OM 300 Exam 1 - Northam | The University of Alabama | UPDATED
Questions with 100% Verified Answers
Question: Part 1: Excel in OM
Answer:
N/a
Question: What is a model?
Answer:
A purposeful representation of key elements of objects or systems and the relationships among them; provides
abstract representation of something real
Question: What should be omitted in a model?
Answer:
Useless data
Question: What are the four different types of models?
Answer:
1. Mental Models 2. Visual Models 3. Physical Models 4. Mathematical Models
Question: What is mental model?
Answer:
Models that tell you what to do; example: traffic light, ski slope difficulty indicator
Question: What is a visual model?
Answer:
Graphic model; example: maps and flowcharts
Question: What is a physical model?
Answer:
A 3D representation, usually intended for larger objects to scale; example: model of a cruise ship
Question: What is mathematical model?
Answer:
Model that shows a quantitative representation of a real problem. This is really the only model that we will be
using; example: weather forecasts, spreadsheet, balance sheet etc.
, Question: What are the two types of mathematical models?
Answer:
1. Algebraic: Equations that represent relationships between quantities in a system 2. Spreadsheet: Way of
implementing mathematical models; usually more visually appealing
Question: What are the ABCs of spreadsheet modeling?
Answer:
A - All work must B - Be: C - Correct - Correct Numerical Answers D - Documented - Descriptive Labels,
Comments, Formatting E - Engineered - Design is important; draw on paper first F - Flexible - Accurate results
if input changes; formulas contain cell references and NOT hard coded numerical values
Question: What is an Influence Chart?
Answer:
A simple diagram to show the relationships between inputs and outputs in a spreadsheet model; typically a
simple hand-drawn model
Question: Why do we use influence charts?
Answer:
To define the problem structure, ignore all numerical data, identify the main elements of the model, and define
the assumptions of the model
Question: Chapter 1: Operations & Productivity
Answer:
N/a
Question: What is Operations Management (OM)?
Answer:
Production activities that go on in an organization that create value; turns inputs into outputs
Question: What is production?
