For table b, coverage 90 is in the range of 1-500, which corresponds to a weight of 20%, with a score of 15 × 20% — 3; the blood margin is a settlement system, the corresponding weight of the settlement system is 30%, and the score of the blood margin is 30 x 30% ═ 9; the heat degree range of the heat degree 600 is 501-10000, the corresponding weight of the range is 50%, and the score of the heat degree is 15 × 50% — 7.5; the hierarchy is B3, the weight corresponding to B3 is 60%, and the score of the hierarchy is 20 × 60% — 12; the subject is settlement, the index weight is inquired, the range where settlement is located is determined to be a settlement system, the weight corresponding to the settlement system is obtained to be 30%, the score of the subject is 20 × 30% equals6, the sum of the score 3 of the coverage degree, the score 9 of the blood margin, the score 7.5 of the heat degree, the score 12 of the hierarchy and the score 6 of the subject is calculated, and the index caliber score corresponding to the table b is obtained to be 37.5.
Since the index caliber score corresponding to table a is greater than the index caliber score corresponding to table b, the index caliber corresponding to table a is taken as the standard caliber of the index "selling price".
