Research On The Full Life Cycle Risk Assessment Of EPC Project Contracts In Water Engineering Based On FMEA Method

Water is the source of life,the essence of production,and the foundation of ecology.With the rapid development of China's social economy and the increasing water demand and water safety requirements brought about by people's longing for a better life,water projects have become an important infrastructure in China's economic and social development.Rapid growth.At the same time,the diversification of water engineering investment subjects,as well as the difficulty of engineering construction,the complexity of technology and environment,and the continuous improvement of engineering quality,safety,environmental protection,construction period and benefits,have raised the need for the improvement of engineering construction management level.higher requirement.In the traditional DDB project construction management model,due to the separation of design and construction,problems such as poor communication between members of the organization,separation of various links,and low management efficiency often occur.With the reform and development of the country's construction field and the continuous exploration of engineering construction,the adoption of the EPC model in water engineering construction has gradually become a trend.As far as the contractor is concerned,the EPC project can bring high profits to it while also presenting greater contract risks.Compared with traditional construction contracting projects,the main reasons for EPC project contract risks are: First,the contractor needs to be fully responsible for the design,procurement,construction and trial operation of the project,and the organization and management,technical requirements,resources and The requirements for capital guarantee capacity are high;second,the contract signing time is in the early stage of the project construction cycle,and the survey and design depth of the project is often insufficient;third,the project contract period is long,the project requirements,construction conditions,social environment,national policy,market environment,etc.The change of factors has a great impact on the project construction.Fourth,it is affected by the supply and demand relationship of the project contracting market.In the EPC project contract,the contractor assumes a large contract risk.Therefore,carrying out EPC project contract risk evaluation research is of great significance to improve the contractor's EPC project risk management level.The main research contents and results of this article are as follows:(1)According to the characteristics of the water engineering EPC project,the contract risk of the water engineering EPC project is divided according to the contract life cycle,and on the basis of the preliminary identification of risk factors based on the FIDIC contract terms,the RII relative importance index value method is used to The project EPC project contract risk index system is optimized.(2)The comprehensive weighting method composed of expert evaluation method and deviation maximization model method was used to determine the weight value of the contract risk index of the EPC project of the water project,and an FMEA based on intuitionistic fuzzy theory and multi-objective multi-objective analysis(MULTIMOORA)Comprehensive evaluation model.(3)The feasibility and effectiveness of the FMEA risk assessment model based on intuitionistic fuzzy MULTIMOORA are verified by examples,and the proposed method is analyzed for sensitivity and comparative analysis.On the basis of theoretical research and empirical analysis,it proposes measures for contract risk management of general contractors under the EPC model.Finally,the shortcomings of the research in this paper are discussed,and the future research direction is prospected.
