Overall Scores and Ranking of Preliminary Selection of Biodiesel Raw Material
After statistics processing, the scores and ranking of the ten biodiesel raw material
plants are presented in Table 4.5.
Evaluation of General Functions and Secondary Selection
In terms of national development, biodiesel development is a massive systematic
project. Its contributing factors are so complicated that they require strict, welldesigned economic evaluation. To determine or optimize the technical projects, we
cannot be satiated with the evaluation of a single technical indicator or economic
indicator. Instead, multiple contributing factors should be analyzed and examined.
That is, a scientific examination method and a quantity standard should be established
to provide objective, accurate, and reliable evaluation.
