Software process deviation control based on system dynamics

To quantitatively control software processes and resolve the lag effect problem,a method of deviation threshold calculation is put forward.Based on system dynamics,deviation control and software process is analyzed by setting project progress rate as the goal under control and adding manpower as repairing action.And a software process model is constructed.Then automatic simulation process is established by adopting dichotomy algorithm and the control threshold is calculated to support process control.Finally,a case study is presented to valiate the model verify the feasibility of the method.
