A record-to-record travel algorithm for the integrated order picking-vehicle routing problem in a B2C e-commerce context

Abstract

In B2C e-commerce sales, customers expect a fast and low-cost delivery. To be able to fulfil these expectations, both warehouse and distribution operations have to be performed carefully. Ideally, these two supply chain functions should be considered simultaneously in an integrated problem. In this presentation, a record-to-record travel algorithm using local search operators is developed to solve this integrated order picking-vehicle routing problem (I-OP-VRP). Experiments reveal that high-quality solutions can be found in small computational time.
