| In recent years,with the increasingly fierce competition in the construction market,the operational risk of projects under construction has become the main risk faced by such enterprises.The construction projects of construction enterprises have the characteristics of long production cycle,huge investment,easy to be affected by the environment,and many project participants.In order to ensure the efficient operation of the construction projects within the expected scope,it is necessary for construction enterprises to make objective evaluation and prediction of various operational risks,and make control optimization strategies within the effective time by analyzing the risk elements and their interaction,In order to minimize the operation risk and maximize the benefit of the construction enterprises.Based on this,this paper takes a construction enterprise as the research object,and collects data through literature review and level by level interview.And on this basis,the use of cost control theory and analytic hierarchy process around a construction enterprise in construction project operation and management risk analysis,first of all,the main risk index screening,the establishment of risk hierarchy.Through the research,it is determined that the risk of operation and management of construction projects in a construction enterprise is mainly concentrated in four aspects: resource allocation,project control,operation system and technical management.Secondly,based on the PEST analysis of the macro operation environment of a construction enterprise’s construction projects,and Porter’s five forces model analysis of the medium industry environment,this paper analyzes the external environmental factors of a construction enterprise’s construction projects;At the same time,this paper analyzes the internal environment of construction enterprises in construction projects,and finds out the existing disadvantages of a construction enterprise,namely,bidding disadvantages,cost management disadvantages,supply chain management disadvantages and internal operation management disadvantages.Finally,through the SWOT analysis of the enterprise,the strategy analysis matrix is formed,the strategy combination is constructed,and the most suitable risk control strategy st strategy is found,that is to optimize the risk control first,and then the second development.Thirdly,in order to solve the four major risk problems of construction projects in a construction enterprise,this paper puts forward specific operational strategies on the basis of SWOT matrix,that is,to strengthen the effective control of bidding risk;to strengthen the effective control of bidding risk;Through the construction of cost control system,clear cost control principles;Based on different types of resources and different stages of cost control,to achieve effective control of cost risk;Through optimizing the value chain,building the e-commerce platform of building materials,establishing the industry credit system and supplier evaluation system,the risk of supply chain management can be effectively controlled.Finally,combined with the risk control strategy of this paper,how to carry out the risk control of a construction project in a construction enterprise is designed,and the specific risk control measures are put forward. |
