Abstract
The invention provides a multi-period upgrade scheduling method, including: setting a quantity of periods for optical fiber upgrade, and determining a maximum optical fiber length of upgrade in each period; randomly generating an upgrade scheduling sequence, and calculating a total upgrade gain of the sequence; randomly generating a new upgrade scheduling sequence, and calculating a total upgrade gain of the current sequence; calculating a difference obtained by subtracting a gain of the previous sequence from a gain of the current sequence, if the difference is greater than or equal to 0, replacing the previous upgrade scheduling sequence with the current upgrade scheduling sequence, and if the difference is less than 0, accepting the current upgrade scheduling sequence according to a probability value formula; and performing multiple iterations, and if a new upgrade scheduling sequence has not been updated when a set quantity of iterations is reached, terminating iteration.
