Reorganization is one of the key issues of organization theories. The purpose of this paper is to present a graph transformation based meta-model for describing specific structural evolution in multi-agent systems from the view of organizational structures. This meta-model captures our understanding of organizational structures and our considerations of the formal process of dynamic reorganization in open multi-agent environments. In order to express main elements and their inter-relations in the organizational structures, a multi-level graph is proposed as the core concept of the meta-model. Based on the meta-model, an adaptive architecture is also introduced to specify the process of structural evolution of organizations in multi-agent systems and the operational semantics of this reorganization process is defined with algebraic graph transformation. Finally, simulation results are specified with this meta-model

It is important to design an agent with logical and decisive rationality in agent organization. Study about organization focuses on the definition of agent organization model and the analysis of organization formation and evolution, an attractive and challenging issue is how to combine logical and decisive rationality into a uniform framework. This paper aims at arguing the combination with logic and decision in agent organization. To pursue this aim, we extend the notions of commitment and obligation with utility in agent organization and utility reflects agent decision. In order to systematize the notions, formal tools are introduced to describe them as well as the semantics of utility for commitment and obligation are defined. We specify the properties and consequences of the extension for agent organization
