【摘要】 目前,我国大型工程建设面广量大,在世界上和历史上都是空前的。在这些大型工程建设中,不少项目设备,特别是大型设备所占比重很大,甚至成为整个工程建设的核心或主要工程量。如何在工程建设中引入和发挥监理制,并用现代管理理论、系统科学和控制科学的思想及方法使设备工程监理科学化是一个值得研究的问题。本论文从质量、投资、进度等方面进行了较为系统的研究,主要贡献如下: 1.针对到目前为止,设备工程监理尚没有较完整和公认的定义,本文尝试对此进行了界定,提出了设备工程监理的概念并对其内涵进行了界定。 2.将控制科学的基本原理应用于设备工程监理系统,研究了设备工程的控制流程、控制类型等内容,构建了设备工程监理的基本框架。 3.建立了适合于设备工程项目目标控制的一般模型,即单目标控制的统计偏差分析模型、单目标控制的预测偏差分析模型、多目标控制的综合偏差分析模型,以及设备工程项目质量、投资、进度目标控制界限的确定方法。 4.按设备工程项目各个建设阶段的投资控制要求建立了控制模型,并对各控制阶段的不确定影响因素也一并给予集成考虑,对设备工程项目投资控制进行了集成建模。 5.运用系统可靠度最优配置理论,分析了合理协调设备工程施工中质量成本控制关系的可行性,建立了设备工程质量成本关系模型。解决了设备工程项目质量成本控制的优化问题。 6.建立了设备工程监理的投资控制系统方法,即设备工程投资控制的偏差分析法。论述了设备工程投资偏差分析法的原理及其应用。利用这种投资控制方法,可以实现设备工程项目投资控制的定性和定量分析相结合。 7.建立了设备工程监理的进度控制系统方法,包括进度控制的曲线比较法和进度控制的偏差分析法。利用这两种进度控制方法,均能直接判断进度状况,并计算出相应的进度偏差值。 8.利用运筹学中的最小截集—最大流原理,建立了设备工程时间成本优化数学模型,通过求解最小截集问题,得出设备工程时间成本优化模型的解法,有效地解决了复杂设备工程进度计划网络时间成本优化问题。 9.将遗传算法引用到设备工程资源工期优化中,解决了设备工程资源有限
【Abstract】 Now a lot of large-scale engineering projects are under construction in our country and this tendency is growing up. The equipment in quite a number of these engineering occupies an important place even plays a leading role. So it is well worth of researching that how to introduce and efficiently use equipment engineering supervision in engineering construction. This dissertation will research the quality, cost and time control, and the main contributions are as follows:1. A concept of equipment engineering supervision is put forward and defined.2. The control process and type are studied, and a basic architecture of equipment engineering supervision is built up.3. Some target control models, including the statistical warp analysis model and forecast warp analysis model of single target and multi-target control warp analysis model, are built. Then a novel method is proposed for defining the quality, cost and time of engineering projects.4. Some integrated cost control models are built.5. The cost control method with cost warp analysis is proposed.6. By using the system reliability and optimum allocation principle, feasibility of the relations between quality control and cost control reasonably is analyzed when the equipment engineering is in progress. The beneficial research for the application of the system reliability allocation principle in quality and cost control is made.7. We propose the time control methods including cure comparison and warp analysis method.8. A time-cost optimization model is given by means of introducing the min-cut max-flow theory, and a solution to this model is provided. The result shows that this method can solve effectively time-cost optimization problem in complex project plan.9. The optimization problem of resource- constrained allocation is solved by the adoption of the genetic algorithm technique in resource planning optimization. This method has its practical application value for the resource planning optimization of project.
