Research on Software Project Schedule Planning Technology Based on the Integration of PERT and CPM

Make a feasible schedule planning for software project, is the foundation to carry out an orderly software project activity, is the key to success of the project. To solve the difficulties of schedule planning, this article studies the science technology and methods, including four aspects: First, using network chart to show the dependencies between activities, including Precedence Diagram Method and Arrow Diagram Method; Second, Program Evaluation and Review Technique is used to evaluate the time of the project activity; Third, the critical path method of determining the project total duration, including deduce from calculation formula of active time and determine the critical path; Fourth, duration compression method based on progress compression factor method. According to the situation of many technologies and methods, studied the main factors considered by selecting techniques and methods. Results show that using scientific technology and method to make the schedule planning, will reduce the workload of planning, improve the accuracy of the plan and have high practical value.
