Research On The Influencing Factors Of The Construction Cost Of A City Complex Based On The Analytic Hierarchy Process

In recent years,as competition in the real estate industry has become increasingly fierce,in order to shorten the development cycle,recover funds as soon as possible,and achieve "quick turnover" under the premise of ensuring quality,more and more real estate developers have adopted simulated bills of quantities.Cost management mode,and this mode also brings uncertainty to the cost management in the later stage of construction.The construction phase of the project is the actual completion phase of the project entity.This phase has a long experience,many cooperation units,complex construction interfaces,and huge consumption of various resources.It is easy to waste resources and increase project costs.In order to ensure effective control of the project cost by real estate developers,it is necessary to establish a model and index system to find out the key factors that have an impact on the cost during the construction phase of the project,and to propose targeted improvement measures.This article first uses the existing literature and research results to study the basic theories of project cost influencing factors,cost management development process,and analytic hierarchy process.Subsequently,this article combines the literature and on-site cost management practices,and further analyzes,summarizes and summarizes the factors affecting the cost of the project during the construction phase.Second,according to the principles and ideas of index identification,the influencing factors are further screened and the final index is determined,so as to establish a hierarchical structure model and index system.At the same time,use analytic hierarchy process to determine the weight of each index and put forward the identification method of key factors.Finally,this article takes a city complex project as the research object,based on the proposed key factor identification method and combined with the actual construction status of the project,identifies the key factors affecting the cost of the complex project and proposes targeted improvement strategies.The index system and key factor identification methods constructed in this paper are used as a combination of qualitative and quantitative identification of the project cost factors,making the identification results more scientific and reasonable.The use of this indicator system and identification method to identify the key factors affecting the cost of a city complex project points out the direction that should be focused on improvement in the cost management process of the complex project,and the research results obtained can be the project or the same type of project Provide reference and reference for future cost management work.
