The invention relates to the technical field of constructional
engineering informatization management, and discloses a constructional
engineering full-period
collaborative management and risk
prediction system, which comprises a resource token definition module, a resource token generation module, a
resource management module and a risk prediction module, and is characterized in that physical elements are mapped into discrete resource tokens configured with unit time
delay charge rates; the process transactional modeling module is used for packaging the process into an atomic transaction unit containing a request and a release instruction; the discrete event rehearsal
simulation engine executes circulation in the
virtual time axis and records the hanging duration; the
deadlock detection module monitors the occupancy topology in real time to identify a loop waiting
closed loop; according to the dynamic priority arbitration logic, an accumulated
lag weight value is calculated according to the product of the rate and the duration, resources are forcibly allocated accordingly to eliminate
deadlock, the dynamic arbitration
algorithm based on the time value gradient is constructed, the physical
lag cost is converted into the calculation weight, and the capacity of the
system for automatically converging to the optimal solution under complex constraints is improved.
