Abstract:Based on the background of fresh products distribution,this paper analyzes the literature on fresh product distribution and vehicle routing problem with time windows in recent years. Based on the vehicle routing problem with time windows,a mathematical model to minimize the vehicle driving cost is constructed and solved by the branch and bound algorithm in CPLEX solver. Compared with the known optimal solution and other literatures,the results show that the branch and bound algorithm is feasible and superior in solving the fresh product distribution problem with time window vehicle routing.
Keywords:traffic engineering;vehicle routing problem with time window;fresh product;CPLEX;branch and bound algorithms
