this framework profit and growth are no longer ultimate aims but elements in a wider set of values. Similarly, cost-benefit calculations are no longer the essence of management but are part of a broader concept of wisdom in leadership. Spirit-driven businesses require intrinsic motivation for serving the common good and using holistic evaluation schemes for measuring success. The Palgrave Handbook of Business and Spirituality, edited by the authors, is a response to developments that simultaneously challenge the “business as usual” mindset.

A méltányosság – egy kísérlet a fogalom tisztázására (The fairness: an attempt to clarify the term)

A méltányosság egyaránt szerepet játszik a társadalmi, szervezeti és szervezetközi kapcsolatokban. A szakirodalom szerint a mindkét fél által méltányosnak tekintett kapcsolatok növelik a részt vevő szervezetek aggregált eredményességét, hosszú távon a kölcsönös és közös versenyelőny kialakítását szolgálják. De mit jelent a méltányosság? A szerző ismerteti a méltányosság és a hozzá szorosan kötődő fogalmak általános meghatározását, majd megvizsgálja Arisztotelész nézeteit az igazságosságról és a méltányosságról. Érint néhány filozófiai koncepciót, melyek a társadalmi igazságosságot egymástól eltérő módon interpretálják, majd részletezi a közgazdaságtan, a kísérleti közgazdaságtan, valamint a szervezeti pszichológia legjelentősebb igazságossági és méltányossági koncepcióit. A tanulmány átfogó képet nyújt a méltányosság definícióiról az áttekintett szakirodalom és a további vállalatközi méltányosságkutatáshoz kötődő relevancia alapján. _______ Fairness plays a role in social,organizational and interorganizational relations. Relationships which are considered to be fair by both parties increase the aggregate effectiveness of the participating organizations and develop mutual and reciprocal competitive advantage in the long-run. But what does fairness mean? The author describes the general definition of fairness and its closely related notions, which is followed by a review of Aristotle’s understanding of justice and equity. Some of the philosophical concepts with different social justice interpretation are examined. The author details the most important concepts of justice, equity and fairness of economics, experimental economics, and organizational psychology. The study provides a comprehensive picture of fairness and equity definitions based on the literature overview and the relevance of further research related to inter-company fairness.
