The Second Life game was published in 2003 by Linden Lab and it is a representative of MMORPG games, in which many people can play with each other. The slogan of game is: Your World. Your Imagination. Player who came into Second Life world impersonate virtual person and leads all its actions. Virtual person can be different than player is. Very often virtual persons are created to be like dreams. World programmed as place where people can freely realize own needs, where everyone is happy, displays a lot of interesting features, becomes a "first draft", is susceptible to changes. This world become a place where companies earn, where politicians presents theirs ideology and where social experiments are performed. In the level of individual is the place where players can experiment with theirs owns identity.

Zaprezentowano wprowadzenie do wielokryterialnego podejmowania decyzji z użyciem dwóch decyzyjnych narzędzi: Analitycznego Procesu Hierarchicznego (AHP) oraz jego udoskonalonej formy - Analitycznego Procesu Sieciowego (ANP). Przedstawiono teoretyczny aspekt obu metod oraz przykłady ich praktycznego wykorzystania do rozwiązania niektórych z otaczających nas problemów. Metoda ANP została zaprezentowana po raz pierwszy w Polsce i wykorzystana w rozwiązywaniu praktycznego problemu poprawy jakości produktów żywnościowych.

This article presents an introduction to multicriteria decision making using two decision tools: the j Analytic Hierarchy Process (AHP) and its generalization to dependence and feedback - the Analytic j Network Process (ANP). The discussion involves theoretical aspects of these methods and some exam- J pies of their applications, (e.g. the first application of the ANP, in improving of food ąuality products, in l Poland), in organizational and management problems solving. AHP and ANP introduced by ThoroasJ L. Saaty from the University in Pittsburgh, USA. The Analytic Hierarchy Process has been one of t fastest developing mathematical methods over the recent years used for solving multi-criteria decisio problems. The AHP is a generał theory of measurement based on some mathematical and psychologia principles. In that method a hierarchie decision scheme is constructed, by the breaking the problem inl decision elements: goal, criteria, subcriteria, sub-subcriteria (...) and decision alternatives. The goal is o the top of hierarchy, whereas altematives create the lowest level of hierarchy. The imponance of t decision element is established, through the pair-wise comparison of elements on each level of the hie chic structure, with regard to elements on the level above. To do the comparisons it is using the Są fundamental scalę for paired comparisons for the analysis of both quantitative and qualitative varia The Analytic Network Process (ANP) is a new theory that extends the Analytic Hierarchy Process (AH The basie structures arę networks, which allow interactions and feedback within the cluslers and betw the clusters. So, it can be applied for soMng morę sophisticated decision problems. Authors' intention was to showing utility of these methods, which can be successfully applied in i solution of any multicriteria enterprise.
