Research On Optimal Management Of Project Schedule For Equipment Maintenance In Continuous Manufacturing Enterprises

A Natural Gas Purification Plant is an important refining and chemical production base in Western China.It is also a large-scale comprehensive refining and chemical enterprise.It has complete refining and chemical equipment,so its energy strategic position is very prominent.The biggest characteristic of refining and chemical enterprises is continuous production,which is also the first condition for enterprises to create profits.This can stand out in the strong market competition and occupy a certain position.However,with the development of continuous production,more and more problems have gradually emerged,and various constraints have been exposed,thus affecting the development of refineries.In order to promote the stable development of A natural gas purification plant,it has become an important annual task for A natural gas purification plant to carry out plant shutdown and maintenance work.In the management and operation of the company,the overhaul project is the most important work,so we need to arrange the overhaul time and project reasonably,so as to generate revenue as soon as possible.In recent years,enterprises have gradually realized the importance of maintenance work and began to improve maintenance management projects.From planned maintenance at the beginning to preventive maintenance at the later stage,to predictive maintenance at present,schedule management is always running through the overall process of maintenance project management.It can be concluded that the study of maintenance schedule has important significance and role.Firstly,this paper makes a detailed analysis of the influencing factors of equipment overhaul in Company A,and then introduces the planning of equipment shutdown overhaul project in purification plant A.It mainly expounds the relationship among the three functions of organization,planning and control in annual overhaul project management,and comprehensively analyses the schedule influencing equipment overhaul.The factors of planning.According to the research,it can be concluded that there are still big problems in the preparation of equipment maintenance schedule,which need continuous improvement,such as lack of floating time in the preparation process,single method and unreasonable consideration of quality problems in the operation process.Aiming at the problems mentioned above,the main reasons are analyzed,and the solutions are put forward.The Gantt chart and the initial network plan are designed.By comparing and analyzing,the best scheme is selected,so as to carry out in-depth exploration.At the end of the paper,the possible problems are analyzed,and the corresponding solutions are put forward to ensure the smooth development of the overhaul project.Because the overhaul of the natural gas purification plant has the characteristics of universality,the content of this paper is also universally applicable and extensive.
