Abstract: The logistic distribution under electronic commerce environment has the character of dispersive customer positions, large order forms, little batches and many repeated routes. Traditional optimizing route methods meet with diversified problems at different levels and are difficult to play their roles. Therefore, according to the particularity of logistic distribution under electronic commerce environment, the improved two-phase algorithm is needed. The test proves the validity of this improved algorithm by examples.
