Airline Parts Warehouse Achieves $22,127 Annual Savings and 22% Productivity Gain by Automating Parts Dispatch

In aviation parts warehousing, order fulfillment speed is operationally critical — delayed components can ground aircraft and trigger downstream penalties. This SME warehouse had invested in automated inventory picking, but a 350-foot gap between its parts storage module and the shipping department created a persistent bottleneck that the automation could not address. Operators were repeatedly pulled from their stations to hand-carry individual parts to shipping for high-priority orders, then walk empty bins back to the storage module for reuse — a cycle repeated many times daily. These non-value-add transport runs directly eroded the productivity gains from automated picking, leaving the operation's true efficiency potential unrealized.

MūL Technologies' MARC® (Mobile Autonomous Robotic Carts) were deployed to take over the full interdepartmental shuttle loop that operators had been performing manually. Unlike conveyor systems or track-guided AGVs, MARC® requires no fixed track infrastructure or continuous Wi-Fi connectivity — a significant advantage for SME warehouse environments where capital expenditure on facility modifications is constrained. Setup took under 10 minutes per unit, enabling near-immediate deployment without changes to the existing automated picking system or floor layout. Once operational, MARC® autonomously transported picked parts from the inventory module to shipping and returned empty bins for reuse. Operators remained at their stations throughout, eliminating the workflow interruptions that had fragmented their productivity. No facility modifications, extended integration work, or dedicated IT infrastructure were required.

The operation achieved full return on its $14,995 investment in 8.13 months — a fast payback made more notable by the fact that MARC® utilization consistently remained below 20% of theoretical capacity. By eliminating manual transport runs, the warehouse reclaimed 36 hours of operator time per month, valued at a blended rate of $51.22 per hour including overhead. Annualized, this translated to $22,127.04 in recurring savings.

• 22% increase in overall operator productivity
• 9% productivity gain realized immediately upon deployment
• Full ROI achieved within the first year, at sub-20% equipment utilization

No headcount additions or facility expansions were required — gains came entirely from redeploying previously lost labor hours into value-add warehouse activity.

• Partial automation that stops at inventory picking leaves interdepartmental transport as an unresolved bottleneck — completing the material flow loop is essential to capturing full ROI from upstream automation investments.
• Low equipment utilization (under 20%) does not preclude strong financial returns when the per-hour labor cost is meaningful; utilization thresholds should not be the primary evaluation criterion for small autonomous cart deployments.
• Infrastructure-free autonomous cart solutions reduce deployment barriers for SMEs, enabling sub-12-month payback without capital-intensive facility modifications or lengthy integration projects.
• Immediate productivity impact at deployment validates low-disruption rollout strategies — solutions that work out of the box reduce change management risk in smaller operations.
