The objective of this research project is to identify major environment-related system failures using the knowledge gained from a marriage of Life Cycle Analysis (LCA), Failure Modes and Effects (FMEA), and Petri Net Modeling (PEM) techniques. Individually, these tools provide information concerning aspects of the environmental problem. LCA provides information on which and how many critical materials and environmental impacts may be present during an event. FMEA provides information concerning the likelihood of a component failure during an event. PEM provides information about the linkages of systems affected by an event. Taken together, the techniques provide a complete picture of a disaster. It appears from the literature that the methods have never been combined, despite the obvious benefit that can be gained when the methods are used together. In this research, we will develop the methodology to identify and quantify potential system failures using these methods.
The research project currently is carried out by principal investigators from two different universities, the University of Illinois at Chicago (UIC) and The University of Toledo (UT).
Research Work Performed at UIC
Analysis of multiple and sequential failures and reliability assessment of complex systems is a very important task for assessing the impacts of system failures on the environment. The result of the research is a new integrated approach for systems failure analysis that overcomes the limitations of the existing multiple and sequential failure analysis methods. The method is developed based on the concept of counters of Petri net simulation. The developed methodology can deal with complex Petri net structures and compute sequential failure probabilities. The method also is implemented with a hardware-based approach that maps different structures of Petri net into the circuits. It is shown that the hardware-based implementation is fast, reliable, and portable. A prototype for sequential failure and multiple failure analysis of a manufacturing system is developed. The prototype has been tested and validated for the feasibility and accuracy of the method. The contribution of this research is a new integrated approach for reliability and failure analysis of complex systems with multiple and sequential failures. The developed methods perform systems failure and reliability analysis without converting the Petri net into the Markov chain. These methods also can deal with large and complex systems.

When analyzing systems for failure where the probabilities are subjective (and probably underestimated), we are interested in the maximum possible probability of failure, which is given by possibility. When combined with a Petri net for the states and transitions of the system, this allows us to determine whether a subordinate state of interest is possible under the structural rules in place. Currently, we are investigating how possibility propagates through the structure.
We will develop case studies to demonstrate the overall methodology of the research. In addition, we will continue to investigate how possibility propagates through the structural system.
