Study On Cost Model Optimization And Application Of Shanty Renovation Project For Farmers In Changsha City

With the rapid development of China’s economic construction and the acceleration of urbanization construction,as one of the important content of the people’s livelihood project shantytown renovation project has been widely paid attention to,because of the huge amount of investment in shantytown renovation project,so the project cost management has been an important position in the project management.As the core part of project management,project cost control has been throughout the whole project construction.Engineering project from project preparation,engineering design to engineering construction and later operation and maintenance use are inseparable from efficient cost management.In order to improve the overall benefit of construction projects and further development,it is necessary to do a good job in engineering cost management.This paper aims to forecast construction and installation cost reasonably by constructing a fast and efficient forecast model.Through the study of the literature,it is found that the grey model is simple and efficient,and it does not have high requirements for basic data.The purpose of rapid prediction can be achieved through a small amount of data.Therefore,it is considered to introduce the grey model into the prediction of construction and installation costs.A grey model is a model that combines the basic data of the past and present to predict future data,thereby projecting possible future trends.Through the gray prediction model as the object,this paper studies the optimization application of the cost model of the shantytown reconstruction project for farmers in Changsha city,analyzes its application in the field of engineering cost prediction,specifically combined with the composition of engineering cost,carries out a detailed analysis of the correlation between different costs and the impact on the total cost.Then the classical model and optimization model are used to predict the total cost of specific cases,and then the prediction method that can improve the prediction accuracy is proposed.Finally,based on the actual data of a shanty reconstruction project for farmers in Changsha that is actually completed in 2021 and the results calculated by the established classical and optimized prediction model,a more suitable model for cost prediction is found by comparison.It provides a scientific and reasonable basis for the reasonable forecast of project cost.
