Just-in-time publishing for textbooks on demand publishing a growing

Construction firms receiving material
just as needed
What is JIT ?
Producing only what is needed, when it is
needed
A philosophy
An integrated management system
JIT’s mandate:
Eliminate all waste
Lean Operations:
Best Implementation is Toyota Production System
• TPS is a production management system that aims for the “ideal” through
continuous improvement
• Includes, but goes way beyond JIT. Pillars:
– Synchronization
• Reduce transfer batch sizes
• Level load production
• Pull production control systems (vs. push): Kanban
• Quality at source
• Layout: Cellular operations
– Continuous Improvement (Kaizen): through visibility & empowerment
....
Toyota’s waste elimination in Operations
1. Overproduction
2. Waiting
3. Inessential handling
4. Non-value adding processing
5. Inventory in excess of immediate needs
6. Inessential motion
7. Correction necessitated by defects

Flexible Resources
Multifunctional workers
General purpose machines
Study operators & improve
operations
The Push System
• Pre-planned issues of supplies/merchandise
regardless of customer demand criteria
• Creates excess and shortages
• not efficient over the long run
The Pull System
Material is pulled through the system
when needed
Reversal of traditional push system where
material is pushed according to a schedule
Forces cooperation
Prevent over and underproduction
Kanban Production Control System
Kanban card indicates standard quantity of
production
Derived from two-bin inventory system
Kanban maintains discipline of pull production
Production kanban authorizes production
Withdrawal kanban authorizes movement of
goods
A Sample Kanban
Types of Kanbans
Bin Kanban - when bin is empty replenish
Kanban Square
Marked area designed to hold items
Signal Kanban
Triangular kanban used to signal production at the
previous workstation
Material Kanban
Used to order material in advance of a process
Supplier Kanbans
Rotate between the factory and suppliers
Components of Lead Time
Processing time
Reduce number of items or improve
efficiency
Move time
Reduce distances, simplify movements,
standardize routings
Waiting time
Better scheduling, sufficient capacity
Setup time
Generally the biggest bottleneck
Common Techniques for Reducing Setup
Time
•
•
•
•
•
•
•
Preset Buttons/settings
Quick fasteners
Reduce tool requirements
Locator pins
Guides to prevent misalignment
Standardization
Easier movement
Uniform Production
Results from smoothing production
requirements
Kanban systems can handle +/- 10%
demand changes
Smooths demand across planning horizon
Mixed-model assembly steadies
component production
Quality at the Source
Jidoka is authority to stop production line
Andon lights signal quality problems
Undercapacity scheduling allows for
planning, problem solving & maintenance
Visual control makes problems visible
Poka-yoke prevents defects (mistake proof
the system)
Kaizen
Continuous improvement
Requires total employment involvement
Essence of JIT is willingness of workers to
Spot quality problems
Halt production when necessary
Generate ideas for improvement
Analyze problems
Perform different functions

Better relations with

Simplified scheduling and

Increased capacity
Better use of human
resources
More product variety
Continuous Process
Improvement
JIT Implementation
Use JIT to finely tune an operating system
Somewhat different in
USA than Japan
JIT is still evolving
JIT as an inventory reduction program isn’t
for everyone - JIT as a CPI program is!
Some systems need Just-inCase inventory

Terrorism Risk Insurance
U.S. Terrorism Risk Insurance Act (TRIA) – property and casualty insurance experts are
helping clients with interests in the United States make informed decisions about
terrorism coverage.
U.S. President George W. Bush signed the Terrorism Risk Insurance Act (TRIA) into law
in November 2002 to stimulate business investment that had slowed to a trickle after
the events of September 11, 2001. The law creates a three-year federal program that
backs up insurance companies and guarantees that certain terrorist-related claims will
be paid.
TRIA is a short-term measure designed to give the insurance market time to recover
and develop new solutions.
On December 26, 2007, the President signed into law
the Terrorism Risk Insurance Program Reauthorization
Act of 2007 which extends the Terrorism Risk Insurance
Act through December 31, 2014. The law extends the
temporary federal Program that provides for a transparent
system of shared public and private compensation for
insured losses resulting from acts of terrorism.
Supply Chain Security
“We have proved to our management
that good security is good
business.”
— Ann Lister of Texas Instruments
Risk
Supply Chains are inherently
complex, dynamic, and fluid,
characterized by uncertainty,
ambiguity, and friction. These
characteristics cloud the operating
environment: they create risks
Risk Assessment
• Terrorism
• Port Security – over 12 million
containers annually to the US; 200
million world wide
• Port Security – 300 US Ports
• Longshoremen Strike – 2002
• Potential Airport Attack – LAX;
MPS; LGA
Risk Assessment
“If you do things the way you’ve
always done them, you’ll get the
same things you’ve always got.”
-Darrell Waltrip
This is not your Dad’s Supply Chain!

Other issues
• 9000 distribution centers in the
Netherlands
• 2000 - $64.4 billion USD in logistics
and distribution in The Netherlands
SAFE Port Act
• The SAFE Port Act codified into
law a number of programs to
improve security of U.S. ports,
such as:
• Additional requirements for
maritime facilities
• Creation of the Transportation
Worker Identification Credentials
• Establishment of interagency
operational centers for port
security
Safe Port Act
• Container Security Initiative
• Foreign port assessments
• Customs Trade Partnership Against
Terrorism
Container Security Initiative
• CSI consists of four core elements:
• Using intelligence and automated
information to identify and target
containers that pose a risk for
terrorism.
• Pre-screening those containers that
pose a risk at the port of departure
before they arrive at U.S. ports.
• Using detection technology (X-Rays) to
quickly pre-screen containers that
pose a risk. Using smarter, tamperevident containers.

Voluntary
November 2001
9000 members
Canada has a program very similar
to C-TPAT named FAST – Free and
Secure Trade.
C-TPAT
• According to US Customs and
Border Protection Agency, the
benefits of participating in C-TPAT
could include:
– Playing an active role in the war
against terrorism
– A reduced number of CBP
inspections.
– Priority processing for CBP
inspections.
Orlando International Airport
• No staffing of doors for employee
entrance to baggage claim areas
• Guns smuggled into planes by employees
• “no requirement for us to staff those
doors” OIA Spokesperson; TSA – “not my
job!”
• Identified as security issues in 2004
• 2006 – ½ of TSA Screeners failed test
that measured how well employees could
identify explosives, guns and other
weapons on the scanner – but can
identify bottles of mouthwash and
toothpaste
