Abstract
Zone picking refers to the partitioning of a warehouse picking area into non-overlapping zones, with each zone assigned to an order picker responsible for retrieving the corresponding parts of an order. In sequential zone picking, orders flow through these zones in a fixed-zone visitation sequence. While this system maintains a high pick rate, it also increases task repetitiveness, leading to significant levels of physical fatigue among order pickers and an increased risk of injuries.
To address this issue, we introduce the Sequential Zone Picking Systems Order and Break Sequencing Problem under Energy Expenditure (SZPOBS-EE). Our solution approach uses metaheuristic methods, like Variable Neighborhood Search or Parallel Tempering, to sequence orders and schedule breaks, balancing order throughput and physical fatigue. Through a numerical study, we benchmark our metaheuristics against a MIP.
