Abstraction framework and complexity of model checking based on the Promela models

Automated model checking shortcomings is prone to state explosion. In this paper, we propose abstraction framework based on Promela models, and transform the source of Promela models to the abstract target of Promela models. On this basis, we analyze the reasons for the complexity of model checking based on Promela models. Finally we reduce the number of state-generated under the condition of verification property unchanged in the ATM example. These show that the abstraction framework reduce the complexity of model checking.
