FMEA with similar products or processes; hence enabling

FMEA is a popular and practical quality and risk
assessment tool. It is useful to define, identify, and eliminate known and/or
potential failures, problems, errors from a system, design, process, and/or
service 2. Failure mode means the way or modes that can cause fail and error
in the process or system 3. Effect analysis means study or analyse the
failures occurred in the operations. The purpose of the FMEA used
is to eliminate or reduce failures, starting with the highest-priority ones. A
successful FMEA implementation helps the manufacturing team to identify
potential failure modes based on their past experience with similar products or
processes; hence enabling the team to eliminate or reduce system failures with
the minimum effort and resource expenditure. In FMEA, RPN (Risk priority
Number) is obtained by multiplying three risk factor which are severity (S),
Occurrence (O) and Detection (D), RPN=S x
D x O, where O and S are the frequency and seriousness (effects) of the
failure, and D is the ability to detect the failure before it reaches the
customer. As an alternative, the FIS-based RPN model
3456 uses an FIS model to aggregate these three risk factors, and
produces a fuzzy RPN (FRPN) score, FRPN=fRPN
(S,O,D). Potential failure modes and their S, O, and D ratings are firstly
determined. The FIS-based model has several advantages. These include (i) the FIS-based
model allows the modeling of nonlinear relationships between the RPN score and
the three risk factors; (ii) it is robust against uncertainty and vagueness; and
(iii) the scales of the attribute(s) can be qualitative, instead of
quantitative 7. This research is important because it contributes towards
improving the quality and production of wood. Besides, this study establishes
an effective management for wood production. Real data/information gathered
