基于Vague相似度量理论的园林喷灌设计方案评价方法

Research on an Evaluation Method of Landscape Spray Irrigation Design Schemes Based on the Vague Similarity Measure Theory

在描述Vague之间的相似度量与加权相似度量方法的基础上,提出了方案评价所采用的评价指标体系,形成了一套喷灌设计方案评价新方法.在园林喷灌设计方案评价中,Vague集之间的相似度量是评价设计方案接近期望方案(理想方案)的度量,相似度量值越大,设计方案接近期望方案越好.通过实例阐明Vague集之间的相似度量在喷灌设计方案评价中的可行性,方案评价取得了较为满意的结果.

Methods of similarity measure and weighted similarity measure in vague,program evaluation index system used in the evaluation and a new evaluation method of the landscape spray irrigation design plan are described.The similarity measures between Vague sets evaluated the close degree between the spray irrigation design scheme and the desired scheme（idealscheme） in the evaluation of spray irrigation design schemes.The bigger the value of similarity measure was,the better close degree between the spray irrigation design scheme and the desired scheme was.The method was illustrated that it is feasibble in the evaluation of landscape spray irrigation design schemes by using the similarity measures between Vague sets.The scheme evaluation obtained satisfactory results.
