Table 9: Definition of the numerical score for the criteria and result of the weights. When the instrument score by measurement is defined, the ranking of the instruments is obtained. The instrument ranking (Table 12) is computed as:  
\[Ranking_{instrument}=\sum_{i}^{n}(instrument_{score-by-measurement*W_{i}}). \tag{4}\] \begin{table}
