Identification and Quantitative Assessment of Complexity of Megaproject
To strengthen the understanding and effective measurement of the significant complexity characteristics of megaprojects,a quantitative evaluation method for the complexity of megaprojects is established to provide an effective method for project managers to accurately control the complexity of projects.Through literature review and expert interviews,the definition and connotation of megaprojects and their complexity are clarified.Based on the theoretical framework of technology-organization-environment(TOE),the complexity evaluation elements of megaprojects are identified,the questionnaires are formed through three rounds of questionnaire design,the reliability and validity of the 94 questionnaires recovered are tested,factor analysis is then carried out,after which the complexity measurement system of megaprojects including three dimensions(technical complexity,organizational complexity,and environmental complexity)and 17 secondary evaluation indicators is constructed.Furthermore,based on the Network Analytic Hierarchy Process(ANP)model,the weight coefficients of each index are calculated,the complexity calculation formula of megaprojects is proposed,and the case analysis is carried out on this basis.The results show that through the three-level complexity management strategy system,the quantitative evaluation of the complexity of megaprojects makes the evaluation information sources clear,accurate and reliable,which not only realizes the macro control of the overall complexity of the project,but also helps to clarify the key control dimensions and specific measures in the complexity management plan.
