Title: PIPE + - An Environment for Building and Analyzing High Level Petri Net Models


Abstract: High level Petri nets have been developed to model data, structure, and functionality of concurrent and distributed systems in addition to the control flows supported by low level Petri nets. Although high level Petri nets have been around since 1980s, there are few successful tools to support high level Petri nets due to the lack of international standardization. In the past few years, we have leveraged an open source low level Petri net development environment – Platform Independent Petri net Environment (PIPE), and extended it to support high level Petri nets where complex data types and transitions expressed in first order logic formulas can be defined. To analyze high level Petri nets, we have developed a variety of complementary techniques including simulation, model checking, bounded model checking, and term rewriting utilizing mature and cutting edge third party tools including SPIN, Z3, and Maude. We will present our ongoing work in developing this tool environment and demonstrate its use through examples of security patterns and Android permission mechanisms.
