Research On The Project Schedule Control Of Ningxia Petrochemical Instrument Maintenance

The instrument maintenance of the ningxia petrochemical,due to specificity,complexity,large-scale,long in period,multiple processes of the instrument maintenance,every year there have some problem about some maintenance project overhaul period extend and maintenance funds beyond the budget in the work of power plant maintenance and overhaul.But seriously affected the normal product of ningxia petrochemical.How to reduce the cost,high reliability of equipment,reduce equipment manintenance is a problem of ningxia petrochemical need to face and to resolve.This paper with the ningxia petrochemical instrument maintenance schedule control as the main line,system research the ningxia petrochemical instrument maintenance schedule control.This paper first describes the general theory of project management,;then analysis the process and status of instrument maintenance project management about ningxia petrochemical,find out characteristics of the instrument maintenance project,find influence factors of instrument maintenance project schedule;third application method and theory of project management schedule planning and control,to organization and optimization the schedule planning and network diagram of ningxia petrochemical instrument maintenance.The fourth find out the key path and the key node,omnibearing schedule control research to optimized schedule planning;last in the end of each section propose specific countermeasures of the ningxia petrochemical instrument maintenance project schedule planning.Accroding to above research and analysis result,to research the schedule planning of ningxia petrochemical instrument maintenance project in 2015 years,reached shorten the period of maintenance?decreased the funds budget of the maintenance,guaranteed quality and quantity to complete the task.Show this rearch have certain application value.
