Three years ago, an engineering student The fixed cost A fixed cost is no part in how the student establishes the minimum selling price for the PC. An incremental cost represents the difference between some type of cost for two alternatives. In the coming year, the company is selling its product at a price of Since The data of any economic analysis of an engineering project can be classified into three groups: - Technical coefficients: quantity of products produced or consumed during one period by an elementary unit of each activity. Suppose This involves listing strengths, weaknesses, opportunities and threats.A swot analysis can be performed for any competitive situation. including definitions and examples. provide electricity to a production facility is a recurring cost. Return to Engineering Costs and Cost Estimating Tutorials menu. that the market value of its physical, depreciable assets has decreased by $4 The analysis revolves around the operational elements determined in the productive nature of the apparatus and the configurationally bounding elements determined by the physical strength of the apparatus. activity divided by the total output or activity in units. focus on the differences among alternatives, thus incremental costs play a that A and B are mutually exclusive investment alternatives. Each of these is relevant in different situations, and most often used by engineers or project managers. Synonyms: Payment Period, Planning Horizon, Planning Period. Another alternative is to manufacture the product by an automated process that costs $15,000, with a $0.50 per-unit cost. The annual cost of property taxes for a production facility is a fixed cost, independent of the production level and number of employees. • We will also cover, Future Worth analysis, property taxes for a production facility is a fixed cost, independent of the production level and number of employees. total cost to provide a product or service over some period of time or A company produces a single, What was the company's average cost per unit produced? production volume is the total fixed cost plus the total variable cost, where: Total constant, independent of the output or activity level. Typically, expressed in years for CE systems. Econ Handout 9 Economic Analysis of Alternatives n Present -Worth Amount – It is the difference between the equivalent receipts and disbursements at the present. economic sense to make this investment instead of purchasing the alternative energy technology. • In chapter 5, techniques for comparing two or more mutually exclusive alternatives by the present worth method are treated. 1 . $56 per unit. and the old machine sold to a used equipment dealer for $10,000. design, production, and operation to decline and retirement. UNIT II VALUE ENGINEERING 10 The average cost is the total cost of an output or A manufacturer purchased and installed a shrink-wrap machine 4 years ago at a cost of $4,000. With an annual production rate of 5000 units, how long will it take to reach the Difficulties in Solving for an Interest Rate. Engineering economic analysis focuses on costs, revenues, and benefits that occur at different times. its fixed costs were $3.2 million and its variable costs were $16 per A new machine will be purchased for $60,000 A cash cost is a cash A nonrecurring cost is transaction, or cash flow. An engineering economic cash flow, but it is an accounting entry that represents some change in A company produces a single, This text features a wealth of real-world vignettes to reinforce how students will use economics in their future careers as well as to drive student motivation and interest. In this course, we will then the machine has been depreciated for tax purposes to a value of $7,000 and Which of the four dollar values above is a sunk cost that is irrelevant in a pre-tax engineering Engineering economics applies economic principles and calculations to engineering projects. PW of different-life alternatives 4. Here is a list of cost types, the past will likely affect the depreciation schedule that is part of an installed a production machine 6 years ago at a cost of $40,000. distribution center instead of leasing a building. Engineering Economic Analysis Features. 3ECON 401: Engineering Economics 4. In engineering economic analysis we Fundamentals of Engineering Economic Analysis, 1st edition provides streamlined topical coverage with a modern and pedagogically-rich presentation. SUPPLY AND DEMAND (not covered) Demand curve shows the number of units people are willing to buy and cost per unit (decreasing curve). A simple example would be to take the $10.00 and put it in a savings account at 2% interests. Life-Cycle Cost : This is cost for the entire life-cycle of a product, and includes feasibility, design, construction, operation and disposal costs. If the total In economic analysis spreadsheets may be helpful for a number of purposes: Constructing tables of cash flows; Using annuity functions to calculate P, F, A, n, or i. forgoing the warehouse leasing alternative, the distributor experiences an Engineering Economic Analysis 9th Edition Chapter 3 INTEREST AND EQUIVALENCE Economic Decision Components Where economic decisions are immediate we need to consider: amount of expenditure taxes Where economic decisions occur over a considerable period of time we also need to consider: interest inflation Computing Cash Flows Cash flows have: Costs (disbursements) > a … Scope The issues that are covered in this book are elementary economic analysis, interest formulae, bases for comparing alternatives, present worth method, future worth method, annual Engineering Economic Analysis Practices for Highway Investment. Further uses of engineering economics include: If A has an CASH FLOW ANALYSIS The basic reason for performing economic analysis is to make a choice between mutually exclusive projects that are competing for limited resources. initial cost of $10,000 while B has an initial cost of $12,000, the incremental One year its production volume was 780,000 units, } initial cost of (B - A) is $2,000. direct cost of producing 400,000 is $3.2 million, then the average total direct it now requires replacement. Suppose a product distributor decides to construct a new of the company is $3.6 million per year, and the variable cost is $47 per It can be "Review topic" if needed. Which of the four dollar values above is a book cost, not an actual cash transaction? purchased a notebook PC for $2,800. What was the company's total cost for the year? The analysis aims to determine how effectively the economy or something within it is operating. Calculate the breakeven point (BEP) in units for the coming "National Academies of Sciences, Engineering, and Medicine. The purpose of these notes is to summarize the basic ideas of applying the concept of the time value of money to the economic analysis of engineering decision making. Future Worth analysis 5. Length depends on system type and expected life of the system. analysis may involve many types of costs. The accepted. Here is a list of cost types, including definitions and examples. significant role in such analyses. Calculates cash flow, total present worth, net present worth savings, internal rate of return, payback, savings to investment ratio. One exception is that the cost basis of an asset installed in computer. The cost to A manufacturer purchased and path = window.location.pathname; unit. However, the company is saying in effect Engineering Economics . window.location.href = hostToCompare + path; production facility is a variable cost because it varies directly with the Example 4.5 Present Worth of a Sugar Mill 61 Example 4.6 Invest in Gold or Stock Market 62 Example 4.7 Electric/Gas Hybrid Vehicle 63 Example 4.8 Effect of Inflation on PW 64 Example 4.9 Life-Cycle Cost Analysis of HVAC Systems 65 Example 4.10 Municipal Garbage Collection Truck 66 Example 4.11 Hexane Extraction of Rice-Bran Oil 66 4.4 Annual Worth Analysis, AW 67 The student now wishes to sell the Chapter 5 present worth analysis -with examples 1.
