What is a Supply Chain?What is a Supply Chain?
A supply chain consists of the flow of products and services from/to:
--Raw materials manufacturers SEE FIGURE 1.1--Intermediate products manufacturers--End product manufacturers--Wholesalers and distributors--Retailers and, --End customers
Connected by agents, transportation and storage activities, and
Integrated through sharing of information, planning, and processing activities\

What is Supply Chain Management?What is Supply Chain Management?
Here are two definitions:
The design and management of seamless, value-added process across organizational boundaries to meet the real needs of the end customer
-- Institute for Supply Management
Managing supply and demand, sourcing raw materials and parts, manufacturing and assembly, warehousing and inventory tracking, order entry and order management, distribution across all channels, and delivery to the customer
-- The Supply Chain Council

What Is the Goal of Supply Chain What Is the Goal of Supply Chain Management?.Management?.
Supply chain management is concerned with the efficient integration of suppliers, factories, warehouses and stores so that merchandise is produced and distributed:
– In the right quantities– To the right locations – At the right time
In order to– Minimize total system cost– Satisfy customer service requirements

Importance of Supply Chain Importance of Supply Chain ManagementManagement
* Firms have discovered value-enhancing and long term benefits
* Who benefits most? Firms with: - Large inventories
- Large number of suppliers
- Complex products
- Customers with large purchasing budgets
* Benefits
- Lower purchasing/inventory costs, higher quality/customer service

Firms practicing Supply Chain Management:
1. Start with key suppliers
2. Move on to other suppliers, customers, and shippers
3. Integrate second tier suppliers and customers (second tier refers to the customer’s customers and the supplier’s suppliers)

* Cost savings and better coordination of resources are reasons to employ Supply Chain Management
-- Bullwhip Effect- the magnification of safety stocks and costs based on separate forecasts and uncoordinated planning and sharing of information along the supply chain (Ex. 1.1)
* Reducing the bullwhip effect occurs through:
-- Process integration- Interdependent activities can lead to improved quality, reduced cycle time, better production methods, better forecasts, less safety stock, etc.

Purchasing:
•Long term relationships•Supplier management- improved performance through-
-- Supplier evaluation (determining supplier capabilities and performance)
-- Supplier certification (third party or internal certification to assure product quality and service compliance)
•Strategic partnerships- successful and trusting, long-term relationships with top-performing suppliers

Operations:-- Demand management- match demand to available capacity
-- Linking buyers & suppliers via MRP and ERP systems
-- Use JIT to improve the “pull” of materials to reduce inventory levels

Distribution:-- Transportation management- tradeoff decisions between cost & timing of delivery/customer service via trucks, rail, water & air
-- Customer relationship management- strategies to ensure deliveries, resolve complaints, improve communications, & determine service requirements

Integration:
-- Supply Chain Integration- when supply chain participants work for common goals. Requires intrafirm functional integration. Based on efforts to change attitudes & adversarial relationships
-- Global Supply Chains- advantages that accrue from sourcing from larger global market e.g., lower cost & higher quality suppliers. May involve operating exposure, which is risk found in foreign settings
-- Supply Chain Performance Measurement- Crucial for firms to know if procedures are working

Why is Global Optimization Hard?Why is Global Optimization Hard?
–The supply chain is complex–Different facilities have conflicting objectives–The supply chain is a dynamic system–The power structure changes–The system varies over time

Can’t Forecasting Help?Can’t Forecasting Help?
Forecasting is always wrong The longer the forecast horizon the worse the
forecast End item forecasts are even more wrong

Why Is Uncertainty Hard to Deal With?Why Is Uncertainty Hard to Deal With?
* Matching supply and demand is difficult.* Forecasting doesn’t solve the problem.* Inventory and back-order levels typically fluctuate widely
across the supply chain.* Demand is not the only source of uncertainty:
– Lead times– Yields– Transportation times– Natural Disasters– Component Availability
