【摘要】：施工单位在质量策划中因缺乏操作性强的手段,往往以工程总成本最低为原则,忽略因满足业主质量要求带来的潜在收益。为了让施工单位可以站在企业利润最大化角度进行施工质量策划,本文做了如下研究:本文将企业利润最大化目标转化为单项工程综合效益最大化目标,并将质量水平对市场份额的影响视为工程的潜在收益,从而使施工单位可以站在综合效益角度对单项工程进行质量策划。为解决潜在收益与质量损失成本不易量化的难题,文本采用模糊综合评判法进行策划,从而获得综合效益最大化下的最佳质量水平与实施方案。为了建立模糊综合评判法需要的质量水平被择集和与其对应的施工影响因素集(即实施方案),本文通过对顾客满意度调查问卷的设计与分析过程来识别业主的质量要求,用满意度指标反映其完成程度;将导致返工的质量控制关键点视作施工单位的质量要求,用质量控制指标反映其完成程度,进而用各项指标作为质量水平细化指标建立完善的质量水平备择集;同时,从4M1E角度出发划分影响各细化指标的实施方案,并通过分析质量统计数据以识别不同等级质量水平细化指标与不同等级实施方案的对应关系,进而建立质量水平被择集对应的施工影响因素集。本文以建筑工程一项重要的子分部工程桩基工程为实例,对文中研究的质量策划方法进行实践,策划出该工程的最佳质量水平与实施方案,说明了本文研究内容的可操作性;并通过竣工后的满意度回访与质量控制点验收情况统计验证了实用性。
[Abstract]:Due to the lack of operable means in quality planning, construction units often take the lowest total project cost as the principle and ignore the potential benefits brought by meeting the quality requirements of the owners. In order to make the construction unit plan construction quality from the angle of enterprise profit maximization, this paper has done the following research: this paper transforms the enterprise profit maximization goal into the single project comprehensive benefit maximization goal. The influence of the quality level on the market share is regarded as the potential benefit of the project, so that the construction unit can plan the quality of the single project from the angle of comprehensive benefit. In order to solve the difficult problem that the potential profit and the cost of quality loss are not easy to quantify, the text adopts the fuzzy comprehensive evaluation method to plan, so as to obtain the best quality level and implementation scheme under the maximization of comprehensive benefit. In order to establish the selection set of quality level required by fuzzy comprehensive evaluation method and the corresponding construction influence factor set (that is, implementation scheme), this paper identifies the quality requirements of the owner through the design and analysis process of the customer satisfaction questionnaire. The key points of quality control that lead to rework are regarded as the quality requirements of the construction units, and the quality control indexes are used to reflect the degree of completion. Then using each index as the quality level refinement index to establish the perfect quality level alternative set, at the same time, from the 4M1E perspective, divide the implementation scheme that affects each refinement index, By analyzing the statistical data of quality, we can identify the corresponding relation between different grade quality level refinement index and different grade implementation plan, and then establish the construction influence factor set corresponding to the selected set of quality level. Taking the pile foundation engineering of an important sub-branch engineering as an example, this paper carries on the practice to the quality planning method studied in this paper, and plans out the best quality level and the implementation plan of the project, and explains the maneuverability of the research content in this paper. The practicability is verified by satisfaction return visit after completion and acceptance statistics of quality control points.
