Course Objectives
Provide a review of supply chain management from a manufacturing, planning and control perspective 看法,远景Provide a basis for further study leading to APICS CPIM certification
APICS The Association for Operations Management, is a not-for-profit international education organization, offering certification programs, training tools and networking opportunities to increase workplace performance. It was founded in 1957 as the American Production and Inventory Control Society, and currently has more than 43,000 individual and corporate members in more than 10,000 companies worldwide. In April 2008, the organization relocated to Chicago.

Intermittent Process Characteristics
Intermittent lot / batch production
Work moves only to required stations
Many different parts processed at workstations
General-purpose machinery
Relatively easy to change product or volume
Complex and expensive production and inventory control
High WIP inventory levels; long lead time
© 2009 APICS CONFIDENTIAL AND PROPRIETARY© 2009 APICS CONFIDENTIAL AND PROPRIETARY1 26
Intermittent Manufacturing Layout
Intermittent manufacturing layout is called process layout
Also called functional or job shop layout
Equipment and operations grouped together by functional specialty
Similar types of skills and equipment in each department
Volume not high enough to justify assembly line
© 2009 APICS CONFIDENTIAL AND PROPRIETARY© 2009 APICS CONFIDENTIAL AND PROPRIETARY1 27
Flow Manufacturing Process
Workstations are in the sequence needed to make the product
Work flows at a nearly constant rate
Little work-in-process inventory

Flow Process Characteristics
Layout is called product layout
Fixed routings and dedicated machinery
Capital intensive
Two types of flow: repetitive/line and continuous
Repetitive = discrete units (Automoblie)
Continuous = not discrete (Steel/ Mixing, heating, cooling, ..)
Limited range of similar products
High product volumes
© 2009 APICS CONFIDENTIAL AND PROPRIETARY© 2009 APICS CONFIDENTIAL AND PROPRIETARY1 29
Advantages of Product Layout (Flow Mfg)
Little work-in-process inventory
Short throughput and manufacturing lead times
Lower unit cost
© 2009 APICS CONFIDENTIAL AND PROPRIETARY© 2009 APICS CONFIDENTIAL AND PROPRIETARY1 30
Project Manufacturing
Used for large, complex projects
Project remains in one location for assembly
Site layout
Avoids cost of moving the product

The Manufacturing Supply Chain
Introduction to Supply Chain Management
Session 1
© 2009 APICS CONFIDENTIAL AND PROPRIETARY© 2009 APICS CONFIDENTIAL AND PROPRIETARY1 34
Supply Chain Management Definitions
Supply chain: The global network used to deliver products and services from raw materials to end customers through an engineered flow of information, physical distribution, and cash.
Supply chain management: The design, planning, execution, control, and monitoring of supply chain activities with the objective of creating net value, building a competitive infrastructure, leveraging world-wide logistics, synchronizing supply with demand, and measuring performance globally.

Role of Materials Management
Demand Resources
Plan&
Control
– Balance company resources with demands– Balance conflicting objectives by:
• Maximizing the use of the firm’s resources• Providing the required level of customer service
– Involved with:• Manufacturing planning and control• Physical supply / distribution

Objectives of Manufacturing
The right products
Of the right quality
In the right quantities
At the right time
At minimum cost (right price)
