The document discusses various techniques for economic analysis of alternatives using present worth analysis:
1. Present worth analysis requires converting all cash flows to their present value using the minimum attractive rate of return. Costs are assigned a negative sign and revenues a positive sign.
2. For mutually exclusive alternatives, the alternative with the highest positive present worth is selected. For independent projects, all alternatives with a positive present worth are selected.
3. When alternatives have unequal lives, they must be compared over an equal period of time using either the least common multiple of lives or a specified study period.
4. Capitalized cost analysis is used to evaluate alternatives that have an extremely long useful life and is calculated as the annual
Self-energizing brakes use the force of a rotating drum to increase brake pressure. When the brakes are applied while moving forward, the primary shoe moves in the direction of drum rotation, pulling the linked secondary shoe around the anchor pin to force both shoes tighter against the drum. Similarly, when reversing, the secondary shoe moves clockwise to push the primary shoe tighter against the anchor pin, increasing brake pressure.

Here are the steps to design and draw a flywheel for a four stroke four cylinder 133 kW engine running at 375 rpm with a diameter not exceeding 1 m:
Given:
Power of engine, P = 133 kW = 133000 W
Number of cylinders, n = 4
Speed of engine, N = 375 rpm
Maximum diameter, Dmax = 1 m
Step 1) Calculate the mean effective pressure (p):
p = (2*P)/(n*π*D^2*N)
p = (2*133000)/(4*π*(0.5)^2*375) = 7 bar
Step 2) Calculate the mass moment of inertia (I) required:

The document discusses various graphical synthesis methods for mechanism design including:
1) Determining the type and number of links required to generate a specified motion.
2) Using two or three positions of a coupler link to locate fixed pivots for 4-bar and 6-bar linkages.
3) Adding an extra link to an non-Grashof mechanism to satisfy the Grashof condition.
4) Specifying fixed pivots and positions to solve for a linkage that generates the required motion.
5) Designing quick-return mechanisms using the toggle positions of a crank-rocker.
Annual worth (AW) analysis allows engineers to evaluate project alternatives over multiple life cycles by converting all cash flows to equivalent uniform annual amounts at a discount rate. Key aspects of AW analysis include calculating the capital recovery rate to determine the equivalent annual cost of initial investments, and summing equivalent annual cash flows for operating, maintenance, and replacement costs over the life of each alternative. Life-cycle cost analysis takes a broader perspective by considering all costs from project inception through disposal or replacement.
This document summarizes key concepts in engineering economy analysis including:
1. Present worth analysis which converts cash flows to present value using a discount rate to evaluate alternatives of equal or different lifetimes.
2. Alternatives can be mutually exclusive, competing directly, or independent projects that are evaluated separately.
3. Equal service lifetimes are achieved by using the least common multiple of lifetimes or a specified study period.
4. Future worth analysis follows the same process as present worth but calculates future rather than present values.
5. Capitalized cost analysis treats projects as having infinite lifetimes by calculating the perpetual equivalent uniform annual cash flow.

This document summarizes finite element analyses performed on a rail crane platform and wind turbine. For the rail crane, static structural analyses were conducted to analyze stress and deformation on wheels under different loading and contact conditions. A thermal analysis determined temperature distribution and additional stresses on wheels over time. For the wind turbine, static loads representing real forces were applied to a blade, and modal and harmonic response analyses examined the structure's natural frequencies and response to vibrational loads.
This document discusses the cam jump phenomenon in cam and follower mechanisms. It defines cam jump as occurring under high speeds when the unbalanced forces during negative acceleration exceed the spring force, causing the cam and follower to separate. It presents the equations of motion for a follower under the forces of inertia, spring, and cam. It identifies the critical speed as when the force on the follower is zero, indicating no contact. Above this speed, hammering noises occur due to cam jump. The document recommends increasing preload and spring stiffness to avoid cam jump to some extent.

