Abstract

The fast development of e-commerce and higher customer expectations for quicker order delivery emphasise the importance of efficient management in urban warehouses, which operate in a setting with dynamic order patterns and stringent order lead time. Dynamic order-picking strategies became increasingly important as they allow for the dynamic assigning of incoming orders to pickers during each pick cycle. Collaborating with an industrial partner that develops cutting-edge Internet-of-Things technologies and platforms for smart warehousing, our proposed model extends the original dynamic order-picking problem by considering the due date and the order priority. Given the set of pickers and the sets of continuously coming new orders, our model focuses on assigning incoming orders to pickers and redesigning the routes of each picker on the sequence of item locations they will visit and the depot they will return to while meeting the time frame requirements for each order and considering the order priority in order to ensure a more efficient order-picking process in smart warehouses. Due to the time constraints and the need for quick response to the complex order fulfilment processes, the efficiency of the algorithm is as important as the solution quality. We propose a problem-tailored heuristic solution approach by extending the well-known heuristics, which can efficiently deal with the decisions of picklist updating, picker assignment, and rerouting.
