【摘要】：工期、成本、质量一直以来是高层住宅楼工程项目施工过程中管理控制的最主要三大目标,也是承包商(承建方)最关心的工作目标。项目业主单位、监理单位以及施工承包单位,其工作内容都要围绕这三大目标而展开。虽然工期、成本、质量各自的内涵和控制方法各不相同,但是它们之间却存在着相互关联,即它们之间是对立统一的关系。从施工总承包单位的角度而言,要使高层住宅楼项目工期、成本、质量三大目标同时达到最优几乎是不可能的。在此,仅从高层住宅楼工程项目施工总承包单位的角度出发,旨在探讨一种高层住宅楼工程项目“质量、成本、工期”三大目标综合优化的方法。首先经过总结分析有关国内外相关领域研究文献,探讨了工期、成本、质量综合优化研究领域目前存在的主要不足及开展研究本课题的意义。之后,分析界定了论文的研究对象——高层住宅楼工程项目,并且简要分析了研究出发的角度,即施工总承包模式。然后,在参考总结相关参考文献中工程项目工期、质量、成本三大目标相互间基本关系的前提下,基于线性多目标规划相关理论,探讨构建了以工程质量为第一优化目标、以施工成本为第二优化目标、以施工工期为第三优化目标的“质量-成本-工期综合优化模型”。该模型主要做了以下探索:(1)考虑了高层住宅楼项目施工过程中各项施工任务之间的搭接关系,这种搭接关系可直接反应在工程项目工期优化计算中;(2)考虑了高层住宅楼项目在兰州市地区范围内施工必不可少的“冬休期”,“冬休期”的长短不仅影响工程项目工期的长短,而且影响施工承包方的施工成本,这种相互关系在该模型中得到了充分体现;(3)探讨了基于挣值法的工期-成本-质量动态控制程序,对工程项目工期、成本、质量实施动态控制。最后论文针对一个兰州市某住宅小区的一栋高层住宅楼实际工程项目,建立了该项目的“质量-成本-工期综合优化模型”,并且进行了优化计算。从优化计算的结果来看,以质量为第一优化目标、以成本为第二优化目标、以工期为第三优化目标的综合优化模型既能满足施工单位的期望,也能满足建设单位的要求。
[Abstract]:The construction period, cost and quality have always been the three main objectives of the management control in the construction process of the high-rise residential building project, and are also the most concerned work objectives of the contractor (contractor). Supervision unit as well as construction contracting unit, its work content should revolve around these three big goals, although the time limit, the cost, the quality respective connotation and the control method are different. However, there is a mutual correlation between them, that is, they are the unity of opposites. From the point of view of the construction general contracting unit, it is necessary to make the construction period and cost of the high-rise residential building project. It is almost impossible to achieve the optimal quality three goals at the same time. In this paper, only from the point of view of the general contracting unit of the construction project of the high-rise residential building project, the purpose of this paper is to discuss the quality and cost of a high-rise residential building project. The method of comprehensive optimization of time limit "three major objectives". Firstly, through the summary and analysis of the relevant domestic and foreign research literature, the paper discusses the time limit and cost. The main deficiencies in the research field of quality synthesis optimization and the significance of carrying out the research. Then, the paper defines the research object-high-rise residential building project. And a brief analysis of the point of view of the study, that is, the general construction contract mode. Then, in the relevant reference literature in the project duration, quality, cost of the three major objectives of the premise of the basic relationship between each other. Based on the theory of linear multi-objective programming, this paper discusses the construction of the project quality as the first optimization goal and construction cost as the second optimization goal. The "Quality-Cost-duration Comprehensive Optimization Model", which takes the construction period as the third optimization objective, has been explored as follows: 1). The overlap relationship between various construction tasks in the construction process of high-rise residential building project is considered. This kind of overlap relation can be directly reflected in the optimization calculation of the project duration. (2) taking into account the "winter break", which is essential for the construction of high-rise residential building projects in Lanzhou area, the length of the "winter off period" not only affects the duration of the project construction period. Moreover, this relationship is fully reflected in the model, which affects the construction cost of the construction contractor. 3) the dynamic control program of time-cost and quality based on earned value method is discussed, and the project duration and cost are discussed. Finally, aiming at an actual project of a high-rise residential building in a residential district of Lanzhou City, a comprehensive optimization model of quality, cost and time limit is established. From the results of optimization calculation, quality is the first optimization objective and cost is the second optimization goal. The comprehensive optimization model with the time limit as the third optimization objective can not only meet the expectations of the construction units but also meet the requirements of the construction units.
