SYSTEM, METHOD AND PROGRAM PRODUCT FOR PREDICTING FLEET RELIABILITY AND MAINTAINING A FLEET OF VEHICLES
First Claim
1. A method of maintaining fleet performance for a fleet of platforms, said method comprising the steps of:
- a) querying a platform maintenance database for part removal data of parts in each platform;
b) performing Weibull analysis on said part removal data;
c) generating a risk report indicating platforms having a probability of failure above a selected threshold in a selected time window; and
d) generating an inventory risk report indicating current inventory exposures.

Abstract
A system, method and program product for maintaining fleet performance for a fleet of platforms, especially for a fleet of aircraft. Part removal data is contained in a maintenance database. A query is constructed for extracting part removal data from the maintenance database. Weibull analysis is applied to extracted part removal data. Exposed aircraft with parts being likely to fail within a given time period are identified from the Weibull analysis results. Overall part failure numbers are generated for each failing part. Inventory is checked to determine if sufficient spares are available to repair all expected failures. Any shortfalls may be covered. A risk report is generated for the fleet and for inventory. Each risk report highlights likely problems that may require immediate attention.
