Abstract: In order to study the methods and processes for evaluating the design of rehabilitation
training products for autistic children and to reduce the subjectivity and one-sidedness in selecting a
scheme, AHP and TOPSIS methods were used to comprehensively evaluate the rehabilitation training
products for autistic children. Firstly, the evaluation system for rehabilitation training products was
constructed through literature research and interviews with experts. Secondly, the AHP method was
employed to determine the weight of the evaluation elements, then the experts’ scoring method was
utilized to establish an initial evaluation matrix. After standardizing the processing of matrix, we
obtained weighted normalization matrix, which led to the positive ideal solution and negative ideal
solution. Then the final ranking was in the manner of calculating the distance between each solution to
be evaluated and the ideal solution. Finally, this method was verified. Based on the AHP and TOPSIS
methods, the evaluation method for autistic children's rehabilitation training products realized the
prioritization of 3 rehabilitation training products, which can reduce the subjectivity and one-sidedness
in the evaluation of the design plan and will be conducive to the future rehabilitation training products for autistic children. The method provides experience for design evaluation and program optimization of rehabilitation products for autistic children in the future.

Key words: industrial design, rehabilitation training products for autistic children, technique for order preference by similarity to ideal solution, analytic hierarchy process, design evaluation
