Abstract:
To implement the quality management and supervision (QMS) of hydraulic engineering projects, the Ministry of Water Resources of the People's Republic of China has formulated and issued the Measures of Supervision and Inspection of Hydraulic Engineering Quality and Work Safety , the Measures of Supervision and Inspection of Operations and Management of Hydraulic Engineering and the Measures of Supervision and Inspection of Hydraulic Engineering Contacts ("Three Measures" for short) for the supervision and inspection. The supervision and inspection work based on the "Three Measures" involves the QMS of the stakeholders and the hydraulic engineering projects. However, the related evaluation based on the "Three Measures" is qualitative, not quantitative. Thus, the QMS of hydraulic engineering projects needs to be improved, and a quantitative evaluation system is needed to compare different departments involved in the same project, different projects, and different provinces. Analytic hierarchy process (AHP for short) was selected for designing the evaluation system. The qualitative indicators in the "Three Measures" was taken as the quantitative indicators of the evaluation system. The evaluation indicator system was designed as seven layers, including 2,112 indicators which is in accordance with the "Three Measures". The indicators score system was designed combining the methods of the point-deduction system and the one-vote veto system. To improve the accuracy and reliability of the evaluation system, the weights of the indicator evaluation system was designed, compared, and selected. The importance of elements was divided into "normal", "important" and "critical", and the corresponding weight of the indicator of the evaluation system was set to one, three, and nine, respectively. The quantitative indicator evaluation system of QMS was established through the comprehensive index method using the selected weights and indicators score system. Additionally, this evaluation system of QMS has a flexible structure and can be spliced and deleted according to management requirements and the critical parts of supervision. The indicator evaluation system of "quality management" and "work safety management" were selected and established, and different hydraulic engineering projects were applied in seven provinces in China. These seven provinces were named A1 to A7 respectively. Two aspects of different stakeholders QMS in the projects and different projects QMS in different provinces were also evaluated. The quality management evaluation results of different stakeholders indicate that the level of the construction department is the highest, and the quality examination department and the building department are both at the lowest level. The evaluation results of work safety management in each stakeholder indicate that the construction department and the survey and design department are at the highest level, and the building department and the supervision department are at the lowest level. The evaluation scores of quality management in each province indicate that A2 and A7 are in the highest and lowest levels of quality management, respectively. The evaluation scores of work safety management in each province indicate that A6 and A5 were at the highest and lowest levels of work safety management, respectively. The comprehensive evaluation scores of quality management and work safety management in each province showed a tiered distribution, of which, 28.6% of the provinces were "excellent", 42.9% "good", and 28.6% "qualified", and no "unqualified" appeared.The average evaluation scores of work safety management were generally higher than those of quality management in provinces. The comprehensive scores indicated that the provinces were all above "qualified" and showed a three-tiered distribution. The scores had a large difference among these provinces. The quality and work safety management comprehensive analysis showed that the building departments were the most problematic in all provinces.
