The Analytic Hierarchy Process (AHP) is one of the most popular methods used in Multi-Attribute Decision Making. The Eigenvector Method (EM) and some distance minimizing methods such as the Least Squares Method (LSM) are of the possible tools for computing the priorities of the alternatives. A method for generating all the solutions of the LSM problem for 3 × 3 and 4 × 4 matrices is discussed in the paper. Our algorithms are based on the theory of resultants.

A fenntarthatóság értékelése definíciószerűen többdimenziós probléma. A megfelelő alternatíva, forgatókönyv, eljárás stb. kiválasztásakor ugyanis a döntéshozóknak egyszerre kell figyelembe venniük környezetvédelmi, gazdasági és társadalmi szempontokat. Az ilyen döntéseket alátámaszthatják a több szempontú döntéshozatali modellek. A tanulmány a több szempontú döntési eljárások közül a legfontosabb hétnek az alkalmazhatóságát vizsgálja részvételi körülmények között. Az utóbbi évek e témában publikált esettanulmányainak áttekintésével megállapítható, hogy egyik módszer sem uralja a többit, azok különböző feltételek mellett eltérő sikerrel használhatók. Ennek ellenére a különböző módszerek kombinációjával végrehajthatunk olyan eljárásokat, amelyekkel az egyes módszerek előnyeit még jobban kiaknázhatjuk. ________ Measuring and comparing the sustainability of certain actions, scenarios, technologies, etc. is by definition a multidimensional problem. Decision-makers must consider environmental, economic and social aspects when choosing an alternative course of action. Such decisions can be aided by multi-criteria decision analysis (MCDA). This paper investigates seven different MCDA methodologies: MAU, the Analytic Hierarchic Process (AHP), the ELECTRE, PROMETHEE, REGIME, and NAIADE methods, and "Ideal and reference point" approaches). It is based on a series of reports in which over 30 real-world case studies focusing on participatory MCDA were reviewed. It is stressed, however, that there is no "best" choice in the list of MCDA techniques. Some methods fit certain decision problems better than others. Nonetheless, some complementary benefits of the different techniques can be exploited by combining these methodologies.

In the successful strategic management of the modern companies each function plays their specific role. While today’s businesses in many ways are different from their ancestors, the key fundamentals are derived from the same roots. Their main purpose of existence is to serve the needs of their shareholders and stakeholders by creating value (Pike et al., 1993). To achieve this effectively and efficiently the various functions need to work in close cooperation with each other. The global crisis, starting in 2008, proved that volatility is higher for the financial markets and the ordinary businesses that have been anticipated before. As the recession started as a financial crisis many people started to blame – amongst others – banks and financial institutions for excessive risk taking and taking short profits ahead of long term sustainable growth. Accordingly the lost confidence in the financial institutions has taken a toll on the reputation of other Finance professionals such as accountants, book keepers, treasury, tax people and others. The finance function’s strategic importance is linked to its ability to help interpreting the business performance and provide transparency. In order to restore the trust the finance profession is now facing one of the biggest challenges of its history, the need to reinvent itself. This paper presents the findings of a recent international research conducted in the United Kingdom, France, Hungary and Poland interviewing 169 executives of the business sector plus the review of 237 job descriptions of finance professionals in order to understand the challenges of the modern finance function. The findings of the study could provide relevant answers and help to overcome a very current problem that Finance is facing today, how to rebuild reputation and to stay a trusted partner and enabler for long term business strategy.
