Construction of Off-site Pension Satisfaction Evaluation System Based on Rough Set Theory

Abstract

Due to the aging of the population, the large number of "421" families has caused the traditional old-age care model to suffer severe impacts and new models of old-age care have emerged. First, in light of the more chaotic division of the current old-age care model, we explored the connotation of a new type of old-age care model—off-site pension, then aimed at the lack of systematization and standardized evaluation system for remote old-age care. Starting from the factors affecting the satisfaction of the off-site pension, the theory of rough sets was introduced and an intelligent evaluation model for satisfaction was established. Using the rough set method, a hierarchical calculation method was used to achieve the objective weighting of each index. Finally, through strength analysis and model earnestness, the rational validity of the rough set intelligent evaluation model was verified.
