| 摘 要： | 根据综合评判法的思想,与灰色系统理论结合,采用灰色聚类分析方法,通过现场提供的各项统计数据,对钻机的综合效益进行聚类评估。评估效果与所取评估权数有关,这主要取决于对综合效益评价中各性能项目在评价中的重要性。评估权数选取的不同则结果也可能有所改变,它的选取主要取决于评价者对各评价项目重要性的认识。算例的评估结果反映出的真实程度令人满意,具有足够的可信度。

| Abstract: | By combining the comprehensive evaluation method with the grey system theoryand using the grey cluster analysis, the comprehensive benefit of drilling rigs is evaluated. The effect of the evaluation is related to the weight number taken in the evaluation, which depends mainly on the importance of each performance index in the evaluation. The result of the evaluation may vary with the difference of the weight number selected. The selection of the weight number of evaluation relies mainly on the cognition of the valuator on the importance of the each item evaluated. Case study proves the evaluation result has adequate reliability. |
