On the Use of Corrective Maintenance Data for Performance Analysis of Preventively Maintained Textile Industry

In this paper, a method is proposed to improve the scheduled preventive maintenance of the system by assessing different kinds of availability and illustrated how the corrective maintenance data can be helpful to reschedule preventively maintained system. This method uses the concept of inherent availability to ensure to what extent maximum availability can be extended. The application of the proposed methodology has finally been demonstrated to six unit textile weaving industry situated in northern India. A mathematical formulation of Chapman – Kolmogorov differential difference equations, determining its availability, has been developed. A numerical study has been carried forward to quickly analyze the availability of the system on the actual corrective maintenance data taken from this industry.
