9. Engineering Economics and Decision Making
9
Engineering economy involves formulating, estimating
and evaluating the expected outcomes of alternatives
designed to accomplish a defined purpose.
Mathematical techniques are used to simplify economic
evaluation of alternative and these techniques are equally
good for individual, business or government projects.
Thus this course may also offer you an economic analysis tool
for making decisions such as car purchase, house purchase,
and major purchase on credit card etc

10. Engineering Economics and Decision Making
10
Decision Making is broad topic.
It’s is a major aspect of every
human existence.We are
surrounded by sea of problems
which may be classified depending
on difficulty level as given below;
1. Simple Problems
2. Intermediate Problems
3. Complex Problems
The Decision Making Process
1. Irrational Decision making
2. Rational Decision making
Rational Decision making process

11. Engineering Costs
11
Fixed Cost: These constant or unchanging regardless of the level of
output or activity.
Variable Costs: These are not constant and depends in level of out or
activity.
Marginal Costs: It is the variable cost for one more unit.
Average Costs: It is total cost divided by number of units

12. Engineering Costs
12
Sunk Cost: A sunk cost is money already spent as a result of past
decision.
Opportunity cost: An opportunity cost is associated with using a
resource in one activity instead of another.
Recurring and Nonrecurring costs
Recurring costs refers to any expense that is know and anticipated and that
occurs at regular interval.
Nonrecurring costs are one-of-a-kind expenses that occur at irregular
intervals and thus are sometimes difficult to plan for or anticipate from a
budgeting perspective.

13. Cost Estimating
13
Types of Estimates
1. Rough Estimate
2. Semi-detailed estimate
3. Detailed estimate
Estimating Models
1. Per unit model
2. Segmenting model
3. Cost indexes
4. Power-sizing model
5. Triangulation
6. Improvement and learning curve

14. Cash Flow Diagram (CFD)
14
Cash flow diagrams visually represent income and expenses over some
time interval.
It is graphical representation of cash flows drawn on the y-axis and a time
scale along x-axis.

15. Cash Flow Diagram (CFD)
15
Categories of Cash Flows
The expenses and receipts due to engineering projects usually fall into one
of the following categories:
First cost: expense to build or to buy and install
Operations and maintenance (O&M): annual expense, such as electricity,
labor, and minor repairs
Salvage value: receipt at project termination for sale or transfer of the
equipment (can be a salvage cost)
Revenues: annual receipts due to sale of products or services
Overhaul: major capital expenditure that occurs during the asset’s life
Revenue

16. Interest
16
1. Simple interest
Simple interest is computed only on original sum (principal), not on prior
interest earned and left in the account.
A bank account, for example, may have its simple interest every year: in this
case, an account with $1000 initial principal and 20% interest per year
would have a balance of $1200 at the end of the first year, $1400 at the end
of the second year, and so on.
2. Compound Interest
Compound interest arises when interest is added to the principal of a
deposit or loan, so that, from that moment on, the interest that has been
added also earns interest.This addition of interest to the principal is
called compounding.
A bank account, for example, may have its interest compounded every year:
in this case, an account with $1000 initial principal and 20% interest per
year would have a balance of $1200 at the end of the first year, $1440 at
the end of the second year, and so on.

Depreciation is a decrease in value of an asset each year:
a decrease in market value
a decrease in the value to the owner
Important reasons for depreciation include
deterioration
obsolescence
