Traditionally, the understanding of environmental sustainability has been examined by studying products and processes that implicitly assume that the systems concerned are functioning at day-to-day, stable, and operational levels. Often, a failure can create an environmental impact significantly greater than could ever be imaged by attempts to perform impact assessment based on normal operating conditions. The objective of this research project was to develop new methods to estimate and predict the system failures that could cause impacts on the environment. Our key research approach was to build these methods based on current technologies, such as life cycle analysis (LCA), failure modes and effects analysis (FMEA), and Petri net modeling.
The research project has been carried out by principal investigators from two different universities, Dr. David He at the University of Illinois-Chicago (UIC) and Dr. Walter Olson at The University of Toledo (UT). The research included the development of the following:
- A novel methodology based on counters of Petri net models for sequential failure analysis of complex systems
- Hardware based implementation approach of sequential failure analysis using maps of Petri net structures into the circuits-based hardware
- An impact analysis methodology for design of products and processes for reliability and quality by integrating FMEA and Petri net analysis. The methodology combines the structural and qualitative analysis of FMEA techniques with dynamic and qualitative analysis of Petri net modeling approach and is able to analyze multiple failure effects and their impacts on reliability and quality of product and process design
- An integrated methodology for assessment of pollution prevention technologies. The failure modes identified by FMEA within the framework of life cycle analysis are mapped into a Petri net model where quantitative effect analysis of combined failure modes and their critical sequences are performed. The results of the quantitative analysis generated by the Petri net model is converted into a Markov decisionmaking process to quantitatively predict the impact of failures on the environment and optimize the decisionmaking in preventing pollution at the source.
New methods have been developed in this research project to estimate and predict the failures of systems that cause impacts on the environment. These new methods have been tested through industrial examples to demonstrate their effectiveness. The research results have been published in professional journals.
