A new chemically disposable screen-printed modified electrode with yttrium doped manganese oxide (Mn2O3/Y2O3) nanocomposite at screen printed electrode was mainly constructed to quantify xylometazoline hydrochloride (XMZ). The crystallographic parameters were estimated from the XRD spectrum, suggesting that Mn2O3 of cubic phase with average grain size similar to 77 nm. The SEM images revealed that Y3+ dopants had improved the surface topology. The findings indicate that morphological features play a vital role in improving the electronic properties of the fabricated electrode. Augmentation of Six Sigma (SS) with molecular dynamics simulation (MD) as a theoretical study was widely adopted to improve the current process as a quality management methodology by measuring the process capability to determine if the process meets the desired specification limits. Process capability is determined through measuring the variability in the process output and comparing these variations with the desired specifications. Also, it assures a robust method specification at a high level of targeted performance and statistical confidence. A greenness assessment procedure utilizing the eco-scale algorism was conducted to prove the greenness of the proposed methodology. Additionally, the proposed sensor presented a high sensitivity over the concentration range (1x10(-6)-1x10(-2) mol L-1) of a detection limit 3.93 x 10(-7) mol L-1 with the Nernstian cationic slope of 58.18 +/- 0.76 mV decade 1 at 25 +/- 1 degrees C.
