Abstract: Based on a large amount of orders picking, orders’ strong personalization, batch delivery and shorter time, this paper proposes that batch delivery should be considered while order picking. According to ‘Similar orders should be group picked’, introducing group production ideas, picking sequence optimization model considering batch delivery is established. Aiming at this model’s characteristics, such as multi-stage decision, multi-variable, and NP-hard, based on reverse sequential decision method, a sequential solution method is put forward, and the algorithms of each stages are presented. Finally, the application examples are conducted to verify the feasibility and effectiveness of the model and algorithm. The results show that, order picking considering batch delivery together saves more picking costs than considering delivery independently and non-group order picking which could serve as a theoretical guideline for order picking planning of enterprises selling fruits and vegetables online.
