Study of Using Critical Path Method to Formulate the Algorithm of Software Project Schedule Planning

Formulating the practical schedule planning for the software project, is the basis of orderly carrying out the software project, is the key of project to success. In this paper, study the application of using the critical path method and related technologies to formulate the computer program algorithm for the software project schedule planning. First of all, to clarify the basis preparations, including determine the project scope, definition activities, activity sequencing, activity duration estimation, etc, Secondly, to derive the critical path, including calculate the active time, determine the critical path, then study the Software algorithm, including database design and use the problem analysis diagram to show the core program algorithm, finally, using the program, which is written in accordance with the algorithm, to simulate project plan instance, and according to the simulate result, for the specific management. The results show that, using the computer software programs to achieve the critical path method and the related techniques to formulate the schedule, to reduce the workload of plan formulation, improve the accuracy of the plan, has the higher theoretical and practical value.
