This paper considers the formal analysis and verification methods for the environmental resource adaptability of component-based Interneware. Firstly, the resource interface automata is used to model the behaviors of component interfaces which contain the information of dynamical resource utilization, and the resource interface automaton networks are constructed to describe the compositional behaviors of the system. At the same time, the UML sequence diagrams are used to model the specifications of specified behaviors in the compositional system. Then, two typical problems are proposed and analyzed formally, one of them is to check whether all behaviors of a system are satisfied within the specified resource constraints, and the other is the verification of whether the specified behaviors are satisfied when the resources have been changed. Based on analyzing the compatible state space of the resource interface automata networks, a corresponding reachability graph is constructed, and finally several algorithms are developed for the above problems.
