I. Introduction

Ensuring customer satisfaction in aerospace and aviation engineering demands products that maintain high value and perform reliably throughout their life cycle [1]. Achieving this standard necessitates minimizing parameter variation in manufacturing processes and the final product. Each component, from elementary parts to complex assemblies, must uphold exceptional quality standards, offering reliability and safety in use [2]. In the aerospace and aviation industry, the terms "quality," "reliability," and "safety" are often intertwined. However, they hold distinct meanings. While reliability refers to the product's capacity to operate under predetermined conditions for a set amount of time, quality refers to the product's ability to fulfill specified requirements. Essentially, reliability extends the concept of quality across time, defining the duration during which a product maintains its quality standards for expected usage. Moreover, reliability is pivotal in ensuring operational safety, often sharing analysis methods and requiring mutual input. Reliability analysis focuses on uncertainties surrounding failure occurrences, operational disturbances, and their implications [3], [4], [5]. Conversely, safety engineering aims to shield the product from accidental scenarios' uncertainties. Both disciplines delve into studying, characterizing, measuring, and analyzing failures and their consequences to enhance operational systems.
