This paper presents an agent based model for analysis of utility conflicts in online communities. Community`s utility, such as collective wisdom for problem solving, is supported by diversity of users regarding knowledge and points of view. On the other hand, community user’s personal utility, such as sense of unity or sympathy, is enhanced by shared values. Therefore online communities sometimes may have uniform or exclusive characteristics when users are pursuing their personal utilities. For these reasons, we assume that underlying conflicts between community’s utility and user’s personal utility exist in online communities. In this paper, some harnessing approaches for mitigating utility conflicts are presented by modeling of community’s and user’s utility functions. Agent based modeling and simulation method is applied in order to observe the emergence process of online community’s characteristics through mutual interaction among users.
