Research On State Recognition And Grade Evaluation Of Construction Contract In Large Scale Construction Projects

The project environment is complex,which makes a series of characteristics of large-scale construction project construction process is tedious,the project is expected to be difficult to achieve the desired results.Through interviews with industry experts found that in the process of failure to find and deal with the risk factor is the cause of the project,the key reason for the cost overruns.In order to find out the incentives,managers must be in the project implementation phase,always grasp the dynamic performance of the project.Therefore,this paper combined with the domestic large-scale project status establish a contract status evaluation model,through the measurement of the contract state to control large project performance status,timely risk warning.First of all,this paper improves the definition of contract status.Based on the concept of the system theory,this paper argues that the contract state is composed of five systems: the project environment system,the stakeholder communication system,the project implementation system,the resource supply system,the project organization management system.This paper analysis the contract state of large projects by these five systems.Secondly,the evaluation index system is established by reading a lot of literatures,collecting related information of large-scale construction projects,and through a large number of questionnaire survey,This paper uses rough set attribute reduction principle,selects the key evaluation index of contract condition.Finally,the evaluation model based on entropy weight set is established.In this model,the deviation between the actual state of the contract and the contract plan state is divided into five grades,and the higher the deviation level is,the higher the deviation is.In this paper,through the analysis of the same degree,the degree of difference and the degree of difference of the contract status indicators,the deviation degree of the overall status of the contract state and the contract plan state is obtained.Since then,in order to study the deviation reasons,this model further set pair analysis,find out the reality of every index in the index system of comprehensive value associated with the planned value of the degree,in order to dig out the specific reasons for this deviation,provide a basis for decision-making to take corrective measures.This paper is based on the contract status,measure to carry out large-scale overall project performance,to make up for lack of the process control means,in a systematic way,timely correct interference factors in the program to make the project within the scope of the healthy operation.
