This presentation is based on paper that includes coauthors Guy De Tré, Navchetan Singh, Daniel Tomasevich and Ryoichi Yokoohji. We present a decision support system that uses soft computing models for evaluation, selection and pricing of homes. The system (called LSPhome) is based on the Logic Scoring of Preference (LSP) evaluation method and implemented in the context of online real estate. The goal of this system is to use weighted compensative logic models that can precisely express user needs, and help both buyers and sellers of homes. The design of such a system creates specific logic and computational challenges. Soft computing logic problems include the use of verbalized importance scales for derivation of andness, penalty-controlled missingness-tolerant logic aggregation, detailed and verbalized presentation of evaluation results, and development of optimum pricing models. Computational problems include fast and parallel collection of heterogeneous information from the Internet, and development of user interface for fast and simple creation of customized soft computing decision criteria by nonprofessional decision makers.


Jozo Dujmović was born in Dubrovnik, Croatia, and received the Dipl. Ing. degree in electronic and telecommunication engineering in 1964, and the M.Sc. and Sc.D. degrees in computer engineering, in 1973 and 1976 respectively, all from the University of Belgrade, Serbia.
Since 1994 he has been Professor of Computer Science at San Francisco State University, where he served as Chair of Computer Science Department from 1998 to 2002. His teaching and research activities are in the areas of soft computing, software metrics and computer performance evaluation. He is the author of 150 refereed publications, including 14 books and book chapters. Before his current position at San Francisco State University, he was Professor of Computer Science at the University of Belgrade, University of Florida (Gainesville), University of Texas (Dallas), and Worcester Polytechnic Institute. In addition, he was teaching in the graduate Computer Science programs at the National Universities of San Luis and Jujuy (both in Argentina). At the University of Belgrade, where he was teaching from 1968 to 1992, he also served as Chairman of Computer Science Department, and as founding Director of the Belgrade University Computing Center.
