基于模糊综合评价法和着重加权法的水尺计重误差算法研究

Study on the Algorithm of Draft Survey Error Based on Fuzzy Comprehensive Evaluation Method and Weighting Emphasis Method

水尺计重易受多种因素影响而产生误差。结合水尺计重的特点，采用模糊综合评价法与加权着重法设计出误差算法，实现输入风险指标值，就能获取该条件下水尺计重的误差。模糊综合评价法体现出水尺计重误差风险指标多因素、多层次以及部分指标难以量化的特点，而加权着重法则弥补了模糊综合评价法风险衰减的不足。基于模糊综合评价法与加权着重法的水尺计重误差算法可以计算出不同情况下水尺计重工作的误差风险，确保水尺计重误差低于0．5％的技术要求。

Affected by various factors, draft survey often produces errors. Considering the characteristics of draft survey, the fuzzy comprehensive evaluation method was adopted. The algorithm of draft survey error to achieve inputting the value of index was designed, and the value of draft survey error at different condition was obtained. The fuzzy comprehensive evaluation method considers the multiple indicators, multi-layered and some indicators difficult to quantify. Weighted emphasis method makes up for the attenuation of the fuzzy comprehensive evaluation method. The algorithm of draft survey error based on the fuzzy comprehensive evaluation method and the weighted emphasis method can calculate the error risk in different condition, such ensuring draft survey error less than O. 5%.
