SCORE CALCULATION  
Score  Description  
Domain (D) (n criteria)  Score (P) 
This is the sum of the scores obtained in the domain's n prioritisation criteria: P=c_{1}+c_{2}+...+c_{n}= Σc c= score for each prioritisation criterion (range 19) n= number of criteria The minimum score is n (1 point x n criteria) and the maximum score 9n (9 points x n criteria). 
Weighted score (P_{pd}) 
This is the total score for the domain (P), multiplied by the weight allocated to the domain (Weight) and divided by the maximum score for that domain (P_{max}). P_{pd}=P x Weight / P_{max} The maximum score obtainable is the value of the weight allocated to the domain (Weight) 

Weighted base100 score (P_{b100}) 
This is the transformation of the weighted score (P_{pd}) on a scale of 0 to 100. P_{b100}=((P_{pd}P_{pd min})/(P_{pd max}P_{pd min}))X100 P_{pd}=Weighted score obtained in the domain P_{pd min}= Minimum weighted score possible in the domain P_{pd max}= Maximum weighted score possible in the domain The minimum score obtainable is 0 and the maximum score 100 

Total score (PT) 
This is the sum of the scores obtained in N domains. PT=P_{1}+P_{2}+...+P_{N}=ΣP P= Score in each domain. N= Number of domains for assessing the technology 

Total weighted score (PT_{pd}) 
This is the sum of the weighted scores obtained in N domains PT_{pd}=P_{pd1}+P_{pd2}+...+P_{pdN}=ΣP_{pd} P_{pd}= Weighted score assigned to each domain N= Number of domains for assessing the technology 

Total weighted base100 score (PT_{b100}) 
This is the transformation of the total weighted score (PTpd) on a scale of 0 to 100. PT_{b100}=((PT_{pd}PT_{pd min})/(PT_{pd max}PT_{pd min}))X100 PT_{pd}= Total weighted score obtained PT_{pd min}= Total minimum weighted score PT_{pd max}= Total maximum weighted score The minimum score is 0 and the maximum score 100 This is the value used to compare the respective technologies and depict them graphically 

Figures for each domain 
The weighted base100 score (P_{b100}) is shown for each domain 

Technology comparison figures 
Two graphical representation options are given, namely: showing the total weighted base100 score (PT_{b100}) for each technology; and, plotting a cumulativescore figure, showing each domain's weight in its total weighted base100 score (PT_{b100}). 
The following table shows the value assumed by each variable in the obsolete technology tool.
