Research on Location Selection of Pre-warehouses Based on Extended CFLP Model

Abstract The warehousing logistics mode of “pre-warehouse plus terminal distribution” is a decentralized resource allocation scheme around the industry at end distribution, supporting development New Retail, data-driven extensive retail form centered on consumer experience. Firstly, taking stand-alone pre-warehouse as research object, this paper analyzed distribution characteristics new fresh goods, consumption structure demand and functional pre-warehouse. Secondly, extended CFLP (Capacitated Facility Location Problem) model was established with processing fee, freshness loss, time penalty warehouse service capacity. In addition, one-to-one relationship between point storage facilities in traditional changed to many-to-many order improve overall facility utilization. Finally, an improved coding genetic algorithm adopted solve nonlinear mixed 0-1 programming model. Therefore, location, matching volume were showed same time. results example demonstrated that gave priority meet timeliness fully utilized
