摘要
为了量化研究建筑工程检测机构的检测能力,建立了基于检测参数的评价模型。将检测过程中的检测成本、检测难度和计算难度定义为机构检测该参数所需的“技术水平”,构建了检测参数技术水平的评价指标体系。再运用层次分析法确定了各指标的权重,并建立了打分标准,计算了参数技术水平的分值,范围为1到4分。基于参数数量、参数平均值和大于3的参数分值总和这3项指标,利用熵权法计算了各自的权重,建立了建筑工程检测机构检测能力的评价模型。通过对10家不同规模的建筑工程检测机构的评价结果与实际情况对比,验证了评价模型的合理有效性。研究成果为建筑工程检测机构检测能力的量化评估提供了有效手段。
To quantify the testing capabilities of construction engineering testing agencies,an evaluation model based on testing parameters was established.The detection cost,detection difficulty,and computational difficulty in the detection process were defined as the"technical level"required by the agency to detect the parameter,and an evaluation indicator system of the technical level of detection parameters was constructed.Subsequently,the Analytic Hierarchy Process(AHP)was employed to determine the relative importance of each indicator,and scoring criteria were established to calculate the scores for parameter technical levels,which ranged from 1 to 4 points.The weights of the parameters were calculated using the entropy weight method,based on the number of parameters,the average value of parameters,and the sum of scores of parameters greater than 3.This resulted in the establishment of an evaluation model of the testing capabilities of construction engineering testing agencies.Finally,the evaluation results of 10 construction engineering testing agencies of different scales were compared with the actual situation to verify the rationality and effectiveness of the evaluation model.The research findings provide a robust and effective means for the quantitative evaluation of the testing capabilities of construction engineering testing agencies.
