Managing interactive collaborative mega project supply chains under infectious risks

The paper proposes the mega project supply chains infectious risks (MPSCIRs) synergy theory, defines the risk propagation speed, propagation density, and risk interconnectivity, distinguishes conventional risks from infectious risks, and identifies the risks facing major projects when passing through the secret channel of supply chains based on system dynamics theory and stability theory, and combining the new characteristics of major project supply chain risks after new technology reforms. Diverse research methods are used to conduct a three-dimensional analysis of MPIRs and major project supply chains (MPSCs) transverse, cutting, and in a hoop. The results suggest that infectious risks in the MPSC system are periodic. Based on the propagation speed, pressure, and direction, the infectious risk propagation capability and propagation energy distribution can be identified. The MPSC can be decomposed into N interactive subsystems. The infectious risks of various subsystems within the load scope should be diffused and coordinated in time. The theory helps in identifying risks and strategies specific to the decision major projects' risk category. The research is demonstrated through an experiment study conducted in major projects' supply chain involving interviews, questionnaires, field observations and focus group meetings through case comparison and simulation study in the supply chain of major projects. In addition, the research can not only prevent major project infection risks (MPIRs) but also ensure the orderly production of major projects.
