PFDA-FMEA, an Integrated Method Improving FMEA Assessment in Product Design
Resumen
Product Design (PD) currently faces challenges in new product development, since the
industry is in a rush to introduce new products into the market, with customers demanding products
that are faster, cheaper, and free from failure. In addition, global companies are trying to improve
their product design risk assessment process to gain advantages over competitors, using proven
tools like Failure Mode and Effect Analysis (FMEA) and mixing risk assessment methods. However,
with current risks assessment tools and a combination of other methods, there is the opportunity
to improve risk analysis. This document aims to reveal a novel integrated method, where FMEA,
Pythagorean Fuzzy Sets (PFS), and Dimensional Analysis (DA) are cohesive in one model. The
proposed method provides an effective technique to identify risks and remove uncertainty and
vagueness of human intervention during risk assessment using the Failure Mode and Effect Analysis
method. A real-life problem was carried out to illustrate the proposed method. Finally, the study was
substantiated by using a correlation and sensitivity analysis, demonstrating the presented integrated
method’s usefulness in decision-making and problem-solving
