Abstract During the process of appraisal of grain industry security, the ascertaining of the index weight is the key problem to decide whether the appraisal result is scientific. Triangular adjustable fuzzy number is adopted to investigate the experts' suggestions in this paper, which effectively avoids AHP's problem of consistency check. The multi-experts decision is made convergence twice by means of the cluster analysis theory. The first convergence resolves the problems of abnormal value, which reduces the electivity and subjectivity of the experts' suggestions. The second convergence adopts the similarity coefficient as weight to make comprehensive weighted of the selected experts' suggestions, which will consequently obtain the more reasonable comprehensive weight.
