WebApr 3, 2024 · Warehouses are nowadays the scene of complex logistic problems integrating diﬀerent decision layers. This paper addresses the Joint Order Batching, Picker Routing and Sequencing Problem with Dead-lines (JOBPRSP-D) in rectangular warehouses. To tackle the prob-lem an exponential linear programming formulation is proposed. It is WebDistinguished from the past studies, a comprehensive nonlinear mixed integer optimization model is developed to simultaneously determine three decisions, including order batching, batch sequencing, and picker׳s routing, under the consideration of the minimum total tardiness of customer orders. The IOBSRP can be proven as a NP-Hard problem.
