PFDA- FMEA. An Integrated Method Improving FMEA Assessment in Product Design

Abstract

Product Design is getting nowadays new challenges on developing new products, since the industry is in a rush to introduce products into the marketplace, where customers demand products faster, cheaper, and free of failures. In the meantime, global companies are always trying to improve their Product Design process to get advantages over their competitors using proven tools like FEMA and mixing methodologies like Fuzzy theories with FMEA. Even today using all this tools and combination of methodologies there is a gap to address and it is required a robust risk analysis solving current issues in the electronic industry. This document aims to reveal a novel integrated method, where Failure Mode and Effect Analysis, Pythagorean Fuzzy Sets and Dimensional Analysis are cohesive into a model that minimize the uncertainty of the ranking and prioritization over the Failure Mode and Effect Analysis execution, helping to identify risks within an accurate grade over possible failures in the Product Design process. A real practical example is used to show the proposed method, where it is identified a robust methodology integration and solid and results using a sensitivity analysis.

PFDA-FMEA-VSM Application for Outsourcing Risk Analysis

“…FMEA is as well a common tool use during the OP [6], however, FMEA is adding uncertainty to the RA since the intervention of the human final decision on what are the risks [7], [8]. Additionally, different studies are showing how to remove the uncertainty while using the FMEA combining Multicriteria methods [9], [10], [11], [12], [13]. Furthermore, Pythagorean Fuzzy Dimensional Analysis -FMEA-Value Stream Mapping (PFDA-FMEA-VSM) [14], is a proved method to remove the uncertainty during the RA.…”

Risk Assessment With Value Added Pythagorean Fuzzy Failure Mode and Effect Analysis for Stakeholders

“…Thus, the current RA tools are not enough to cover the identified gaps over the NPDP-RA, in the first instance because of the uncertainty while the assessment is usually slanted by human decisions. The PFDA-FMEA proposed method [28] removes the uncertainty induced by the human factor during the RA using FMEA in NPDP. Another gap in the NPDP-RA, is the use of the tools focused on a single phase of the NPDP at a time, to cover this gap, another contribution in this paper is the integration of VSM, attaining the value added through the NPDP.…”

“…Therefore, the novel proposed method PFDA-FMEA-VSM for stakeholders is presented within the integration of the PFDA-FMEA proven method [28], then adapting VSM. Likewise, PFDA-FMEA-VSM integration will help NPD project stakeholders to have an effective assessment based on their main project objectives.…”
