Supply Chain
 All activities associated with the flow
and transformation of goods and
services from raw materials to the end
user, the customer
 A sequence of business activities
from suppliers through customers
that provide the products, services,
and information to achieve customer
satisfaction

The Supply Chain
Information
Suppliers
Producers
Distributors
Customers
Materials,
parts, subassemblies,
and
services
Finished
goods, end
products
and services
Package
and delivery
Total
satisfaction
with quality,
price,
delivery, and
service

Supply Chain Management
 Synchronization of activities
required to achieve maximum
competitive benefits
 Coordination, cooperation, and
communication
 Rapid flow of information
 Vertical integration
4
Supply Chain Uncertainty
 Forecasting, lead times, batch
ordering, price fluctuations, and
inflated orders contribute to
variability
 Inventory is a form of insurance
 Distorted information is one of
the main causes of uncertainty
5
Information in the
Supply Chain
 Centralized coordination of
information flows
 Integration of transportation,
distribution, ordering, and production
 Direct access to domestic and global
transportation and distribution
channels
 Locating and tracking the movement
of every item in the supply chain
6
Information in the
Supply Chain
 Consolidation of purchasing from all
suppliers
 Intercompany and intracompany
information access
 Data interchange
 Data acquisition at the point of origin
and point of sale
 Instantaneous updating of inventory
levels
7
Electronic Business
 Replacement of physical processes
with electronic ones
 Cost and price reductions
 Reduction or elimination of
intermediaries
 Shortening transaction times for
ordering and delivery
 Wider presence and increased visibility
8
Electronic Business
 Greater choices and more information for
customers
 Improved service
 Collection and analysis of customer data
and preferences
 Virtual companies with lower prices
 Leveling the playing field for smaller
companies
 Gain global access to markets & customers
9
Electronic Data Interchange
 Computer-to-computer exchange of
business documents in a standard
format
 Quick access, better customer service,
less paperwork, better communication,
increased productivity, improved
tracing and expediting, improves billing
and cost efficiency
10
Bar Codes
 Computer readable codes attached to
items flowing through the supply chain
 Generates point-of-sale data which is
useful for determining sales trends,
ordering, production scheduling, and
deliver plans

The Internet
 Instant global access to organizations,
individuals, and information sources
 Fundamentally changes the way
organizations do business
 Removed geographic
barriers
 Adds speed and accessibility
to the supply chain
12
Intranets and Extranets
 Intranets are internet-like networks that
operate within a single organization
 Extranets are intranets that can be
connected to the global internet
 Difference is in who has access to the
system
13
IT Issues
 Increased benefits and sophistication
come with increased costs
 Efficient web sites do not necessarily
mean the rest of the supply chain will
be as efficient
 Security problems are very real
 Partnership and trust are important
elements that may be new to business
relationships
14
Suppliers
 Purchased materials account for about
half of manufacturing costs
 Materials, parts, and service must be
delivered on time, of high quality, and
low cost
 Suppliers should be integrated into
their customers’ supply chains
 Partnerships should be established
 On-demand delivery (JIT) is a frequent
requirement
15
Sourcing
 Relationship between customers and
suppliers focuses on collaboration and
cooperation
 Outsourcing has become a long-term
strategic decision
 Organizations focus on core
competencies
 Single-sourcing is
increasingly a part
of supplier relations
16
E-Procurement
 Business-to-business commerce
conducted on the Internet
 Benefits include lower transaction
costs, lower prices, reduce clerical labor
costs, and faster ordering and delivery
times
 Currently used more for indirect goods
 E-Marketplaces service industry-specific
companies and suppliers

Supply Chain

Distribution
 The actual movement of products
and materials between locations
 Handling of materials and products at
receiving docks, storing products,
packaging, and shipping
 Often called logistics
 Driving force today
is speed
 Particularly important
for Internet dot-coms

Distribution Centers
and Warehousing
 DCs are some of the largest business
facilities in the United States
 Trend is for more frequent orders in
smaller quantities
 Flow-through facilities and automated
material handling
 Final assembly and product
configuration may be done at the DC
21
Warehouse Management
Systems
 Highly automated systems
 Controls item putaway, picking,
packing, and shipping
 Transportation management,
order management, yard
management, labor management,
warehouse optimization
22
Vendor-Managed Inventory
 Manufacturers generate orders, not
distributors
 Stocking information is accessed
using EDI
 A first step towards supply chain
collaboration
 Increased speed, reduced errors, and
improved service
23
Collaborative Distribution
and Outsourcing
 Collaborative planning, forecasting, and
replenishment (CPFR)
 Internet-based exchange of data and
information
 Significant decrease in inventory levels
and more efficient logistics
 Companies focus on core competencies
24
Transportation
 Important element, often
overlooked
 Common methods are railroads,
trucking, water, air, intermodal,
package carriers, and pipelines
25
Railroads
 150,000 miles in US
 Low cost, high-volume
 Improving flexibility
 intermodal service
 double stacking
26
Trucking
 Most used mode in US
 Flexible, small loads
 Consolidation,
Internet load match sites
 Part of TQM supplier-customer
relationship
 Single sourcing reduces number of
trucking firms serving a company
27
Air
 Rapidly growing segment of
transportation industry
 Lightweight, small items
 Quick, reliable,
expensive
 Major airlines
and US Postal Service,
UPS, FedEx, DHL
28
Package Carriers
 FedEx, UPS, US Postal Service, DHL
 Significant growth driven by
e-businesses
 Use several modes
of transportation
 Expensive
 Fast and reliable
 Innovative use of
technologies
29
Intermodal
 Combination of several modes of
transportation
 Most common are truck/rail/truck
and truck/water/rail/truck
 Enabled by the
use of containers
30
Water
 One of oldest means of transport
 Low-cost, high-volume, slow
 Bulky, heavy and/or large items
 Standardized shipping containers
improve service
 The most common
form of international
shipping
31
Pipelines
 Primarily for oil & refined oil
products
 Slurry lines carry coal or kaolin
 High capital investment
 Low operating costs
 Can cross difficult terrain
32
Internet Transportation
Exchanges
 Bring together shippers and carriers
 Initial contact, negotiations,
auctions
 Typically only one
form of transportation,
intermodal exchanges
have been difficult to develop
