Abstract:V diplomskem delu smo razvili spletni informacijski sistem, ki uporabniku pomaga izbrati najboljšo alternativo (rešitev) večkriterijskega odločitvenega problema. Sistem razvrsti (rangira) alternative v več skupin, od najboljše skupine do najslabše. Znotraj posamezne skupine so vse alternative enakovredne. Uporabnikova naloga je le, da glede na lastne izkušnje in dane okoliščine, izbere najbolj ugodno alternativo v najboljši skupini. Sistem je univerzalen, zato omogoča reševanje raznovrstnih odločitvenih problemov. Za razvrstitev (rangiranje) alternativ po prednostnem vrstnem redu smo uporabili modul za nedominirano razvrščanje, ki temelji na Pareto optimalnosti in je napisan v programskem jeziku lisp. Preostali moduli sistema so napisani v javi in z njim komunicirajo prek datotek oblike LSP in XML. Spletna podpora je izvedena s sodobnimi tehnologijami, med katerimi so EJB, JSF, PrimeFaces, jQuery, JavaScript, AJAX, XHTML in CSS3. Delovanje sistema z uporabnikovega zornega kota smo ilustrirali z dvema primeroma. Prvi prikazuje splošni izbor optimalnih alternativ, ko uporabnik poda število alternativ in kriterijev ter obseg vrednosti za vsak kriterij, vrednosti kriterijev za vsako alternativo pa se generirajo naključno, drugi pa izbiro optimalnega dobavitelja z ozirom na ceno, kakovost in dobavni rok izdelka ter renome in oddaljenost dobavitelja.

Title:DEVELOPMENT OF A DECISION SUPPORT SYSTEM USING THE NON-DOMINATED SORTING
Abstract:In this diploma work, we have developed a web-based information system that helps a user to choose the best alternative (solution) regarding a multicriteria decision problem. This system sorts (ranks) alternatives into several groups, from the best to the worst group. All alternatives within each group are equivalent. According to the user’s experiences and the circumstances, his/her task is just to choose the most favourable alternative within the best group. This system is universal and thus allows the solving of a wide range of decision problems. We have used a module for non-dominated sorting based on Pareto optimality and written in Lisp programming language for sorting (ranking) alternatives in the preferred order. The remaining modules of the system are written in Java and communicate with it through the files of types LSP and XML, respectively. Web support is implemented using modern technologies including EJB, JSF, PrimeFaces, jQuery, JavaScript, AJAX, XHTML, and CSS3. Operation of the system from the user's perspective is illustrated using two examples. The first one shows the general selection of optimal alternatives when the user specifies the number of alternatives, the number of criteria, and the range of values for each criterion, whilst the criteria values for each alternative are generated randomly. The second one presents the choice of optimal supplier with respect to price, quality, and delivery time of the product, as well as of the reputation and remoteness of the supplier.
Keywords:decision support systems, ordered set theory, non-dominated sorting, Pareto optimality
