Narrow Results

Gas refineries are an important part of the energy supply in the world but they may produce byproducts like emissions too. Thus, both technical performance and environmental execution are important and need to be analyzed. Iran is the third-highest producer of natural gas in the world. It produces 6.5% of the natural gas in the world. This paper rummages the environmental and technical performance of Iranian gas refineries through data envelopment analysis (DEA), which is a strong frontier analysis approach is used in this study. Although the primary result shows a rather good performance of Iranian gas refineries overall, more potentials are found for improvement. We find 6% technical potential and 8% environmental potential for improvement which is still a considerable amount. Thus, national and international policymakers should consider this potential for better production and supply of natural gas. We also provided an empirical robustness check to enrich our findings.

Organizations use many tools to perform risk analysis. Failure Mode and Effects Analysis (FMEA) is one such tool which ranks highly as a modern and widely used tool. Despite its advantages, FMEA experiences limitations within the insurance industry. The main aim of this paper is to enhance the capability of using FMEA in the insurance industry. As with any process, FMEA is prone to failure if its weaknesses are not recognized and supplemented with other activities. This paper seeks to overcome the issues by obtaining the probability distribution of the Risk Priority Number which is an indicator of the overall risk in FMEA. Finally, an empirical study in the area of gas industry is used to demonstrate the capability of the new idea.
