【Abstract】 The schedule and cost risks of water resources projects are discussed, and a stochastic simulation model for risk evaluation of network schedule and cost is established based on the triangular distribution. The probability distribution and risk curve of schedule and cost are obtained by statistic analysis, providing a basis for risk evaluation of engineering projects. Finally, the model is applied to the simulation of the construction network schedule for a pumping station in Dongshen water supply reformation project, and the schedule and cost risk distributions are also given.更多还原
