Subway vehicle maintenance material quota management method

Abstract

The invention discloses a subway vehicle maintenance material quota management method, which comprises the steps of determining and decomposing a vehicle maintenance operation task, forming overhauling working procedure unit modules, and defining the measurement unit and step pitch of each overhauling working procedure unit module; planning based on the current overhauling engineering quota data,forming three types of original data groups, recording an original sample of an actual measurement project, and carrying out data deviation analysis; measuring and calculating the project quota according to historical data, and adjusting the project quota according to variations in operation task property; forming a maintenance material quota evaluation system by taking the project as a unit, andcarrying out rationality verification; and predicting a maintenance material quantity index according to a periodic overhauling task. By adopting the technical scheme disclosed by the invention, the vehicle maintenance material quota can be quantitatively evaluated and predicted according to the average advanced level principle, a subway operating unit is guided to improve the existing maintenancetechnology, the cost is reduced, and the benefit is increased.

Description

technical field [0001] The invention belongs to the technical field of subway maintenance management, and relates to a management method for quota management of subway vehicle maintenance materials. Background technique [0002] The rapid, efficient, and comfortable operation and service advantages of the subway determine its financial characteristics of high investment scale and high operation and maintenance costs. Controlling maintenance costs and improving resource utilization efficiency through quota management is an important maintenance management link for subway operation and management enterprises. [0003] The subway vehicle system is complex, the technical requirements are high, and its maintenance management content is complex and the process is complex. Metro maintenance usually includes regular planned preventive maintenance, maintenance after vehicle failure, etc. The maintenance content is cross-cutting, and there are many types of materials and spare parts r...

Problems solved by technology

[0003] The subway vehicle system is complex, the technical requirements are high, and its maintenance management content is complex and the process is complex. Metro maintenance usually includes regular planned preventive maintenance, maintenance after vehicle failure, etc. The maintenance content is cross-cutting, and there are many types of materials and spare parts required for maintenance. Operation organization tougher

Maintenance is affected by uncertain factors such as operating environment, staffing, resource reserve, repair schedule and system, lack of systematic maintenance consumption management

[0004] Traditional maintenance consumption statistics and management are completed by manual records. The maintenance records are rough and the statistical dimension is not fine enough to realize the consumption statistics and quantitative management of the corresponding process.

The management of maintenance costs stays in the annual or monthly maintenance cost management, and the assessment of single equipment, process consumption, and maintenance standard costs is weak, and it is impossible to finely manage and control maintenance materials
