【摘要】：城市建筑向高空发展已成为当今社会建筑发展的主要方向，向高空发展的高层、超高层建筑规模庞大，所需运送的建筑材料数量多，施工人员上下班集中，施工过程中产生建筑垃圾多，目前，大量采用各种垂直运输机械进行运输。高层建筑的施工速度在一定程度上取决于施工所需物料的垂直运输速度，因此，垂直运输机械的配置在施工组织中占有很重要的地位。国内外学者针对垂直运输机械的选型、租购决策以及安全施工等方面进行了大量研究，然而，由于影响垂直运输机械配置因素的多样性，仍存在一些问题需要进一步研究。本文主要针对垂直运输机械配置的问题，调查各种垂直运输机械的类型、参数、特点等，收集大量数据，根据配置原则，以及各种配置方案的优缺点，采用了层次分析法理论，建立层次分析结构模型，分别运用商法、差法进行求解，并对商法以及差法的求解结果进行了对比，分析了两种计算方法产生差异的原因，在此基础上对收集的数据进行了修正，重新运用商法以及差法构建判断矩阵，运用数据处理软件Matlab计算出了各层次影响因素的权重排序以及各配置方案的综合评价系数，为高层建筑垂直运输机械配置方案的优选提供了一种方法。主要研究内容如下： 1、本文概述了国内外垂直运输机械使用的研究现状，归纳了决策分析常用的方法，根据前人的研究成果，提出了本文的研究内容以及研究方法。 2、介绍了现阶段垂直运输机械的主要类型，分析了各类垂直运输机械的优缺点，分析了在高层建筑施工时，选择垂直运输机械配置方案应考虑的主要配置原则，以及现阶段的主要配置方案。 3、概述了层次分析法的基本原理以及运用层次分析法决策的基本步骤，根据分析的垂直运输机械配置原则，，对影响垂直运输机械配置方案决策的因素进行了分析，选用12个影响因素建立了层次结构模型，并通过问卷调查法收集了数据，采用商法及差法对收集的数据进行了处理，分别构建了成对比较矩阵；运用Matlab软件对构建的比较矩阵进行了求解，求解结果与具体工程实例吻合较好，验证所建立的层次结构模型是有效的。 4、对商法以及差法的求解结果进行了对比，分析了两种计算方法产生差异的原因，在此基础上对收集的数据进行了修正，重新运用商法以及差法对层次结构模型进行了求解，提出了一些合理性的建议以供施工单位参考。
[Abstract]:The development of urban architecture to high altitude has become the main direction of the development of social architecture today. The high-rise building developing to the high altitude is huge in scale, requires a large number of building materials to be transported, and the construction personnel are concentrated in commuting to and from work. Construction process produces a lot of construction waste, at present, a large number of vertical transport machinery for transport. The construction speed of high-rise building depends to a certain extent on the vertical transportation speed of the materials required for construction. Therefore, the configuration of vertical transport machinery plays an important role in the construction organization. Domestic and foreign scholars have done a lot of research on the selection of vertical transport machinery, rent-purchase decision and safety construction. However, due to the diversity of factors affecting the allocation of vertical transport machinery, there are still some problems that need to be further studied. Aiming at the problem of vertical transport machinery configuration, this paper investigates the types, parameters, characteristics and so on of all kinds of vertical transport machinery, collects a large amount of data, and adopts the theory of analytic hierarchy process (AHP) according to the configuration principle, as well as the advantages and disadvantages of various configuration schemes. The analytic hierarchy process (AHP) structure model is established, which is solved by quotient method and difference method respectively. The results of quotient method and difference method are compared, and the reasons for the difference between the two methods are analyzed. On this basis, the collected data is modified, and the judgment matrix is constructed by using the quotient method and the difference method again. The weight ranking of the influencing factors of each level and the comprehensive evaluation coefficient of each configuration scheme are calculated by using the data processing software Matlab. This paper provides a method for the optimization of vertical transport machinery configuration scheme in high-rise buildings. The main research contents are as follows: 1. This paper summarizes the research status of vertical transport machinery at home and abroad, summarizes the commonly used methods of decision-making analysis, and puts forward the research contents and methods of this paper according to the previous research results. 2. This paper introduces the main types of vertical transport machinery at present, analyzes the advantages and disadvantages of all kinds of vertical transport machinery, and analyzes the main configuration principles that should be taken into account in choosing the vertical transport machinery configuration scheme in the construction of high-rise buildings. And the main configuration scheme at this stage. 3. The basic principle of analytic hierarchy process (AHP) and the basic steps of decision-making by AHP are summarized. According to the analysis principle of vertical transport machinery configuration, the factors that influence the decision-making of vertical transport machinery configuration scheme are analyzed. The hierarchical structure model was established by 12 influencing factors, and the data were collected by questionnaire, the collected data were processed by quotient method and difference method, and the pairwise comparison matrix was constructed respectively. The Matlab software is used to solve the comparison matrix, and the results are in good agreement with the actual engineering examples. It is verified that the established hierarchical structure model is effective. 4. comparing the results of the quotient method and the difference method, analyzing the reason of the difference between the two calculation methods, modifying the collected data, re-using the quotient method and the difference method to solve the hierarchical structure model Some reasonable suggestions are put forward for the reference of construction units.
