Research on Optimization of Outfitting Inbound Logistics Path Based on Milk-run
The way that the shipyard organizes vehicles to carry out milk run was put forward to opti-mize the route,and the model and solution were based on mixed integer programming and actual situa-tion.Considering the complexity of outfitting types and palletized logistics organization,the con-straints of demand splitting,multi-vehicle,multi-product and mixed time window were added.Ac-cording to the supplier's production,loading and unloading capacity and time window range,the pick-ing quantity was dynamically adjusted to improve the picking efficiency.Taking the actual data of a shipyard in Shanghai as an example,Matlab was used to call Gurobi solver for calculation.The results show that the milk run can reduce the inventory cost by 28.09%and the transportation cost by 4.38%,and improve the lean level of goods delivery.
