| dc.description.abstract | Order picking stands as the cornerstone of warehouse operations, requiring both efficiency and dependability. The quest for a swift and reliable order picking system has become a focal point in logistics. This study investigates two distinct warehouse systems, each holding its own unique characteristics and implications.
In the first warehouse system, I analyze the impact of storage assignment policies and routing policies on order picking performance in the warehouse with one front and one back cross aisle. Additionally, I explore the interplay between these two types of policies. Through numerous experiments conducted under various conditions, I examine factors such as warehouse aspect ratios, order list sizes, and diverse demand patterns. In the second warehouse system, I explore facilities with multiple cross aisles, where order pickers navigate aisles to retrieve items from storage. These cross aisles, situated at various points including the front, back, and between aisles, offer flexibility in routing. However, they also complicate storage assignment and route planning for order picking. I propose several storage assignment and routing policies tailored to warehouses with multiple cross aisles, investigating their impact on order picking performance. The findings from this study enrich the understanding of the complex relationship between storage assignment and routing policies across diverse warehouse settings. Ultimately, my research aims to improve the efficiency and accuracy of order picking systems within the constantly evolving logistics landscape. | en_US |
