Method for continuously estimating persistent and intermittent failure probabilities for production resources

摘要

Production control systems and methods are presented for estimation of production resource failure probabilities in which set of four count values are maintained and updated for each resource including first count value m 11 indicating number of plans where the resource m was used and failed, second count value m 10 indicating number of plans where the resource m was used and succeeded, third count value m 01 indicating number of plans where the resource m was not used and failed, and fourth count value m 00 indicating number of plans where the resource m was not used and succeeded, and the current fault probability for each resource is estimated and stored for single or multiple, persistent or intermittent faults based on the corresponding count values.
