Research On The Critical Chain Project Schedule Risk Control By Immunization

The rapid development of information technology has led to an era of time-based competition, making the project schedule management particularly important in the field of project management, thus gave birth to Critical Chain Project Management and other project progress network planning techniques. However, in this era of time-based competition, the projects are facing more risks. Many project schedules that are constructed in determinate environments gradually show their shortcomings in dynamic environments, many of the project schedules delay because of the influence of risks, and even ultimately lead to project failure. Therefore, analyze the progress of a project, control the risk of progress effectively, and finally ensuring the smooth implementation of the project schedule has become the key to the project schedule management and focus of research.The paper studies excellent mechanisms in the field of biological immunity and artificial immune system that can be used as a source of reference in project schedule risk management. On the basis of a comparative analysis of the similarities between biological risk management and project schedule risk management, the paper proposes introducing the idea of immune to the project schedule risk management and the concept of project schedule risk immune, and build up the immune system for the project schedule risk. On this basis, the paper studies immune-based Critical Chain project schedule risk control mechanism, then studies the three key technologies, which are the buffer setting of the Critical Chain, the vaccination of the key risks, and the mechanism of the risk study and memory. Lastly, the three key technologies are achieved by a procedure compiled with VC++ language.The paper constructs a project schedule risk immune system and achieves improvements of the Critical Chain project schedule risk control technology on the basis of introduction of immune-related ideas, It is a beneficial exploration in applying immunization to the field of project schedule risk management. The research results enriched the content of project risk management to certain extent; and also have a certain degree of practical significance in cognition schedule risk, effective management of project schedule risk and the maintenance of project progress and stability.