Engineering economy involves applying economic principles to engineering project decisions. It allows engineers to evaluate design alternatives and justify projects based on both technical and financial factors. Some key applications of engineering economy include selecting equipment, determining whether to purchase or lease assets, and evaluating public infrastructure projects based on costs, benefits, and property value impacts. The rational decision-making process in engineering economy helps engineers objectively analyze alternatives and choose optimal solutions for both business and non-profit organizations.
1) The document discusses the role of engineering economics in decision making for engineering projects. Engineering economics involves evaluating the costs and benefits of alternatives and selecting the most economically viable option.
2) Key considerations in engineering economic analysis include present worth, future worth, payback period, rate of return, and benefit-cost ratio. Engineers must analyze project alternatives using these measures to determine the best investment.
3) Economics is an important part of engineering, as the economic viability of design options must be considered along with technical factors. Engineering economics analysis helps engineers optimize design decisions and investment of funds.
In this presentation,I have stated some of the important topics and concepts of "Economic engineering". which can help an individual to enhance his skills in Economic engineering .
Introduction to Design of thermal systems and optimization Sujit Yadav
This document provides an introduction to the design of thermal systems. It begins by defining engineering and noting that systems design is the focus of the course. Thermal systems are complex due to fluid flow and heat transfer mechanisms. Examples of thermal systems include manufacturing processes like continuous casting, materials processing like plastic extrusion, energy systems like solar and nuclear, cooling systems for electronics, environmental systems like power plant cooling towers, transportation systems for aircraft propulsion, fluid flow networks, and heat transfer equipment. The analysis of thermal systems involves considerations like time-dependence, multidimensionality, nonlinear effects, complex geometries, coupled phenomena, and variable properties.
This document provides an overview of engineering economics and introduces some key concepts. It begins by defining economics as the study of how individuals and organizations allocate scarce resources. It then explains why engineering economy is important, as engineers must make economic decisions when selecting between alternatives. The main points covered include:
- Performing engineering economy studies involves formulating problems, estimating costs and outcomes of alternatives, and evaluating the best option.
- Basic concepts like utility, various costs (fixed, variable, average, marginal), opportunity costs, and life-cycle costs are introduced.
- Time value of money concepts like present and future worth will be covered in more detail later.
Production engineering is a combination of manufacturing technology, engineering sciences with management science. ... The goal is to accomplish the production process in the smoothest, most-judicious and most-economic way.
This document outlines the syllabus for an engineering economic analysis course. It provides information on instructors, required text, course description, grading, policies, and tentative course outline. The course will cover concepts like time value of money, analysis of engineering decisions, and dealing with uncertainty. Grading will include exams, quizzes, and class participation. Policies address attendance, makeups, and classroom behavior.
The document provides an introduction to engineering economics. It defines economics and engineering economics, noting that engineering economics deals with the analysis and evaluation of factors that will affect the economic success of engineering projects. It discusses key concepts from economics used in engineering economics, such as scarcity, opportunity cost, demand and supply. It also outlines the basic guidelines for engineering economic analysis, including developing alternatives, focusing on differences among alternatives, using consistent and common units of measurement, and considering uncertainty. The document emphasizes that engineering economics is important for engineering decision-making involving questions about project priorities, designs, and economic worth.
This document discusses decision making and professional ethics in engineering economic decisions. It begins by classifying problems as simple, intermediate, or complex. The rational decision making process involves 9 steps: recognizing the problem, setting goals/objectives, gathering data, identifying alternatives, selecting evaluation criteria, constructing a model, predicting outcomes, choosing the best alternative, and auditing results. Professional ethics are important to consider, as codes of ethics guide engineers' decisions. Situations involving safety compromises or unfair advantages can raise ethical issues.

Safety, conflicts of interest, and maintenance are some areas where ethics intersect with economic decisions. The Bhopal disaster is provided as an example of how compromising safety for cost savings can have tragic consequences.
This report discusses and talks about the engineering economic analysis material and
introduces the student to cost analysis scenarios in which a typical working engineer
might be involved. It outlines some of the many and varied cost and economic
analyses to which beginning, as well as journeyman, engineers are exposed. Effective
analysis of product and project costs and the ability to implement cost control
measures are two sides of the same coin. Most business economic decisions involve
the element of time, however, and it is thus necessary to consider factors such as
interest, the time value of money, and depreciation of equipment. The effect of
inflation (or deflation) on the rate of return for investment depends on how the
future returns respond. Larger investments are analyzed by evaluating the rate of
return. Like other decision-making processes, the decision matrix is a valuable tool to
assist in evaluating the various alternatives, And so report explained and I mentioned
a very important part or let's say element in engineering economic witch is interested I
explained it briefly within its formula and figures and its type and ect...finally my aim
is showing effect and importance and actions of the (Interest) in economy field.

