Abstract: A project scheduling model based on Dependency Structure Matrix (DSM) was proposed. In this model, activity relationship DSM was employed to describe the sequential, parallel, overlapping and time-window constraint-dependent relationships among activities, an activity probability DSM was used to describe rework and iteration during activity execution due to uncertain factors, and the activity learning ability was also taken into consideration. Moreover, procedures were provided when parallel discrete events-based simulation method was used to calculate project period under the condition of activity relationships and rework, and the calculated results of project period distribution were helpful to decide reasonable project period. Finally, a case study was introduced to demonstrate the application of the proposed model.
