Abstract

The work aims to construct an integrated KJ-PCA-G1-TOPSIS design decision model for the research and development of home-based smart intervention products to address the risks of night-time bed-leaving, wandering and potential elopement among elderly Alzheimer's patients. User needs were collected via field interviews and scenario observations. Core evaluation indicators were extracted using the KJ method, and a comprehensive indicator system was established through PCA dimensionality reduction. The G1 method was applied to calculate indicator weights based on expert judgments, and the TOPSIS method was adopted to conduct a multi-attribute evaluation on the alternative design schemes. Through the PCA method, three principal components were identified: comfort and operation experience, safety and collaborative protection, and product attributes and benefits. Weighting results revealed that anti-wandering performance, safety protection and operational convenience were the dominant design priorities. TOPSIS evaluation demonstrated that the home-based unlabeled anti-wandering carpet lamp scheme had the highest degree of relative closeness and outperformed other alternative schemes in comprehensive performance within the given range. The KJ-PCA-G1-TOPSIS model effectively integrates user perceptual needs, statistical analysis, expert weighting and quantitative evaluation, improving the systematicness and repeatability of anti-wandering product design for elderly Alzheimer's patients. This study provides a reference for the home-based smart and unlabeled elderly-friendly product design for night-time wandering intervention and caregiver collaborative reminding, while further prototype tests and real-scene verification are required to validate the scheme's practical effectiveness.