It discusses the key components of a DPR including an executive summary, project details, feasibility study, technical aspects, costs, permits required, and developing a financial model. It also outlines aspects investors look for in a business plan such as market opportunity, solution, team, financial projections, and risks. The document serves as a case study for how to develop a DPR and secure funding by presenting to investors for a wind-based power generation project.
This document provides an introduction to the concepts of engineering economics and engineering. It defines engineering economics as the application of economic principles to the evaluation of design and engineering alternatives. Some key points covered include:
- Engineering economics involves formulating, estimating, and evaluating economic outcomes of alternatives using mathematical relationships to compare cash flows. It must deal with risk and uncertainty.
- The time value of money is a central concept, dealing with how the value of money changes over time due to factors like investment opportunities and inflation. Interest rates and discount rates are used to relate amounts over different time periods.
- Engineering economics helps engineers make good decisions by assessing alternatives in economic terms and identifying the most efficient solution based on costs, benefits
- This document provides information about Math 22 - Linear Algebra and its Applications, including lecture details, homework assignments, and upcoming exam schedules.
- It reviews the row reduction algorithm and solving systems of linear equations. Key steps in the forward and backward phases of row reduction are outlined.
- Vectors and linear combinations are introduced. Properties of vectors in Rn are defined, including vector addition and scalar multiplication. The span of vectors is defined as the set of all possible linear combinations.
This document discusses models for replacing equipment and analyzing maintenance costs. It introduces key concepts like preventative maintenance, breakdown maintenance, and determining the economic life of assets. Preventative maintenance aims to detect potential failures early and make minor repairs, while breakdown maintenance occurs after equipment fails. Determining the optimal level of preventative maintenance balances these costs. The economic life of an asset is the time when total costs are minimized, balancing initial capital costs and increasing operating/maintenance costs over time. The document provides examples of calculating economic life under different interest rates.
This document discusses the time value of money and compound interest. It introduces simple and compound interest, and provides formulas for calculating both. Compound interest allows interest to earn interest over time, providing higher returns compared to simple interest. The time value of money is important when evaluating financial decisions involving cash flows over different time periods. Interest rates are used to quantify the time value of money and allow present and future cash flows to be compared. Examples are provided to demonstrate calculating interest using simple and compound formulas.
This document contains technical information about interest formulas and calculations from Contemporary Engineering Economics, 4th edition. It includes examples of using present worth factors, uniform series factors, and gradient factors to calculate equivalent present values for various cash flow patterns including linear, declining, and geometric gradients. It also discusses unconventional calculations for cash flows with missing payments, varying interest rates over time, and payments occurring at irregular intervals.
The document discusses interest formulas for equal payment series, gradient series, and geometric gradient series used in engineering economics. It provides examples of using these formulas to calculate present worth, future worth, payment amounts, and time required to reach a certain future value for uniform, declining, and increasing payment scenarios. Worked examples analyze loan repayment, retirement savings plans, and costs of equipment repair or replacement under different interest rate assumptions.
1) The document contains examples and explanations of present worth factors, equivalent cash flows, and unconventional calculations involving compound interest from the 4th edition of Contemporary Engineering Economics.
2) Various techniques are presented for handling cash flows with missing payments, multiple interest rates, and irregular payment patterns.
3) Examples show how to establish economic equivalence between cash flows, find an unknown interest rate using linear interpolation, and use the goal seek function in spreadsheets.
This document discusses the time value of money and compound interest. It begins with an example of a woman who won the lottery and had to choose between a lump sum payment or annual installments over 20 years. It then covers compound interest, comparing simple and compound interest, and using formulas to calculate future and present value. Several examples are provided to demonstrate calculating interest using these time value of money principles.

ADVICE TO ALL EMPLOYEES
1. Build a home earlier. Be it rural home or urban home. Building a house at 50 is not an achievement. Don't get used to government houses. This comfort is so dangerous. Let all your family have good time in your house.
2. Go home. Don't stick at work all the year. You are not the pillar of your department. If you drop dead today, you will be replaced immediately and operations will continue. Make your family a priority.
3. Don't chase promotions. Master your skills and be excellent at what you do. If they want to promote you, that's fine if they don't, stay positive to your personal.
development.
4. Avoid office or work gossip. Avoid things that tarnish your name or reputation. Don't join the bandwagon that backbites your bosses and colleagues. Stay away from negative gatherings that have only people as their agenda.
5. Don't ever compete with your bosses. You will burn your fingers. Don't compete with your colleagues, you will fry your brain.
6. Ensure you have a side business. Your salary will not sustain your needs in the long run.
7. Save some money. Let it be deducted automatically from your payslip.
8. Borrow a loan to invest in a business or to change a situation not to buy luxury. Buy luxury from your profit.
9. Keep your life,marriage and family private. Let them stay away from your work. This is very important.
10. Be loyal to yourself and believe in your work. Hanging around your boss will alienate you from your colleagues and your boss may finally dump you when he leaves.
11. Retire early. The best way to plan for your exit was when you received the employment letter. The other best time is today. By 40 to 50 be out.
12. Join work welfare and be an active member always. It will help you a lot when any eventuality occurs.
13.Take leave days utilize them by developing yr future home or projects..usually what you do during yr leave days is a reflection of how you'll live after retirement..If it means you spend it all holding a remote control watching series on Zee world, expect nothing different after retirement.
14. Start a project whilst still serving or working. Let your project run whilst at work and if it doesn't do well, start another one till it's running viably. When your project is viably running then retire to manage your business. Most people or pensioners fail in life because they retire to start a project instead of retiring to run a project.
15. Pension money is not for starting a project or buy a stand or build a house but it's money for your upkeep or to maintain yourself in good health. Pension money is not for paying school fees or marrying a young wife but to look after yourself.
16. Always remember, when you retire never be a case study for living a miserable life after retirement but be a role model for colleagues to think of retiring too.
17. Don't retire just because you are finished or you are now a burden to the company and just wait for your day t

