  • 8. Research Methodology • Selection of Parameters • • The parameters were identified from literature. These parameters were then categorized into two category viz. economic parameters and technical parameters. • Survey Design • • • Questionnaire was designed for evaluation of different parameters. Structured questionnaires were prepared, tested, validated, modified and opinion was collected from experts through web base survey. The experts were asked to assign importance of the parameters on a 10 point qualitative linear scale. • Computational of weightage • Weighted average values have been computed for importance of parameters on 10 point scale.
