[0079] (Measured value of dock height at operation stage α - reference value of settlement at operation stage α) - (Measured value of dock height at operation stage β - reference value of settlement at operation stage β).

[0080] For example: the operation object is the stern half of the ship; the operation stages are full docking and before floating. As shown in Table 6 below, the settlement of dock 1 = 15mm, and the settlement of dock 2 = 10mm.

[0081] Table 6

[0082]

[0083] S6: Analyze the matching degree of the dock piers, set a matching degree reference value for each operation object, and calculate the matching degree of each dock pier of two different operation objects in the same operation stage.

[0084] Specifically, a matching degree reference value for each operation object is set, and the matching degree of each dock pier of two different operation objects in the same operation stage is calculated.

[0085] Calculation rules for dock pier matching degree:

[0086] (Measured value of dock height of working object α - reference value of matching degree of working object α) - (Measured value of dock height of working object β - reference value of matching degree of working object β).

[0087] For example: the operation stage is before floating; the operation objects are the stern half ship and the whole ship, as shown in Table 7 below, the matching degree of dock pier 1 = 15 mm, and the matching degree of dock pier 2 = 10 mm.
