Estimating Fuzzy Life Time with a Fuzzy Reliability Function in the Appliance Sector

Erginel, Nihal; Saraçoğlu, Hande; Yıldız, Gülay; Şentürk, Sevil (Springer International Publishing Ag, 2018)

Reliability is defined as the length of time a component works without failing. The reliability function shows an estimate for the probable amount of time a component should work without experiencing failure. Fuzzy set ...
Modeling attribute control charts by interval type-2 fuzzy sets

Erginel, Nihal; Şentürk, Sevil; Yıldız, Gülay (Springer, 2018)

Fuzzy attribute control charts, where data are classified into conforming/nonconforming product units, are used to monitor fuzzy fractions of nonconforming units for variable sample sizes and the fuzzy number of nonconforming ...
Monitoring Fraction Nonconforming in Process with Interval Type-2 Fuzzy Control Chart

Erginel, Nihal; Şentürk, Sevil; Yıldız, Gülay (Springer International Publishing Ag, 2018)

Fuzzy set theory is particularly appropriate approach when data include imprecise. Type-2 fuzzy set theory captures ambiguity that associates the uncertainty of membership functions by incorporating footprints and models ...
