The design of the experiment (DOE) was generated according to the Taguchi L9 (3^4) array. DOE varied four factors on three levels. The general plan contains a set of seven experiments, which correspond to seven temperatures in the range from -20 to +40 °C. Key factors were the number of smoke grenades, humidity (g/m^3), pressure (kPa) and wind speed (m/s). Kolesnyk, Vitalii(Sumy State University)
