To address the difficulty in evaluating and quantifying the value of personalized customized fuel cell test bench （FCTB）， a method is proposed to establish a comprehensive evaluation index system of FCTB， based on the principle of FCTB technology and the actual production process. The fuzzy hierarchical analysis method is used to assign weights to the indexes， taking into account the user’s personalized customization needs. This creates a quantitative value evaluation model， which converts the weighting problem into a constrained optimization problem. An improved harmonic search algorithm is then proposed to solve this problem. By designing a solution vector generation mechanism and a parameter adaptive adjustment strategy， the algorithm improves the solution efficiency and search capability of the traditional harmonic search algorithm. Simulation results show that the proposed method has obvious advantages in terms of computational efficiency and accuracy. It is able to achieve quantitative value assessment of different FCTB scenarios according to the user’s personalized needs.
