Intuitionistic fuzzy REBA method and its application in a manufacturing company
Erginel, Nihal; Toptanci, S. (Springer Verlag, 2019)Work-related musculoskeletal disorders (WMSDs) are a major health problem. Many methods have been developed for assessing the risk level of work for WMSDs. Rapid Entire Body Assessment (REBA) method is one of the most ... -
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 ... -
Optimization of bio-oil production using response surface methodology and formation of polycyclic aromatic hydrocarbons (PAHs) at elevated pressures
Ateş, Funda; Erginel, Nihal (Elsevier Science BV, 2016)This paper aims at the optimization of bio-oil yield obtained from poplar sawdust pyrolysis. A response surface methodology was carried out to optimize the experimental conditions. The factors investigated were temperature, ... -
