Intro to Operations Flashcards
What are examples of inputs?
Labor, Money, Knowledge
What are examples of outputs?
Goods & Services
Transformation Process: Physical
factory made
Transformation Process: Locational
items from one location to the next
Transformation Process: Exchange
value through RETAIL (i.e. kroger doesn’t grow the corn or can it but they sell it to consumers)
Transformation Process: Physiological
health care (i.e. fitness trainer)
Transformation Process: Psychological
Entertainment
Transformation Process: Informational
communications (i.e. VT teaching students)
Transformation Process: Extraction
Pulling raw material from environment (i.e. mining, logging, etc.)
Operations Management
The design, operation, and improvement of productive systems.
—> How do we optimize decisions to reduce costs?
What are the four primary areas of a firm?
- Finance/Accounting
- Marketing
- Human Resources
- Operations
Just-in-time production
Produce only what you need when you need it
High Degree of Vertical Integration
A business does most of the overall process (not just assembly).
Economies of Scale
As the number of units you produce increases, the cost decreases
What is the advantages & disadvantages of a flexible manufacturing system?
Advantage: no retooling or retraining, easy to reprogram
Disadvantage: EXPENSIVE
Coding wires is an example of what?
Design for maintainability (easier to maintain)
CAE
Computer Aided Engineering
Craft Production
*consumer goods produced by craftsman
The type of production that involves one person making a product from start to finish is:
Craft Production
Property rights, stable government, banking institutions, and the free market approach are all characteristics of which time period?
The Industrial Revolution
Agrarian Society
Industrialized Society
Who invented steam engine power?
James Watt
Adam Smith
- Wrote “Wealth of Nations”
- against government regulated markets
- division of labor
Division of Labor
Breaking jobs into different tasks and assigning each worker a different task using specialized tools, creating specialized labor. Designed to decrease the time it takes to produce goods & services.
Who came up with the idea of interchangeable parts?
Eli Whitney
What is the main idea of interchangeable parts?
Standardized parts- more efficient due to the fact that they were all the same and could be used in any gun
Principles of Scientific Management
- Frederick Taylor
- *Determine best work method and standardize**
- FINANCIAL INCENTIVE & REST BREAKS
Rate Buster
Picking up the pace- not working at the slow speed most/all other workers do
Soldiering
Deliberately slowing the pace of work to convince supervisors you can’t go faster
Time & Motion Study
-Frank & Lillian Gilbreth
took videos to see what the most efficient way of doing things was
RESULTS:
-modern approach to surgery (nurse handing tools)
-dividing up tasks=more efficient
Who created the assembly line?
Henry Ford
When did the Human Relations Movement begin?
1930’s
Hawthorne Studies
- Elton Mayo
- *workers need more than a paycheck for motivation**
- part of human relations movement
When did operations research occur?
Post WW2-1970’s
George Dantzig
*Created linear programming
When was the decline of manufacturing?
1970’s-1980’s
Traditional Mass Production: Who? Focus on? How? Lacking?
Who: US
Focus on: EFFICIENCY & QUANTITY
How: highly specialized, operations turned over to technical specialists
Lacking: Not using strategies for competition
Lean Production: Who? Focus on? How? Lacking?
Who: JAPAN
Focus on: QUALITY & FLEXIBILITY
How: long term strategic goals, can adapt systems to changing technologies
Lacking: N/A
Competitive Benchmarking
*take organization that does well at what you want to do and compare your progress to that
Reverse Engineering
*tearing apart production to study its parts and design
When was the Quality Revolution?
1970’s-1990’s
What are the problems with in-process inventory?
Wasteful/doesn’t fix the problem along the line
Characteristics of TQM (total quality management)
- JIT inventory
- Eliminate waste
Six Sigma
DECREASE variation, INCREASE quality (because you are more in control)
