The Use of Control Charts To Monitor Air Plane Accidents of the Hellenic Air Force

Abstract

Accidents are unfortunate events that cause economic and/or human losses to individuals, organisations, companies or to the society. Air plane accidents cause both economic and human losses most of the times. In this paper we model the occurrences of air plane accidents using the Poisson distribution. We use control charts, which is the main tool of Statistical Process Control, to identify an out of control situation in the occurrence of air plane accidents. We propose the use of Shewhart and Exponentially Weighted Moving Average control charts and we apply them in real data from the Hellenic Air Force.
