Research The CPM In The Construction Progress Control Of CSG Steel Rolling Project

Iron and steel industry as an important pillar industry of national economy, is taking along time simply by expanding the capacity of the extensive development of the road,especially in the second half of2008,"financial crisis" industry contradictions and problemsof sustainable development. At present, Shaoguan Iron&Steel only platform with the annualoutput of500tons of steel capacity, smaller, very much as an ordinary bar products, wireproducts, high cost, low-grade, the structure is irrational, weak competitiveness. Survival anddevelopment from the perspective of Shaoguan Steel to build steel mill project to adjust theproduct structure upgrading without delay. CSG has a large steel mill project moreindependent, complex engineering structures and construction technology, investment capitaland construction risks, construction of units, long construction period, the characteristics ofhigh quality, project management as a key part of the progress and an important part of the notonly closely related with the project cost, but also directly affect the project’s success orfailure of the entire project management a top priority. In this context we use the progress ofthe project under the management of advanced theory of CSG steel rolling project the projectobjectives, determine the critical path and critical path optimization studies.Background research through the project, pointed out that implementation of the CSGsteel rolling project of the necessity and urgency of the mainresearch contents and methods;control the use of project-based construction organization CSG steel rolling projectconstruction schedule; according to CSG steel rolling project schedule management process,from the owners, design, equipment, materials, construction teams, supervision, and social,political, weather, natural disasters and other aspects of the factors that affect the constructionschedule for in-depth discussion and analysis; described CSG steel rolling control the contentsof the project construction schedule, list the construction progress control of the basicprocesses and major construction management, construction processes; scientificdevelopment of the CSG flexible steel rolling project schedule, target management withdynamic adjustment of the schedule objectives; of CSG steel rolling project constructionprogress control of the network structure were analyzed and discussed, the CSG steel rollingproject work breakdown structure (WBS) for a detailed breakdown, milestone planning andconstruction of the development of network planning; CSG steel rolling project schedule forthe control of key nodes in-depth analysis to determine the CSG steel mill project critical pathand the total duration of construction; a detailed analysis of steel rolling CSG operations research project critical path characteristics, characteristics of the critical path based on thisconstruction project milestone means to optimize the use of resources; characteristics inoperations research, based on the steel to build CSG rolling project schedule controlmathematical model and optimization from the progress of the project, progress-andprogress to optimize resources-financial optimization model to optimize the three aspects.Finally, the application of the model and operational recommendations were discussed.CSG rolled steel construction phase of the project schedule control studies, mainly usinga combination of theory and practice, systems analysis, specification analysis and analytichierarchy process, focusing on the specific practice guidance and applied the proposedmethod and means to have a more strong practicality. This has a distinct target, not only in theCSG steel rolling project construction has been a good application, but also for the futureconstruction of similar large-scale industry has a strong role in guiding and learn.
