“…The basic idea is to rank the alternative samples into optimal and inferior solutions ( 46 ). To improve the factor analysis method using the TOPSIS method, the best value and the worst value of the factor scores obtained from factor analysis can be used as the optimal and worst solution, and the distance between each sample and the optimal and worst solution is calculated, and then the relative closeness of the calculated samples to the optimal solution is computed, and finally the evaluation results of each sample are obtained ( 46 , 47 ). The specific steps are illustrated as follows.…”

To quantify and analyze the psychological reactions of drivers at the entrance zone of a road tunnel, drivers’ physiological data (pupil area, saccade range, saccade speed, heart rate, and breathing rate) were collected using the eye-tracking system in a real driving environment. A psychological load model was developed to quantify the multiple psychological indicators and analyze the change of psychological load at different times and locations based on the TOPSIS (technique for order preference by similarity to an ideal solution) improved factor analysis method. Sensitivity analysis was used to explore the effect of psychological indicators on psychological load. Results of tests conducted at different times of day (12:00, 15:00, and 18:00) show that psychological loads increase slowly to 0.52, 0.38, and 0.23, respectively, when outside the tunnel entrance (from −100 m to −50 m), increase dramatically to a maximum value (1, 0.84, and 0.71) when approaching the tunnel entrance (from −50 m to 0 m), and decrease dramatically to 0.61, 0.58, and 0.41 when first entering the tunnel (from 0 m to 50 m), and then decrease slightly to 0.20, 0.13, and 0.12 when driving inside the tunnel (from 50 m to 200 m). The result also shows that the proportions of saccade speed, pupil area, and saccade range are larger than heart rate and breathing rate. Moreover, the psychological loads of drivers are considerably lower at 18:00 than at 15:00 and 12:00, and the psychological loads near the entrance are considerably larger than inside or outside the entrance.

“…Step 5: Calculating the Objective Weight of the Indicator by Applying FA. e FA is to reduce the variables with complicated relations into a few comprehensive factors by studying the dependence relation inside the correlation matrix and adopting the idea of dimensionality reduction [50]. In this study, the collected data were processed by FA to obtain the objective weight of each indicator.…”

Recent frequent “thunderstorm incidents” of the internet financial platforms (IFPs) have caused the panic of investors. In order to measure and reduce the investment risk of IFPs, the focus of this study is to evaluate the reputation of IFPs regarding investment risk. First, the reputation evaluation indicator system of IFPs is constructed from two dimensions of direct and indirect reputations. Then, based on this system, an improved fuzzy evaluation approach (IFEA) integrating the method of fuzzy comprehensive evaluation (FCE), the analytic hierarchy process (AHP), and the factor analysis (FA) are proposed for evaluating the reputation of IFPs. Finally, a case study based on the data of 20 peer-to-peer (P2P) lending platforms from “Home of Online Loans” (HOL) in China is used to illustrate the IFEA. Results show that the IFEA can reduce uncertainty and randomness in the determination process of indicator weight and membership degree and therefore accurately obtain the reputation level of IFPs and help investors make better decisions. Meanwhile, the key factors in determining the reputation of IFPs are identified, thereby improving the reputation level of the IFPs.

Objectives: This paper constructs a comprehensive evaluation index of the traditional Chinese medicine (TCM) medical service system and summarizes the development of TCM medical services in China. Methods: We chose 31 provinces' TCM hospitals as research objects. The data were obtained from the Health Statistics Yearbook from 2013 to 2018 and from the National Statistics of Chinese Medicine from 2012 to 2017. The approaches to factor analysis and TOPSIS are used in this paper. It is found that the comprehensive evaluation indexes of the TCM medical service system can be divided into 4 first-level indicators and 14 second-level indicators. Results: The development of the TCM medical service system in China is unbalanced and inadequate. North China and East China are generally superior to Northwest and Southwest China in terms of revenue and expenditure for TCM medical services. The per capita of medical resources in the Southwest and Northwest are stronger than those in Central and South China, but overall medical resources are weaker than those in East China and North China. TCM medical service institutions in East China, South China and Central China have achieved better service results and higher economic benefits with less resource input, which further indicates the efficient allocation of resources and the balanced operation of TCM medical service institutions. Conclusion: The development of China's TCM medical service system shows the imbalance and inadequacy of "East is strong, West is weak" and "South is superior, North is inferior."
