Abstract Applying risk assessment approaches to improve quality in enterprises is of great importance especially for sectors that are labor-intensive and thus frequently encountered failures. One the methods used take precautions against failures caused by high variability this type sector failure mode effects analysis (FMEA). In study, a hybrid FMEA approach proposed so as measures textile whe...
