“…Grey relational analysis (GRA) is associated with a broad range of applications across various industries, and many scholars use it for similarity calculations and ranking. For example, Chen et al utilised an improved entropy-based GRA to identify and rank critical causal factors in aviation accidents [9]. Based on the results of GRA, Zhang et al emphasised the prioritisation of wall thickness as the most crucial structural factor in diesel particulate filter design [10].…”

making problem. The common approach involves the prioritisation of road repairs with more extensive surface damages but this does not always align with the actual repair needs. To address this, a method based on the grey correlation theory was introduced to evaluate pavement performance. This method was employed to determine the optimal maintenance time for asphalt pavements. Once the sequence was established, the ideal maintenance schedule for the pre-maintenance sections was determined using a cost–benefit model. This evaluation method is particularly useful for quantitative analyses of the influences of pavement age and traffic volume on pavement performance parameters. The results demonstrate that grey relation sorting effectively weighs the factors and provides rankings for road segments requiring maintenance. A cost–benefit analysis model was used to assess the maintenance sections. This model can guide decisions regarding pre-maintenance sections and assess pavement conditions, thus resulting in outcomes that align better with real-world situations and human judgment. These findings are expected to be valuable for the long-term maintenance of asphalt pavements.

“…Therefore, based on the data-driven acquisition of user needs, the entropy theory is combined with the gray relational method, and the entropy value theory based on fuzzy numbers is used to calculate the weight of the target intention, and then the gray relational theory is used to compare product solutions [3] . The entropy weight gray relational method minimizes the influence of the evaluator's subjective factors on the evaluation results, and considers the interrelationships between various factors [4] , which can comprehensively and objectively evaluate the design performance of the Stewart platform [5] .…”

In order to objectively evaluate the Stewart platform design scheme, this paper uses the data analysis method to summarize the design indicators of the Stewart platform, and builds an evaluation index system. Then, the entropy weight method is used to determine the weight of each evaluation index, which ensures the objectivity and reliability of the evaluation results. Finally, the gray relational analysis method is used to evaluate each design scheme, and the evaluation results are obtained and analyzed. The research results of this paper can provide reference and guidance for the design of Stewart platform, and can also provide reference for the evaluation of other multi-index and multi-level decision-making problems.
