An overview of logistics operations, including definitions, key concepts, and the importance of efficient logistics in supply chain management.
Introduction to Logistics Operations
Key concepts, components, and best‑practice principles
| Definition | The planning, implementation, and control of the efficient, effective flow and storage of goods, services, and related information from point of origin to point of consumption. |
|---|---|
| Goal | Satisfy customer demand while minimizing total cost. |
| Scope | Includes transportation, warehousing, inventory management, order fulfillment, material handling, and information flow. |
| Element | Main Functions | Typical Metrics |
|---|---|---|
| Transportation | Mode selection, routing, carrier management, freight consolidation | Delivery lead time, cost per ton‑mile, on‑time delivery (OTD) |
| Warehousing & Distribution Centers | Receiving, put‑away, storage, picking, packing, cross‑docking | Space utilization, order pick accuracy, dwell time |
| Inventory Management | Forecasting, safety stock, replenishment, cycle counting | Inventory turnover, days of inventory on hand (DOH), stock‑out rate |
| Material Handling | Equipment selection, layout design, automation (conveyors, robots) | Labor productivity, handling cost per unit |
| Information & Control Systems | ERP, WMS, TMS, RFID/barcode tracking, analytics | Data accuracy, system uptime, order cycle time |
| Reverse Logistics | Returns processing, refurbishment, recycling, disposal | Return rate, cost per return, recovery value |
(Flow can be visualized as a linear diagram with feedback loops for inventory replenishment and returns.)
| Category | KPI | Target Example |
|---|---|---|
| Cost | Total logistics cost (% of sales) | ≤ 12 % |
| Transportation cost per unit | $0.45/unit | |
| Service | On‑time delivery (OTD) | ≥ 98 % |
| Order fill rate | ≥ 99 % | |
| Efficiency | Warehouse labor cost per order | $2.50/order |
| Dock‑to‑stock time | ≤ 2 h | |
| Quality | Order accuracy | ≥ 99.9 % |
| Damage rate | ≤ 0.2 % | |
| Responsiveness | Lead time (order to delivery) | ≤ 5 days |
| Cycle‑time for returns | ≤ 7 days |
| Mode | Typical Use | Advantages | Disadvantages | |------|-------------|
