Formalizing Interactive Institution with RBA Calculus

摘要

Although organization oriented paradigm is a promising way to design dynamic interactive computational systems in open and heterogeneous networked environment, there is still lack of a suitable formal approach to support this paradigm. RBA, a boxed ambient calculus extended with separated regulating mechanism, is proposed to design such systems. In RBA, an ambient is an encapsulating mobile unit parameterized with role-governors that regulating actions of the corresponding role-players participating into this ambient. Firstly the formal syntax and semantics of RBA are given. Secondly an electronic institution model is applied to illustrate the RBA approach. Based on the bisimulation theory of process calculi, verification and validation of design specifications are supported with RBA approach.
