Abstract:From the viewpoint of the fourth party logistics routing problem(4PLRP) and the cost discount factor in the
transportation, a multi-task 4PLRP with cost discount is modeled. Considering the 4PLRP’s chosen process coincided with
the third party logistics’ selection, an ant colony algorithm and an ant colony algorithm with dynamic transition probability
are respectively used to solve the problem. Experimental results show the effectiveness of the proposed algorithms.
