Strategic or Operational
Two types of decisions in supply chain
management
Strategic –design and policy
Operational –day-today activities
Major decisions areas
Location
Production
Inventory
Distribution

17. 11-17
Logistics
Refers to the movement of materials and
information within a facility and to incoming
and outgoing shipments of goods and
materials in a supply chain

Distribution requirements planning
(DRP) is a system for inventory
management and distribution planning
Extends the concepts of MRPII
Distribution Requirements
Planning

21. 11-21
Management uses DRP to plan and
coordinate:
Transportation
Warehousing
Workers
Equipment
Financial flows
Uses of DRP

22. 11-22
E-Business: the use of electronic
technology to facilitate business
transactions
Applications include
Internet buying and selling
E-mail
Order and shipment tracking
Electronic data interchange
E-Business

23. 11-23
Companies can:
Have a global presence
Improve competitiveness and quality
Analyze customer interests
Collect detailed information
Shorten supply chain response times
Realize substantial cost savings
Create virtual companies
Level the playing field for small companies
Advantages E-Business

24. 11-24
Customer expectations
Order quickly -> fast delivery
Order fulfillment
Order rate often exceeds ability to fulfill it
Inventory holding
Outsourcing loss of control
Internal holding costs
Disadvantages of E-Business

25. 11-25
Reverse Logistics
Reverse logistics–the backward flow of
goods returned to the supply chain
Processing returned goods
Sorting, examining/testing, restocking, repairing
Reconditioning, recycling, disposing
Gatekeeping–screening goods to prevent
incorrect acceptance of goods
Avoidance–finding ways to minimize the
number of items that are returned

26. 11-26
Effective Supply Chain
Requires linking the market, distribution
channels processes, and suppliers
Supply chain should enable members to:
Share forecasts
Determine the status of orders in real time
Access inventory data of partners

27. 11-27
Successful Supply Chain
Trust among trading partners
Effective communications
Supply chain visibility
Event-management capability
The ability to detect and respond to
unplanned events
Performance metrics

RFID Technology
Used to track goods in supply chain
RFID tag attached to object
Similar to bar codes but uses radio frequency
to transmit product information to receiver
RFID eliminates need for manual counting
and bar code scanning

30. 11-30
CPFR
Collaborative Planning, Forecasting, and
Replenishment
Focuses on information sharing among
trading partners
Forecasts can be frozen and then
converted into a shipping plan
Eliminates typical order processing

31. 11-31
CPFR Process
Step 1 –Front-end agreement
Step 2 –Joint business plan
Steps 3-5 –Sales forecast
Steps 6-8 –Order forecast collaboration
Step 9 –Order generation/delivery execution

32. 11-32
CPFR Results
Nabisco and Wegmans
50% increase in category sales
Wal-mart and Sara Lee
14% reduction in store-level inventory
32% increase in sales
Kimberly-Clark and Kmart
Increased category sales that exceeded
market growth

Supply Chain Performance Drivers
1.Quality
2.Cost
3.Flexibility
4.Velocity
5.Customer service

35. 11-35
Velocity
Inventory velocity
The rate at which inventory(material) goes
through the supply chain
Information velocity
The rate at which information is
communicated in a supply chain

36. 11-36
Barriers to integration of organizations
Getting top management on board
Dealing with trade-offs
Small businesses
Variability and uncertainty
Long lead times
Challenges

37. 11-37
1.Lot-size-inventory
Bullwhip effect
2.Inventory-transportation costs
Cross-docking
3.Lead time-transportation costs
4.Product variety-inventory
Delayed differentiation
5.Cost-customer service
Disintermediation
Trade-offs

38. 11-38
Trade-offs
Bullwhip effect
Inventories are progressively larger moving
backward through the supply chain
Cross-docking
Goods arriving at a warehouse from a
supplier are unloaded from the supplier’s
truck and loaded onto outbound trucks
Avoids warehouse storage

39. 11-39
Trade-offs
Delayed differentiation
Production of standard components and
subassemblies, which are held until late in
the process to add differentiating features
Disintermediation
Reducing one or more steps in a supply
chain by cutting out one or more
intermediaries
