B. Mining Company Evaluation By Using DSS Tool

This is the last step of mining company evaluation processes. Report that has been scored by the user evaluator will be processed in DSS tool. The first step of this evaluation process is to derive weight for each Good Mining Practice component.

User government officer defines the degree of importance of each component by asking how important is one component compared to another component. The degree of importance is presented in a range value from 1 to 9. Figure 4.22 AHP Form After the pair wise matrix has been filled, the software will calculate the weight for each component. To indicate whether the value inputted by the user is consistent, we need a consistency indicator called Consistency Ratio CR. The value inputted by the user is considered as consistent if the CR less than 0.1 70 Figure 4.23 Result of AHP Process The weight derived from this process can be saved into the database to be used in second step of mining company evaluation.
