APPLICATION OF THE METHOD OF FUZZY SYNTHETIC EVALUATION AND CLUSTER ANALYS IS TO STEADINESS ANALYSIS OF LEVELLING SURVEY NET

In this paper, the method of Fuzzy Synthetic Evaluation and Fuzzy Ctuster Analysis has been used to judge the steadiness of levelling survey net in Weifang. The definition of the subfunction is based on judgement of four factors individually. The levelling net points are divided into three grades. The steady factor of evaluation set is obtained by the method of Fuzzy Cluster Analysis, then the steady points are separated by the method of Fuzzy Cluster Aalysis.
