Research On Optimal Selection Of General Contractor Under "F+EPC" Mode In Pre-qualification Stage

In recent years,the scale of China’s infrastructure projects has continued to expand,which has promoted the construction market to vigorously promote BOT,EPC,PPP and other models,as well as continuous exploration of other contracting models.Large-scale infrastructure projects have a large demand for funds,which has led to increased financial pressure on local governments.How to solve the shortage of funds and improve financing capacity to reduce financial pressure has become an issue that the government needs to consider urgently.At present,the "F(financing)+EPC" mode is emerging in foreign countries,which not only meets the government’s trend of vigorously promoting the EPC model,but also solves the problem of shortage of project funds.This general contracting mode with financing function meets the needs of China’s current construction market and has good development prospects.Qualified and excellent general contractors can give full play to the advantages of this model and help the government and itself to achieve win-win benefits.Therefore,a suitable general contractor is an important condition for the successful operation of the"F+EPC" project.Firstly,The thesis combs the concept and characteristics of the "F+EPC" mode,analyzes the various common contracting models,and mainly focuses on the differences between"F+EPC" and "PPP+EPC",summarizes the advantages of the "F+EPC" mode,synthetically analyses the characteristics,roles and selection methods of the general contractor under"F+EPC",and emphasizes the importance of the pre-qualification stage.Then,the index system of the general contractor in the pre-qualification stage is constructed through literature analysis and questionnaire survey.Next,considering the different professional backgrounds of the judge experts,which may lead to the wrong judgment of some indexes,the discrete z-number utility theory model witch considers both the evaluation degree and the reliability degree of the evaluator is used to complete the evaluation of the general contractor,and the fuzzy inference theory is used to optimize the PROMETHEE method to complete the ranking of the general contractors.Finally,a simple example demonstrates the validity of the model.To a certain extent,this paper is helpful for the government and its financing platform companies to understand the"F+EPC" model,and when the "F+EPC" mode is applied,it provides an effective decision-making model and theoretical basis for them to screen the general contractor during pre-qualification stage.
