“…23 Our prior work in this area has stressed the need for modeling cause-and-effect knowledge explicitly as well as the need for a multiscale modeling framework. 16,17,[24][25][26][27][28] Philosophically, our framework is similar to what has been proposed by Rasmussen and Svedung. 29 and by In particular, it shares the main theme discussed by Leveson and Stephanopoulos, 30 but we differ in the conceptual details of the underlying modeling framework.…”

Recent systemic failures in different domains continue to remind us of the fragility of complex sociotechnical systems. Although these failures occurred in different domains, there are common failure mechanisms that often underlie such events. Hence, it is important to study these disasters from a unifying systems engineering perspective so that one can understand the commonalities as well as the differences to prevent or mitigate future events. A new conceptual framework that systematically identifies the failure mechanisms in a sociotechnical system, across different domains is proposed. Our analysis includes multiple levels of a system, both social and technical, and identifies the potential failure modes of equipment, humans, policies, and institutions. With the aid of three major recent disasters, how this framework could help us compare systemic failures in different domains and identify the common failure mechanisms at all levels of the system is demonstrated.

“…These qualitative models are easier to develop and analyze, in comparison with the DAE models, particularly for modeling and analyzing failure modes and hazards. 17,28 However, as they are qualitative in nature, they are limited to certain kinds of queries and can lead to ambiguities.…”

“…The purpose was also to reduce routine and repetitive tasks regarding HAZOP analysis. However, Venkatasubramanian and Vaidhyanathan (1994) began early-on with the concept of propagation of relevant disturbances downstream to different HAZOP nodes. Srinivasan and Venkatasubramanian (1996) also considered batch processes thoroughly dealing with process procedures.…”

Environmental Risk Assessment (ERA) is a decision-making tool that enables affirmative actions, which lead to a safer environment, optimization of manufacturing processes, reduced business risks, and enhanced profitability. It makes an organization proactive and go beyond the paradigm of compliance to enable sustainability. A wide range of techniques are available in the literature, which can be employed in ERA. In this paper, a review of nine major techniques is presented. These techniques are Leopold matrix, Hazard and Operability study (HAZOP), Knowledgebased HAZOP, Fault Tree Analysis (FTA), Event Tree Analysis (ETA), Process mapping, Failure Mode and Effect Analysis (FMEA), What-if analysis, and Checklists. An outline of the origin, history, evolution, applications, and limitations of these techniques is provided. These techniques help in anticipating environmental hazards and implementing an effective environmental management plan.
