Client's Needs

Increasing failure incidents observed - As most Screen Doors have been installed for more than ten years, increasing failure incidents were observed by maintenance team.

Our Solutions

A numerical life data analysis was conducted based on the field failure data provided by Client. The probability of failures, the predicted number of failures and the remaining life of the two most critical components of the system were estimated. Overhaul replacement cost and corrective maintenance cost for coming few years were estimated for the client. Client was able to develop a maintenance strategy based on the calculated data.
