Risk analysis has been used extensively to inform decisions throughout government and industry for many years. Many methodologies have been developed to perform these analyses, resulting in differences in terminology and approach that make it difficult to compare the results of an analysis in one field to that in another. In particular, many approaches result only in a risk ranking within a narrow area or field of interest, so the results cannot be compared to rankings in other areas or fields. However, dealing with terrorist threats requires prioritizing the allocation of homeland defense resources across a broad spectrum of possible targets. Therefore, a common approach is needed to allow comparison of risks. This presentation summarizes an approach that will allow the results of risk analyses based on using current methodologies to be expressed in a common format with common terminology to facilitate resource allocation decisions.

Abstract The coronavirus disease 2019 (COVID-19) pandemic has seriously damaged the operational harmony of container shipping. Initially, it led to a decrease in the overall throughput of containerized cargo. The industry has faced blank sailings and a lack of container equipment after rising container demand. Operational harmony has not been established for more than a year. Extremely increased freight rates have unprecedently put the shippers in a difficult situation. This study examines the circumstances in terms of the shipper and shipping line relationship and underscores the loose commitment between them. Accordingly, this study questions the mutual commitment of this relationship. This institutionally problematic relationship has become prominent in terms of its consequences in the COVID-19 pandemic era. The problematic part of this relationship is discussed through discourse samples representing different branches of the container shipping industry, using the discourse analysis methodology supported by the literature review. The findings indicate that both shippers and shipping lines recognize that a commitment-based relationship requires decisiveness; however, their priorities in the pandemic era overshadow it. Their mutual commitment may help to alleviate the consequences of any chaos in the future of container shipping, which requires critical projection.

A decision support system was researched and applied to a case study in the petrochemical industry. The participants were an insurance company underwriting the policies of oil and gas refineries located in a major oil producing nation. The Chemical Process Quantitative Risk Analysis methodology was applied as a framework to implement uncertainty quantification and risk analysis using a specialized commercial DSS software product. A gas vapor explosion was simulated at an oil refinery, to predict the fire and radiation damage. Costs and risks were entered into the model based on historical data. Loss estimates were generated for equipment and buildings located various distances (pressures) from the explosion origin. Overall, the DSS model predicted an expected loss of over $14,000,000 USD for equipment located in the 50 meter explosion radius, which represented a loss ratio of almost 52%. The losses predicted from the DSS model were comparable to the literature and to experiences of the case study company. The margin of error from the DSS model was less than ±5% which made it very reliable according to benchmarks.
