End-to-End MHE System Redesign
Current building had throughput constraint due to mechanical failure & system design. Led a full DMAIC-driven rebuild targeting two problem buckets: Machine & Throughput and Labor, Safety, Process, Ergonomics.
  • Process optimization → 3 touch points vs 5–7 → increased process rate/cycle time
  • Saved $6.8M/yr → 68% headcount reduction → streamlined flow
  • Flexible MHE → handles cases up to 50lb, increased storage cube by 21%
  • Tracking system (Jam Cam, MES, SDEN) → 20% reduced downtime
  • 100% safety hazard eliminated, 15% reduction in labor traffic incidents

Battery & Layout Optimization Tool
All sites used 100% hydrogen fuel PITs, requiring dedicated refueling time — causing downtime across all zones. Proposed converting dock PITs to Li-ion with opportunity charging.
  • Eliminated downtime at the dock entirely
  • Removed need for additional PITs and labor at dock
  • AI-powered Python script to optimize sub-system location → 5% layout efficiency gain
  • Increased man vs machine integration by 4%

One→Two-Sided Building Process Flow
One-sided flow caused 20% increased traffic at IB & OB junction, 20% reduced PIT process rate, and high-density labor distribution creating egress risk with 165 AAs at dock.
  • Streamlined traffic → eliminated 1-sided flow issue
  • Installed lift gates at every PIT/Ped zone → incidents reduced 4 → 1 per day
  • PIT process rate increased 17 → 22/25 Pph
  • Labor reduced from 165 → 85 AA at each dock area
