The invention discloses a multi-investment integrated construction project dynamic progress controlling method. Based on a critical chain
project management method (CCPM), six correction coefficientsof a buffering area are set, three project characteristics of multi-investment main bodies, integrated construction and project integration have a special influence on the resource constraint degree alpha, the procedure complexity beta, the uncertainty k, the procedure continuing
time ratio P, the procedure position coefficient sigma and the risk
appetite Mu of managers, and thus setting of the buffering area is influenced, wherein the
influence coefficient is shown in the description.
