The invention relates to a parking group inducing method and a parking group inducing device, wherein the method comprises the steps of determining alternative parking lots of a user in a target area, and obtaining an evaluation
score according to an
evaluation function of the alternative
parking lot relative to a corresponding user; constructing a weighted
bipartite graph G=(X,Y,W) with limited node capacity according to the alternative parking lots and the evaluation scores; extending the weighted
bipartite graph G=(X,Y,W) with the limited node capacity, and obtaining a weighted
bipartite graph G'=(X,Y,W,S,E,SY,EY,SW,EX) with weights of a function relation; calculating a network
maximal flow from a node S to a node E in the weighted bipartite graph G'=(X,Y,W,S,E,SY,EY,SW,EX) with weights of the function relation, and simultaneously recording a matching relationship between the user and the
parking lot on the condition that the network
maximal flow is formed; and pushing a corresponding
parking lot to the user according to the matching relationship between the user and the parking lot on the condition that the network
maximal flow is formed.
