An engineer in charge of the design of a plant must choose either a batch or a continuous system. The batch system offers a lower initial outlay but, owing to high labor requirements, exhibits a higher operating cost. The cash flows relevant to this problem have been estimated as follows:

	year 0	year 1-10 (after tax)	discounted cash flow rate of return	net present worth at 12%
batch system	-$20,000	$5,600/year	23%	$14,000
continuous system	-$30,000	$7,650/year	20%	$17,600

Check the values given for the discounted cash flow rate of return and net present worth in the table. If the company requires a minimum rate of return of 15 % which system should be used and why? EXPLAIN BRIEFLY.

Expert Solution

ANS =

# Check the value for dividend discount rate .

- Present value of cashflow = Cashflow / (1+rate) ^n , N= number of years.

- PV of batch cashflow @23% = 5,600 / (1+0.23)^1 + 5,600 / (1.23)^2 + 5,600 / (1.23)^3 + ...till..+5,600 / (1.23)^10 = 21,2755.91 .

- PV of continous system cashflow @20%= 7,650 / (1+0.20)^1 + 7650 / (1.20)^2 + 7650 / (1.20)^3+...till...+ 7650 /(1.20)^10 = 32,072.414.

# Checking the value for NPV @ 12% , here Rate will be 12%

- NPV= PV of all cash inflow - initial investment.

- PV of batch system = 5,600 / (1.12)^1 + 5600 / (1.12)^2 + 5600 / (1.12)^3 +...till ..+ 5600 /(1.12)^10 = 31,641.249

- NPV of Batch system @ 12% = 31,641.249 - 20,000 = 11,641.249

- PV of continous system = 7650 / (1.12)^1 + 7650 / (1.12)^2+ 7650 / (1.12)^3+....till ..+ 7650 /(1.12)^10= 43,224.2

- NPV of continous system @12%= 43,224.2 - 30,000 = 13,224.206.

# Net present worth with 15%.

- PV of batch system @15% = 5,600 /(1.15)^1 + 5600 /(1.15)^2 + 5600 /(1.15)^3+..till..+5600 /(1.15)^10 =28,105.10

- NPV of batch system @ 15% = 28,105.10 - 20,000 = 8,105.10

- PV of continous system= 7650 / (1.15)^1+ 7650 / (1.15)^2 + 7650 / (1.15)^3+..till..+7650/ (1.15)^10=38,395.58

- NPV of continous system = 38,395.58 - 30,000 = 8,395.58.

# Continous system should be choosen as it have Net present worth 290.48 more than the batch system. Continous system is more profitable as it is more profitable project than batch system. Net present worth determine whether present value of future cash inflow is more or less than the initial investment that investor have done. The project should always chosen on the basis of higher net present value as higher the value of NPV the higher will be return to investor.

If the head engineer at the plant decides that measures must be taken to protect health and safety, but the plant manager refuses to approve the measures, what are the obligations of the head engineer?

CASE STUDY In the Appliances Manufacturing Plant, a large number of engineering activities are carried out in a wide range of areas. These activities include design, production of parts, assembly, testing, and quality assurance. Many of the manufacturing processes in the plant are performed using automated technologies and equipment. People also perform some of the manufacturing tasks and the plant employs over 400 workers. The decision on whether people or machines will be used for a particular task is...

Problem 3(a) The average part produced in a certain batch manufacturing plant must be processed through an average of six processes. Twenty (20) new batches of parts are launched each week. Average operation time = 6 min, average setup time = 5hr, average batch size = 25 parts, and average non-operation time per batch = 10hr/ machine. There are 18 machines in the plant. The plant operates an average of 70 production hours per week. The Scrap rate is negligible....

An engineer is responsible for monitoring the quality of a batch of 1000 ohm resistors. To do so, the engineer must accurately measure the resistance of a number of resistors within the batch, selected at random. The results obtained are shown below for samples 1 to 30. 1006, 1006, 978, 965, 988, 973, 1011, 1007, 935, 1045, 1001, 974, 987, 966, 1013, 960, 976, 954, 1004, 975, 1014, 955, 973, 993, 1023, 992, 981, 991, 1013 and 998.

An engineer at a microcircuit factory will inspect a batch of silicon wafers to try to find defects. Assume that there are four defective integrated circuits in a container containing twenty wafers. For that inspection two random wafers are selected. Calculate the probability that: a) None of them have defects b) At least one of the two has no defects.

IAS 16, Property, Plant and Equipment allows companies to choose either the cost model or the revaluation model to measure the carrying amount of property, plant and equipment subsequent to its initial recognition as an asset. Discuss how you should account for revaluation gains and losses when the valuation model is used. In addition, explain how the reversals of the revaluation gains and losses should be reported.

As an engineer you are responsible to in charge to conduct an experiment for this traffic flow analysis: At 2:00 P.M. a traffic accident closes a road to all traffic. At 2:15 P.M. the road is partially opened with a capacity (car departs) of 1,500 veh/h. Finally, the wreckage is removed, and the road is restored to full capacity (car departs) (3,500 veh/h) at 2:35. From 2:00 to 2:35, car arrives at a constant flow of 2,500 veh/h and then...

4. Suppose that you are the engineer in the charge of the gasification section of the Acme Substitute Natural Gas Company. ASNG Co. runs fixed-bed, dry-ash gasifiers. The raw gas is cleaned, shifted, and sent to a methane synthesis unit. Every morning you receive a report from ASNG’s analytical laboratory on the characteristics of the coal that will be fed to the gasifiers during the next day’s operations. One important characteristic is the ash fusion temperature (AFT), i.e., the temperature...

You are an engineer in charge of designing a new generation of elevators for a prospective upgrade to the Empire State Building. Before the state legislature votes on funding for the project, they would like you to prepare a report on the benefits of upgrading the elevators. One of the numbers that they have requested is the time it will take the elevator to go from the ground floor to the 102nd floor observatory. They are unlikely to approve the...
