The document discusses supply chain management (SCM). It defines SCM as the management of relationships between suppliers, manufacturers, warehouses, distribution centers, and customers to deliver value to customers at a low cost. The goal of SCM is to optimize efficiency through integrating these entities. The document also describes how SCM has evolved from a "push" model driven by forecasts to a "pull" model driven by actual customer demand.

4. 1.1 Overview of Supply Chain
Supply chain (also called value chain or demand chain), is
the network of the involved companies, through upstream
and downstream linkages, in the different processes and
activities that produce value in the form of products and
services in the hands of the ultimate consumer. For
example, a shirt manufacturer is a part of a supply chain
that goes upstream through the weavers of fabrics to the
manufacturers of fibers, and downstream through
distributors and retailers to the final consumer. Each of
these organizations in the chain is dependent upon each
other.
Y.Serroukh – Anglais Commercial 4

5. 1.2 The Definition of SCM
There are various definitions of different edition. But in general, Supply
chain management means 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. The
supply chain arrangement links a firm and its distributive and supplier
network to end customers.
The integrated value-creation process must be managed from material
procurement to end-customer product delivery. The integrated supply
chain management shifts traditional channel arrangements from
loosely linked groups of independent businesses that buy and sell
inventory to each other toward a coordinated initiative to increase
market impact, overall efficiency, continuous improvement, and
competitiveness.

• A set of approaches used to efficiently integrate
– Suppliers
– Manufacturers
– Warehouses
– Distribution centers
• So that the product is produced and distributed
– In the right quantities
– To the right locations
– And at the right time
• System-wide costs are minimized
• Service level requirements are satisfied
Y.Serroukh – Anglais Commercial 7

8. 1.4 Difficulties
• Uncertainty is inherent to every supply chain
– Travel times
– Breakdowns of machines and vehicles
– Weather, natural catastrophe, war
– Local politics, labor conditions, border issues
• The complexity of the problem to globally optimize a
supply chain is significant
– Minimize internal costs
– Minimize uncertainty
– Deal with remaining uncertainty
Y.Serroukh – Anglais Commercial 8

9. 1.5 History of SCM
• 1960’s - Inventory Management Focus, Cost Control
• 1970’s - MRP & BOM - Operations Planning
• 1980’s - MRPII, JIT - Materials Management, Logistics
• 1990’s - SCM - ERP - “Integrated” Purchasing,
Financials, Manufacturing, Order Entry
• 2000’s - Optimized “Value Network” with Real-Time
Decision Support; Synchronized & Collaborative
Extended Network

10. 1.6 Reasons for Developing Supply
Chains
 Greater competitive advantage
 Greater value to consumers
 Reduces the lead time gap
 Faster and smaller deliveries to intermediate customers
 Introduces the concept of increased shareholder value
 These reasons give rise to the notion that in future,
we will see supply chains competing with supply chains
rather than competition between organizations.
Y.Serroukh – Anglais Commercial 10

11. 1.7 The Goal of SCM
Since World War II, with the development of the operations
research and management science, there has been an increasing
interest in supply chain planning and management. Working
together, supply chain planners/managers and all members of
the front, middle and back end of the supply chain may enhance
revenue, cost control, and asset utilization as well as customer
satisfaction.
Furthermore, software for optimization has been embraced by
all of these parties, as it offers mathematical modeling solutions
to supply chain problems. For example, a software package
might provide an optimum delivery route of the products, from
supplier to manufacture. In conclusion, the goal is to optimize
efficiency through supply chain management.

13. The Evolving Supply Chain
Y.Serroukh – Anglais Commercial 13

14. 2.1 Supply Chain Integration :
Push Strategies
• Classical manufacturing supply chain strategy
• Manufacturing forecasts are long-range
– Orders from retailers’ warehouses
• Longer response time to react to marketplace changes
– Unable to meet changing demand patterns
– Supply chain inventory becomes obsolete as demand for certain products
disappears
• Increased variability (Bullwhip effect) leading to:
– Large inventory safety stocks
– Larger and more variably sized production batches
– Unacceptable service levels
– Inventory obsolescence
• Inefficient use of production facilities (factories)
– How is demand determined? Peak? Average?
– How is transportation capacity determined?
• Examples: Auto industry, large appliances, others?
Y.Serroukh – Anglais Commercial 14

15. 2.2 Supply Chain Integration :
Pull Strategies
• Production and distribution are demand-driven
– Coordinated with true customer demand
• None or little inventory held
– Only in response to specific orders
• Fast information flow mechanisms
– POS data
• Decreased lead times
• Decreased retailer inventory
• Decreased variability in the supply chain and especially at
manufacturers
• Decreased manufacturer inventory
• More efficient use of resources
• More difficult to take advantage of scale opportunities
• Examples: Dell, Amazon
Y.Serroukh – Anglais Commercial 15

16. 2.3 Supply Chain Integration :
Push/Pull Strategies
• Hybrid of “push” and “pull” strategies to overcome disadvantages of each
• Early stages of product assembly are done in a “push” manner
– Partial assembly of product based on aggregate demand forecasts (which are
more accurate than individual product demand forecasts)
– Uncertainty is reduced so safety stock inventory is lower
• Final product assembly is done based on customer demand for specific product
configurations
• Supply chain timeline determines “push-pull boundary”
