Research On The Application Of Time Management In JZ Company R Project Construction

JZ Company is one of large key companies for national military products manufacture and undertakes the tasks of scientific research and development, production and operation of national high-tech military products, which make positive contributions to modernizing national defense. Since the 12 ^th Five-Year Plan, JZ Company undertakes the organizational performance and management of various types of investment projects for fixed assets including research and production security, key basic products, energy saving and emission reduction and lot production construction. Its project number is nearly triple of that in the 11 ^th Five-Year Plan. However, JZ Company hasn’t update its project management modes, which results in the traditional manual management mode always induces the project not to be controlled, and the situation that the project is slack at the beginning and have to speed up towards the end and cannot be finished in time occurs. Such problems seriously conflict with the policy background that the management system for the current national investment projects of fixed assets is more and more perfect and the requirement on project period is higher and higher. The scheduling problems in R project of JZ Company urgently need to be addressed.R project of JZ Company is an investment project of fixed assets for science and technology industry of national defense, which has been approved by State Administration of Science, Technology and Industry for National Defense in 2015. The project investment is characteristic of large scale, complex construction and higher scheduling requirement, and hence, how to conduct time management and control schedule scientifically in R project urgently needs to be solved. This paper tries to apply project time management method to control the time management mode and schedule control measures in R project.This paper firstly introduces the current situation of project time management in domestic and foreign theories and application, analyzes the problems in management process, construction system limitation and the control of time management and schedule control in R project. The author applies advanced time management theories such as WBS task decomposition, milestone determination, critical chain method and critical path method, defines 36 sub-activities in R project, orders the sub-activities by precedence diagramming method and estimates activity resources and activity duration to solve the problems in R project including one-side scheme, mere formality, rough planning and lack of overmeasure; meanwhile, the author combines professional software to set up and optimistically adjust the scheduled plan of R project, shortens the construction period of R project by shortening construction period of key path by 9 months, to wit: 28% of construction time has been shortened, which satisfies the requirement of project period and leaves one-month butter time for uncertain factors during R project construction such as plan change.In scheduling control, the author combines modern scheduling management theories and specific condition of JZ Company to propose 7 change methods for its scheduling control and set up perfect scheduling control system and procedures, which solves the problems including schedule delay, rough adjustment and changes of schedules well, and the schedule of R project is controlled.
