Design Process Simulation Based On Information Dependency

A modeling method based on DSM is introduced. In circumstance of iterative task, the ways concerning about the input of data,the generation of stochastic variables and the set of the simulation clock are dipicted. While considering the learning curve of activities, the way is studied express the movable process of a single project and then list the corresponding Monte Carlo simulative block diagram .The program based of EXCEL VBA is also written. The result of a given simulative example shows that the method can simulate complex design activities and plan the project in terms of scientific basis.
