Abstract As to the practical complex logistics distribution situation that the distribution task cannot be completed in time, which brings tardiness risk and loss for company, the routing optimization problem in the fourth party logistics with consideration of tardiness risk is studied. A mathematical model minimizing tardiness risk and taking the distribution costs as constraint is set up, using Value-at-Risk to measure time risk. A deletion algorithm embedded harmony search is proposed considering nonlinear and NP-Hard characteristic of the problem. The effectiveness of model and algorithm is verified through solving the different scales of cases.
