Establishment of the Model of Fuzzy Evaluating System for Experiments´ Performances in Course of Surveying and Related Research

Aiming at applying fuzzy evaluating theory to conventional experiments in course of surveying, this paper elaborates the importance of synthesized evaluation of conventional experimentspsila performances in course of surveying. It also discusses the thread of thought used to establish the model of synthesized fuzzy evaluating system of conventional experimental performances in course of surveying as well as ideas concerning how to utilize computer technology in evaluating experimental performances automatically. Taking the experiment of horizontal angle measurements with observational positions as an example, this paper discusses the factor set, the fuzzy index set, and the fuzzy set of factors´ degree of importance for synthesized evaluating system for experimentspsila performances in course of surveying. It also puts forward the thread of thought to design computer programs for synthesized fuzzy evaluation in order to realize the standardized, objective and automatic evaluation of studentspsila performances of conventional experiments in course of surveying. Applying this research to evaluation of conventional experiments´ performances in course of engineering survey, the authors minimize to some extent the effects of subjective, one-sided factors on evaluation of students´ conventional experimental performances. Therefore the objective, fair and scientific evaluation is accomplished and working efficiency of the teacher is improved.
