Abstract :
Computer-supported cooperative work (CSCW) emerged in the middle of the 80s as an identifiable research field focused on the role of computer technology in group work. CSCW examines how people work together in groups and how computer technology can support them. FISM (flexible interpretive structural modeling) developed by the author, is a method to develop structural models of complex systems. In this paper, FISM is extended to develop a new method: FISM/fuzzy. FISM/fuzzy is a fuzzy version of FISM. Some theoretical results which enable us to model logically and efficiently are derived. The process of constructing the structure of complex systems by FISM/fuzzy is called the FISM/fuzzy session. An outline of the FISM/fuzzy session is described and efficiency of the session is given
