Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Computer-aided process engineering provides industrially widely applied software solutions that can be successfully exploited for safety analysis. In this work, simulation-based hazard identification tool with demonstrative applications is proposed. HAZOP study was selected as the base methodology and commercial simulator Aspen HYSYS was employed as the simulation environment. Two case studies, ammonia synthesis plant and propylene glycol production, differing in employed unit operations were selected to determine robustness and reliability of the proposed tool. Hazards and operability problems were identified utilizing advanced mathematical algorithms such as parametric sensitivity analysis coupled with runaway effect detection and steady state multiplicity identification. Reactive systems of both case studies are well known for their nonlinear behavior and the presence of steady state multiplicity. This phenomenon was successfully simulated using Aspen HYSYS built-in solver.
