摘要：

A theoretical model was presented for quickly identifying multiple indoor constant contaminant sources with known releasing time by considering the sensor thresholds and measurement errors. The model was numerically demonstrated and validated by case studies. The results indicated that the model can potentially be effective with high sensor thresholds and measurement errors. This study will contribute to developing source identification techniques using real sensors.
