63 Logistics and Supply Chain Management
63.1 What is Logistics? Supply Chain Management?
Logistics is the part of supply-chain management that plans, implements, and controls the efficient, effective forward and reverse flow and storage of goods, services, and related information between the point of origin and the point of consumption to meet customer requirements — Council of Supply Chain Management Professionals (CSCMP).
Supply Chain Management (SCM) is the broader concept — the integrated management of all activities, information and money flows from raw-material sourcing to the final consumer. SCM is therefore a cross-firm activity; logistics is within-firm.
TipThree Working Definitions
| Source | Definition | What it foregrounds |
|---|---|---|
| CSCMP | “Process that plans, implements and controls the efficient, effective forward and reverse flow and storage of goods, services and information between origin and consumption.” | Flow + storage |
| Christopher | “SCM = the management of upstream and downstream relationships with suppliers and customers to deliver superior customer value at less cost to the supply chain as a whole.” | Relationships |
| Chopra & Meindl | “A supply chain consists of all parties involved, directly or indirectly, in fulfilling a customer request — including manufacturers, suppliers, transporters, warehouses, retailers, and customers themselves.” | Network |
63.2 Logistics vs Supply Chain Management
TipLogistics vs SCM
| Feature | Logistics | SCM |
|---|---|---|
| Scope | Within the firm — flow and storage | Across firms — entire chain |
| Focus | Cost-efficiency, service levels | Strategic integration |
| Time horizon | Operational + tactical | Strategic + tactical |
| Activities | Transport, warehouse, inventory, packaging | Logistics + procurement, demand planning, manufacturing, distribution, returns |
63.3 Components of Logistics
TipSix Components of Logistics
| Component | What it does |
|---|---|
| Order processing | Receive, enter, fulfil, follow up |
| Inventory management | What to hold, where, how much |
| Warehousing | Store, pick, pack |
| Materials handling | Movement within facilities |
| Transportation | Mode mix — road / rail / air / sea / pipeline |
| Packaging | Protection, presentation, information |
63.3.1 Modes of Transport
TipFive Modes of Transport — Trade-offs
| Mode | Speed | Cost | Best for |
|---|---|---|---|
| Road | Medium | Medium | Door-to-door; flexibility |
| Rail | Medium | Low | Bulk over long distance |
| Air | High | High | Time-critical, high-value |
| Sea | Low | Lowest per tonne-km | Bulk, international |
| Pipeline | Continuous | Low operating | Liquids, gases |
63.4 SCM — Five Building Blocks
Sunil Chopra and Peter Meindl’s standard SCM textbook organises the discipline around five drivers (chopramendl2019?):
TipChopra & Meindl’s Five Supply-Chain Drivers
| Driver | What it captures |
|---|---|
| Facilities | Plants, warehouses (location, capacity, role) |
| Inventory | Cycle, safety, seasonal, in-transit |
| Transportation | Mode, route, design |
| Information | Data sharing, IT systems, demand signals |
| Sourcing | In-house vs outsource; supplier base |
| Pricing | Pricing scheme that aligns demand with capacity |
63.5 Strategic Frameworks in SCM
TipTwo Foundational SCM Frameworks
| Framework | Authors | Idea |
|---|---|---|
| Efficient vs Responsive Supply Chain | Marshall Fisher (1997) | Functional products → efficient SC; innovative products → responsive SC |
| Lean vs Agile | Hau Lee (2004) | Lean (efficiency, low cost), Agile (flexibility), Hybrid (Leagile) |
63.5.1 Bullwhip Effect
The classic SCM phenomenon — small downstream demand variations amplify into large upstream inventory swings. Causes: order batching, rationing, demand forecasting errors, price fluctuations. Remedies: information sharing (POS, CPFR), VMI, EDLP, single-stage manufacturing.
63.6 Procurement and Strategic Sourcing
TipFive Steps in Strategic Sourcing
| # | Step |
|---|---|
| 1 | Spend analysis and category strategy |
| 2 | Supplier identification and assessment |
| 3 | Negotiation and supplier selection |
| 4 | Contract management |
| 5 | Performance review and supplier development |
The Kraljic Matrix (1983) classifies purchases on profit impact and supply risk — Strategic, Bottleneck, Leverage, Non-critical — and prescribes different sourcing strategies.
63.7 Warehousing and Inventory Models
Already met in topic 51. The standard tools:
TipInventory Models and Techniques
| Tool | What it does |
|---|---|
| EOQ | Optimal order quantity = √(2DS/H) |
| Reorder Point | (Lead time × usage) + Safety stock |
| ABC Analysis | Pareto: A items high value, C items low value |
| VED Analysis | Vital, Essential, Desirable |
| Just-in-Time (JIT) | Toyota; minimise inventory |
| Vendor-Managed Inventory (VMI) | Supplier manages buyer’s inventory |
63.8 Modern Themes in SCM
TipModern SCM Themes
| Theme | What it captures |
|---|---|
| Digital supply chain | IoT, AI/ML, blockchain, control towers |
| Omnichannel fulfilment | Buy anywhere, fulfil anywhere |
| Sustainable / Green SCM | Carbon footprint, circular economy |
| Resilience | Diversification, near-shoring, redundancy |
| 3PL / 4PL | Outsourced logistics; lead-logistics integration |
63.9 Indian Logistics Framework
TipIndian Logistics Framework
| Initiative / Body | Concerned with |
|---|---|
| National Logistics Policy, 2022 | Reduce logistics cost from ~14% of GDP toward 8% |
| PM GatiShakti, 2021 | National Master Plan for multi-modal connectivity |
| Goods and Services Tax, 2017 | Unified market; eliminated state-border check posts |
| ULIP (Unified Logistics Interface Platform) | Logistics data sharing |
| Dedicated Freight Corridors | Eastern and Western DFCs |
| Sagarmala (port-led) and Bharatmala (highways) | Sectoral programmes |
| Logistics Performance Index (World Bank) | International benchmark |
63.10 Practice Questions
Q 01
Logistics vs SCM
Easy
Logistics differs from SCM primarily in that:
View solution
Correct Option: B
Logistics is intra-firm flow and storage; SCM is the broader, cross-firm integration of upstream and downstream relationships.
Q 02
Drivers
Medium
Chopra and Meindl's six SC drivers include all of the following EXCEPT:
View solution
Correct Option: D
Six drivers: Facilities · Inventory · Transportation · Information · Sourcing · Pricing. Advertising is not one.
Q 03
Fisher
Medium
Marshall Fisher's classification of supply chains contrasts:
View solution
Correct Option: B
Fisher (1997): Efficient SC for functional products; Responsive SC for innovative products.
Q 04
Bullwhip
Medium
A common remedy for the bullwhip effect is:
View solution
Correct Option: B
Bullwhip is reduced by sharing demand data — POS, CPFR (Collaborative Planning, Forecasting, Replenishment), VMI.
Q 05
Kraljic
Medium
The Kraljic Matrix classifies purchases on:
View solution
Correct Option: A
Kraljic (1983): profit impact × supply risk → Strategic, Bottleneck, Leverage, Non-critical purchases.
Q 06
Modes
Easy
For very high-value, time-critical international shipments, the most appropriate mode is:
View solution
Correct Option: C
Air = high speed + high cost — used for time-critical, high-value shipments. Sea = bulk, low cost; rail = bulk over long distance.
Q 07
India NLP
Medium
India's National Logistics Policy was launched in:
View solution
Correct Option: C
NLP launched 2022; PM GatiShakti (multi-modal master plan) launched 2021.
Q 08
3PL
Medium
"3PL" in modern logistics refers to:
View solution
