Decision Rules for Robotic Mobile Fulfillment Systems
The Robotic Mobile Fulfillment Systems (RMFS) is a new type of robotized, parts-to-picker material handling system, designed especially for e-commerce warehouses. Robots bring movable shelves, called pods, to workstations where inventory is put on or removed from the pods. This paper simulates both the pick and replenishment process and studies the order assignment, pod selection and pod storag...
متن کاملPath planning for Robotic Mobile Fulfillment Systems
This paper presents a collection of path planning algorithms for realtime movement of multiple robots across a Robotic Mobile Fulfillment System (RMFS). Robots are assigned to move storage units to pickers at working stations instead of requiring pickers to go to the storage area. Path planning algorithms aim to find paths for the robots to fulfill the requests without collisions or deadlocks. ...
متن کاملInventory Allocation in Robotic Mobile Fulfillment Systems
A Robotic Mobile Fulfillment System is a recently developed automated, parts-topicker material handling system. Robots can move storage shelves, also known as inventory pods, between the storage area and the workstations and can continually reposition them during operations. This paper shows how to optimize three key decision variables: (1) the number of pods per product (2) the ratio of the nu...
متن کاملRAWSim-O: A Simulation Framework for Robotic Mobile Fulfillment Systems
This paper deals with a new type of warehousing system, Robotic Mobile Fulfillment Systems (RMFS). In such systems, robots are sent to carry storage units, so-called “pods,” from the inventory and bring them to human operators working at stations. At the stations, the items are picked according to customers’ orders. There exist new decision problems in such systems, for example, the reallocatio...
متن کاملActive repositioning of storage units in Robotic Mobile Fulfillment Systems
In our work we focus on Robotic Mobile Fulfillment Systems in e-commerce distribution centers. These systems were designed to increase pick rates by employing mobile robots bringing movable storage units (so-called pods) to pick and replenishment stations as needed, and back to the storage area afterwards. One advantage of this approach is that repositioning of inventory can be done continuousl...
