Functional analysis: an introduction to methodologies of reliability for mechanical systems

Both the market and the legislation impose strict requirements regarding quality, reliability and safety, making the management of the design phase ever more important. It must be organized with the aim of guaranteeing effectiveness, efficiency and completeness whilst also being precisely aligned to the requirements of the client. The aim of this work is to study and describe it rational technique of systematic analysis of the product which is inserted before the prevention activities for reliability. Starting from an analysis of reliability methodologies widely in use at the moment (e.g. FMEA), it is considered necessary to place Functional Analysis before the phase of optimizing reliability.
