Research On The Project Management Of The Overhaul Period In The New Coal Chemical Industry Of A Company

The competition between the foreign and domestic coal chemical industry become extremely fierce during the past two years,due to the fact of the decrease of international price of crude oil and the excessive domestic chemical production that cause the even lower price of the products as well as the serious reduction of corporate profit.For the sake of enhancement of the enterprise competitiveness,many coal chemical enterprises try to explore the strategy to extending the overhaul period of coal chemistry in order to shorten the period and thus reduce the costing of the overhaul.The company A is a kind of new coal chemistry production manufacture producing methanol,acetic acid,acetic ether based on coal.As an exemplary coal chemistry manufacture,the main strategy is to promote the whole company by ensuring the quality and safety,reducing the shutdown overhaul time in order to facing the fierce competition problem.The work here stated the background and the aim of shutdown overhaul period in the new coal chemical industry based on the circumstance of company A,and analyzed the company A's project of shutdown overhaul,the main condition of overhaul,and the facing problems.Then the analysis will be carried out by the structural decomposition of the major repair project based on WBS,make sure the sequence and time parameter of each process,analysis,design of the network diagram.The time will be calculated by the Tri-point estimation,which can be accomplished by the earliest elapsed time,the earliest finish time,the longest start time,as well as the longest finish time.The critical path for the project can also be settled down and the safeguard measure for the process control is also put forward.Based on the above,the method for how to plan and control the quality of the project is discussed and the aims and safety measures are discussed in detail.
