64  Logistics and Supply Chain Management

64.1 Concepts

Logistics = the process of planning, implementing and controlling the efficient flow and storage of goods, services and related information from point of origin to point of consumption to meet customer requirements — Council of Supply Chain Management Professionals (CSCMP). Supply Chain Management (SCM) = the integrated coordination of all activities involved in sourcing, conversion and logistics across the network of organisations from raw materials to end customer. Martin Christopher (Cranfield) is the foundational scholar in Europe; Sunil Chopra (Kellogg) and David Simchi-Levi (MIT) in the US.

TipWorking definitions
  • CSCMP: “SCM encompasses the planning and management of all activities involved in sourcing and procurement, conversion, and all logistics-management activities.”
  • Martin Christopher: “Logistics is the process of strategically managing the procurement, movement and storage of materials, parts and finished inventory through the organisation and its marketing channels.”
  • APICS: “Supply chain — the global network used to deliver products and services from raw materials to end customers.”

Inclusion Subset of SCM Includes logistics, sourcing, conversion

64.3 The 7 Rs of Logistics

Right Product · Place · Time · Quantity · Quality · Customer · Cost — the goal of logistics.

64.4 Components of Logistics

TipLogistics activities
  • Order processing.
  • Inventory management.
  • Warehousing and storage.
  • Transportation — rail, road, air, sea, pipeline, intermodal.
  • Material handling.
  • Protective packaging.
  • Customer service / Logistics service quality.
  • Reverse logistics — returns, recycling.

64.5 Modes of Transport

TipTransport modes — comparison
Mode Speed Cost Capacity Use case
Road High Medium Medium Last-mile, FTL, LTL
Rail Medium Low High Bulk, long distance
Sea Low Lowest Very High International trade, bulk
Air Highest Highest Low High-value, perishable
Pipeline Slow Very low High Oil, gas, water
Intermodal / Multi-modal Variable Variable High Containerised, global

64.6 Supply Chain Drivers

TipChopra-Meindl’s six SC drivers
Driver Focus
Facilities Where, how, capacity
Inventory What, how much, when
Transportation How, modes
Information Sharing, visibility
Sourcing Who supplies what
Pricing How priced through chain

64.7 Bullwhip Effect — Forrester (1961)

Jay W. Forrester (MIT, Industrial Dynamics 1961) — small variations in customer demand cause amplified variations upstream in the supply chain. Hau Lee (Stanford, 1997) systematised it as the Bullwhip Effect with four causes.

TipHau Lee’s four causes of bullwhip
  • Demand forecast updating — over-reaction.
  • Order batching — periodic ordering creates lumpy demand.
  • Price fluctuations — promotions cause hoarding.
  • Rationing / shortage gaming — over-ordering when supply tight.

64.7.1 Counter-measures

TipReducing the bullwhip
  • Information sharing (EDI, ERP).
  • Smaller, more frequent orders.
  • Stable everyday prices (EDLP).
  • Allocation based on past sales.
  • Vendor-Managed Inventory (VMI).
  • Collaborative Planning, Forecasting & Replenishment (CPFR).

64.8 Inventory Strategies

TipInventory strategies
  • EOQ — F.W. Harris (1913), Wilson (Topic 51).
  • Reorder Point = Lead-time × daily usage + safety stock.
  • JIT (Just-in-Time) — Toyota, Taiichi Ohno.
  • Kanban — Toyota pull system.
  • MRP / MRP II / ERP — Joseph Orlicky (1975).
  • VMI — supplier manages buyer’s inventory.
  • DRP — Distribution Requirements Planning.
  • Cross-docking — minimise warehouse storage.

64.9 Push vs Pull

TipPush vs Pull SC strategies
  • Push — production based on forecast; pushes to customer (traditional FMCG).
  • Pull — production triggered by actual demand (Dell BTO, Amazon).
  • Push-Pull hybrid — common in modern supply chains (push to DC, pull to customer).

64.10 Lean and Agile Supply Chains

TipLean vs Agile
Dimension Lean Agile
Focus Cost, efficiency Responsiveness
Demand Predictable Volatile
Lead times Long, planned Short
Product life cycle Long Short
Example Toyota Zara

Leagile combines both — lean for stable demand, agile for volatile.

64.11 Strategic Fit — Chopra-Meindl

Strategic fit = matching SC capabilities (responsive vs efficient) with competitive strategy. Plot on Zone of Strategic Fit.

64.12 Value Chain (Porter) and SCM (Stevens)

Graham Stevens (1989) — four stages of SC integration:

TipStevens’ four stages of SC evolution
  • Stage 1 — Baseline / Fragmented.
  • Stage 2 — Functional integration.
  • Stage 3 — Internal integration.
  • Stage 4 — External integration.

64.13 SCOR Model — Supply Chain Council

The Supply Chain Operations Reference (SCOR) model — five core management processes:

TipSCOR — five processes
  • Plan — supply and demand balancing.
  • Source — procurement.
  • Make — production.
  • Deliver — order management, transportation.
  • Return — reverse logistics.
  • (Modern: Enable added).

2PL Asset-based carriers
3PL (Third-Party Logistics) Outsourced logistics provider — DHL, FedEx, Blue Dart, Delhivery
