| Under the planned economy system,all the financial investment projects in our country adopt the traditional project management mode,that is,financial investment and the management mode of government functional departments.Because of the lack of professional and technical personnel in the management of project implementation,the decision-making errors in the early stage of the project are caused,the design scheme is adjusted at will,and the phenomenon of "three overruns" of investment occurs frequently,which greatly wastes the financial investment.With the deepening of market economy,government investment projects are entrusted to professional project management companies to organize and implement the whole process management.Accordingly,agent construction system comes into being.The characteristics of agent construction system are that investment,construction,management and use are separated,professional work is realized,and the efficiency of project management is greatly improved.The project management mode of agent construction system is still in the primary stage in our country,and the relevant laws and regulations are not perfect.Because there are many subjects involved in the project construction in the project management mode of agent construction system,and the use of funds and the selection of participating units are controlled by the agent construction unit,the project cost risk under the agent construction system management mode is higher than that under the conventional project management mode.The risk of project cost is greater.Under the agent construction mode,the owner's project cost management not only has the characteristics of "dynamic" and "large amount" of conventional project cost,but also has its own unique characteristics of "hierarchy" and"diversity".Based on the characteristics of the project cost management of government-invested projects under the agent construction system,the owner should give full play to the supervisory functions of all parties involved in the construction,especially the supervision of the agent construction units,establish the contract supervision and restraint mechanism,urge the agent construction units to construct a qualitative and quantitative model of project cost risk management,and urge the agent construction units to introduce the project implementation.The PDCA cycle management system of quality management and schedule management in engineering corrects the deviation affecting project cost in project case management,substitutes the corrected value into the risk management model of project cost,gets more perfect risk-sensitive data,Provides reference for subsequent project cost management,and is conducive to the risk control of government investment owner's project cost management under Agent Construction mode.Based on the agent system model,this paper identifies,evaluates and responds to the risks of the project cost of the owner of government-invested projects.Firstly,this paper expounds the background and significance of the topic selection,sets up the technical route,introduces the concept of agent construction system and its characteristics,combines the existing risk management theory,starts with the risk source of the owner's project cost,divides the owner's project cost risk into legal risk,project decision risk,project management risk,project economic risk and Engineering Technology risk.A risk evaluation index system of government-invested project owner's project cost under agent construction mode is established.The weight of each risk evaluation index is determined by analytic hierarchy process,and the risk grade of each risk factor is calculated by grey evaluation method.The risk comprehensive evaluation model is determined by this method.An example is given to verify the risk comprehensive evaluation model.Finally,the main wind affecting the owner's project cost is given.Risk factors have made risk response measures.Provide investment decision-making to the owner to maximize the efficiency of financial investment. |