Simple Problems
Should I pay cash or use my credit card?
Do I buy a semester parking pass or use the parking meters?
Shall we replace a burned-out motor
Intermediate Problems
Shall I buy or lease my next car?
Which equipment should be selected for a new assembly line?
Which materials should be used as roofing, siding, and structural
support for a newbuilding?
Which printing press should be purchased? A low-cost press requiring
three operators, or a more expensive one needing only two operators?

Complex Problems
They represent a mixture of economic, political, and humanistic elements.
The decision of Mercedes-Benz to build an automobile assembly plant in
Thscaloosa, Alabama, illustrates a complex problem. Beside the economic
aspects, Mercedes-Benz had to consider possible reactions in the American auto
industry.
The annual budget of a corporation-is an allocation of resources, but the budget
process is heavily influenced by noneconomic forces such as power struggles,
geographical balancing, and impact on individuals, programs, and profits.

Key Factors in Selecting Good
Engineering Economic Decisions
Objectives, available resources, time and uncertainty
are the key defining aspects of all
engineering economic decisions
21. 21
Large-Scale Engineering Projects
These typically
require a large sum of investment
can be very risky
take a long time to see the financial outcomes
lead to revenue and cost streams that are difficult to
predict
All the above aspects (and some others not listed here)
point towards the importance of EEA

Types of Strategic Engineering Economic
Decisions in the Manufacturing Sector
Service Improvement
Equipment and Process Selection
Equipment Replacement
New Product and Product Expansion
N.B. Cost reduction or profit maximization can be seen
as generic (common, eventual) objectives
In the most general sense, we have to make decisions
under resource constraints, and in presence of
uncertainty – not only in the EEA context
23. 23
Example 1:
Healthcare Service Improvement
1 Traditional Plan: Patients
visit the service providers
2 New Strategy: Service
providers visit the patients
Which one of the two plans
is more economical? The
answer typically depends on
the type of patients and the
services offered. Examples?
patients
service providers

Example 2:
Equipment and Process Selection
How do you choose between using alternative materials
for an auto body panel?
The choice of material will dictate the manufacturing
process and the associated manufacturing costs
26. 26
Example 4:
New Product and Product Expansion
Shall we build or acquire
a new facility to meet the
increased (increasing
forecasted) demand?
Is it worth spending
money to market a new
product?
27. 27
Example 5: MACH 3 Project
R&D investment: $750 million(!)
Product promotion through
advertising: $300 million(!)
Priced to sell at 35% higher than
the preceding Sensor Excel
model (i.e., about $1.50 extra
per razor)
Question 1: Would consumers
pay $1.50 extra for a shave with
greater smoothness and less
irritation?
Question 2: What happens if the
blade consumption drops more
than 10% – due to the longer
blade life of the new razor?...
28. 28
Example 6: Cost Reduction
Should a company buy
new equipment to
perform an operation that
is now done manually?
Should we spend money
now, in order to save
more money later?
The answer obviously
depends on a number of
factors; can you name
some of these?

The Four Fundamental Principles of
Engineering Economics
1: An instant dollar is worth more than a distant dollar…
2: Only the relative (pair-wise) difference among the
considered alternatives counts…
3: Marginal revenue must exceed marginal cost, in order to
carry out a profitable increase of operations
4: Additional risk is not taken without an expected additional
return of suitable magnitude
Background and explanatory notes will follow later on
33. 33
Principle 2

Summary
The term engineering economic decision refers to any
investment or other decision related to an engineering
project
The five main types of engineering economic decisions are
(1) service improvement, (2) equipment and process
selection, (3) equipment replacement, (4) new product and
product expansion, and (5) cost reduction
The factors of time, resource limitations and uncertainty
are key defining aspects of any investment project
Notice that all listed decision types can be seen and
modeled as a constrained decision (optimization) problem
Question: are you familiar with the basic optimization
concepts? If not, then a brief introduction will be presented
