A Hybrid E-institution Model: From the Static to the Dynamic

The formation and operation of the virtual organizations (VO) is to to facilitate resource sharing and problem solving among software and/or human agents. However, due to the selfishness and autonomy of agents, VOs are confronted with the credibility crisis. E-institutions are perfect means to solve the problems of VO credibility crisis. But how E-institutions facilitate the VO in different stages and what is the E-institutions architecture is still blurred. In this paper, we propose a dynamic hybrid E-institution model to provide assistance to the agent interactions. First, the E-institutions are modelled using static elements to make the agent cooperation trustable and predictable; second, the E-institutions are ash modelled using dynamic elements, instantiated information; third, the E-institutions are modelled using conditions under which the static elements are translated into instantiated (dynamic) ones. Different conditions serve different E-institution goals and thus make the E-institution dynamic. This paper presents explicitly formal descriptions of the static organization structure, dynamic information and institutional services to different VO stages.
