Simulation compares two aisle robot picking configurations
1 reports · 1 sources
Mohsen Reda Mahmoud Moursi used discrete-event simulation to compare two implemented in-aisle robot picking configurations. Without an onboard tote lift mechanism, two tier-restricted shuttles serve two test tiers; with a lift mechanism, one shuttle remains on the horizontal level while the onboard mechanism moves the order tote to the adjacent upper tier to complete picking. The study notes that task locations in the two configurations are sampled from different sets of selectable tiers, so the results correspond to a "configuration plus task generation" combination rather than isolating the effect of the five-second tote lifting operation at identical picking locations. The study did not quantify system-level maximum throughput, investment cost, or reliability.

- Resource-Performance Trade-offs in Intra-Aisle Robotic Picking: A Discrete-Event Simulation Comparison of Shuttle Configurations With and Without an Onboard Tote Lift
A discrete-event simulation study compared two implemented intra-aisle robotic picking configurations: without an onboard tote lift, two level-captive shuttles serve the two tested levels; with the lift, one shuttle remains on its horizontal level and its onboard mechanism moves the order tote to the adjacent upper level to complete picks.
