  • Data-driven judgment, risk-based prioritization, and meeting critical-path deadlines.
  • Team leadership, coaching, and performance management.
• II.3 Physical and site demands
  • Frequent yard/warehouse walkdowns, occasional shop/factory visits; ability to use PPE and climb stairs/ladders.
  • Travel 20–40% based on campaign intensity; ability to handle time-zone calls and urgent after-hours escalations.
  • Capability to verify packaging, lifting, preservation, and basic dimensional checks on heavy components with proper assistance and lifting plans.

  • Reorder Point (ROP): \( ROP = dL + SS \)
    • \(d\): average demand per period, \(L\): lead time (periods), \(SS\): safety stock.
  • Safety Stock (cycle service level): \( SS = z \cdot \sigma_L \)
    • \(z\): service level factor, \( \sigma_L \): demand variability over lead time.
