“…The DEMATEL method allows for quantitative analysis of the mutual influence degrees between elements, including influence degree, degree of being influenced, along with cause and centrality of each element. This method obtains weight values between the elements considering interrelationships between indicators, so as to adjust and optimize the weight interference due to the non-independence between the product design evaluation indicators [61]. According to Table Ⅰ, the evaluation index's importance differs with mutual influence.…”

In response to the challenge of accurately assessing age-friendly design requirements during the improvement phase of smart products, a novel evaluation model is proposed. This model is grounded in the technology acceptance model and considers the interplay between user weights and requirements. The aim is to establish precise product indicators and development strategies, thereby maximizing user satisfaction and market competitiveness. Initially, design evaluation indicators are derived from the technology acceptance model. Subsequently, the TextRank algorithm and grounded theory are employed to determine the initial weights of these indicators. The DEMATEL method is utilized to analyze the weight of influence relationships between indicators, while the Kano model determines importance coefficients for adjusting weights. Through normalization, final weights are assigned, and the TOPSIS method implements sorting and significance analysis of age-friendly design requirements. Five age-friendly smartphone samples serve as case studies to evaluate and analyze the five age-friendly design requirement indicators. Method comparison and advantage/disadvantage sorting analyses are conducted to validate the effectiveness and feasibility of the proposed approach.

“…It is a systematic analysis method using graph theory and matrix tools. By analyzing the logical relationship and direct influence relationship among the factors in the system, the influence degree and affected degree of each factor to other factors are calculated, and then each center degree and cause degree are calculated as the basis for constructing the model, so as to determine the causal relationship among the factors and the position of each factor in the system 13 …”

Objective Blepharoplasty is a typical complex structural system, which involves many factors and the interaction among them. Therefore, it is the basis of controlling the occurrence of medical complications in blepharoplasty to clarify the hierarchical relationship of various risk factors and find out the key risk factors. Methods On the basis of identifying the risk factors for quality management of blepharoplasty by means of literature research, questionnaire survey and expert interview, the risk factor model of blepharoplasty quality management were analyzed and constructed. The relationship between the risk factors and the degree of influence on the risk factors was studied using Decision‐Making Trialand Evaluation Laboratory and Interpretative Structural Modeling Method, and the hierarchical structure model of the risk factors for blepharoplasty quality management was obtained. Results Six levels of risk factors in quality management of blepharoplasty were identified and classified, and the causal attributes among risk factors were determined. Six key risk factors in quality management of double eyelid surgery were determined according to centrality, and finally the above risk factors were divided into three categories: direct cause, excessive cause, and essential cause. Conclusions This study realizes the comprehensive risk factor analysis of the complex system of quality management of blepharoplasty, which can provide reference for plastic surgeons to make safety decisions of blepharoplasty.

“…Commonly used weighting methods include subjective methods, objective methods, and methods in which subjective and objective weights are combined. Representative subjective weighting methods include AHP 23 , DEMATEL 24 , etc. The subjective method can reflect the knowledge and experience of decision-makers, but it is highly subjective.…”

Nowadays the complex international political situation has caused the shortage of coal supply in the European region. Scholars have done a lot of research on supplier evaluation. However, these studies don’t reflect the variability of the indicators, such as interruption caused by recent war. Coal-electricity-integrated companies have a large demand for thermal coal and high requirements for stable supply, so they need to conduct timely and effective short-term evaluation of suppliers. This paper improves the CRITIC method and uses short-term transaction data for a coal-electricity-integrated firm to evaluate its coal suppliers. The results show that the improved CRITIC method effectively avoids the problem of weight changes caused by conflicting value ranges of indicators, and its evaluation results are more consistent with the actual situation, which can meet the requirements of large coal enterprises for evaluating suppliers.
