자원 제약을 고려한 일정 문제 - 활동 진행중 재작업이 가능한 경우 -

초록

Activity requires to be performed again given the performance of project. This repetition of work is called rework. It is previously considered to occur upon completion of activity; however, due to the fact that changes in requirements in the project cause the occurrence time of rework vary from the beginning to the end. Thus, model and algorism to apply for the activity need to be developed. In this research, among SRCPSP (Stochastic Resource Constrained Project Scheduling Problem), statistical model of RCPSP (Resource Constrained Project Scheduling Problem) typical project scheduling problem, the method which when the period of activity acts as probability variable, expected value and multiplier of the unexpected value is used for estimation. Along with the method, a mathematical model, which shows rework can occur at arbitrary point, is developed and has proven its validity through simulated tests with applicable algorism. This research is significant because of extended experimental period of activity from the beginning to the end along with the distinguished means of the mathematical model which the period of rework is estimated via the expected value and multiplier of the value.
