Metric Options: CountsSelecting 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
Failure mode and effect analysis (FMEA) is the most commonly used method for quality and reliability analysis of industrial robots. FMEA is important for improving the quality and reliability of industrial robots by identifying potential failure modes and analyzing possible consequences. In order to enable FMEA method to solve relevant engineering problems in complex and uncertain working environment of industrial robots, this paper proposes a reliability analysis method based on double hierarchy hesitant fuzzy linguistic term set(DHHFLTS) and tomada de decisao interativa e multicritevio (TODIM). First, in complex and uncertain environments, we use a DHHFLTS for failure mode evaluation, which can truly portray people's hesitation in this particular environment. Then, the weights of each influencing factor are calculated according to the maximum deviation method of evaluation information. The maximum deviation method allows for capability gaps between evaluation members, i.e., it does not need to calculate the weight of evaluation members separately, which simplifies the calculation process of the method. Finally, the relative dominance and global dominance of failure modes are calculated by TODIM, and then the failure modes are ranked according to the global dominance. At the end of the paper, an example of failure mode analysis for a six-axis industrial robot is used to show the specific implementation process of this method and to prove the practicability and reliability of this method.
