Self-Study Problem 17-2 (Algo) Taguchi Quality Loss Function (QLF) [LO 17-4]Marlon Audio Company manufactures video tapes. The desired speed of its model SF2000 is 6 inches per second. Any deviation fromthis value distorts pitch and tempo, resulting in poor sound quality. The company sets the quality specification to 6 ± 0.29 inch persecond because an average customer is likely to complain and return the tape if the speed is off by more than 0.29 inch per second.The cost per return is $40. The repair cost before the tape is shipped, however, is only $2 per tape.Required:1. Compute L(x) if x is 6.12 inches per second.2. Estimate the tolerance for the firm to minimize its quality-related cost (loss).(Round your answers to 4 decimal places.)1. L(x)2. Toleranceinch

At Gleditsia Triacanthos Company, a certain manufactured part is deemed acceptable if its length is between 12.45 to 12.55 inches. The process is normally distributed with an average of 12.49 inches and a standard deviation of 0.014 inches. a) is the process capable of meeting specifications? b) Does the process meet specifications?
Would a data series that contains values grouped into 10 categories be better displayed as a pie chart or a column chart?
56. The construction of the p chart described in this chapter requires specification of both UCL and LCL levels. Is the LCL meaningful in this context? In particular, what does it mean when an observed value of p is less than the LCL? If only the UCL is used to signal an out-of-control condition, should the calculation of the UCL be modified in any way? (Hint: The definition of the Type 1 error probability, a, will be different. The hypothesis test for determining if the process is in control is one-sided rather than two-sided.)
3/4 roller chain is to transmit power from a 17-tooth drive sprocket to 34-tooth sprocket. Centers of the sprockets are 13 inches apart. Estimate the number of teeth in contact with the chain for the larger sprocket.
9. Two machines are currently in use in a process at the Dennis Kira Mfg. Co. The standards for this process are LSL = .470" and USL = .476". Machine One is currently producing with mean = .474" and standard deviation .0003". Machine Two is currently producing with mean .4745" and standard deviation .0002". Which machine has the higher capability index? Machine One has an index of (round your response to two decimal places). (round your response to two decimal places). Machine Two has an index of Machine (1) (1) Two One has the higher capability index.
C-Spec, Incorporated is attempting to determine whether an existing machine is capable of milling an engine part that has a key specification of 4 ± 0.003 inch. After a trial run on this machine, C-Spec has determined that the machine has a sample mean of 4.001 inches with a standard deviation of 0.002 inch. Calculate the capability index ( Cpk�� ) for this machine. Note: Round your answer to 3 decimal places. Should C-Spec use this machine to produce this part? multiple choice Yes No
Suppose you are analyzing processing times for a machining operation. In your analysis, you found C, = 2.1 and Cpk = 1.28. Given this information, which of the following sigma levels is the highest that you could claim your process is capable of meeting? O 1 sigma O 2 sigma 3 sigma O 4 sigma 5 sigma O 6 sigma
28. A local contractor manufactures the speakers used in telephones. The phone com- pany requires the speakers to ring at a specified noise level (in decibels). An X chart is being designed to monitor this variable. The process of sampling speakers from the line requires hitting the speakers with a fixed-force clapper and measur- ing the decibel level on a meter designed for that purpose. The cost of sampling is $1.25 per speaker. When the process goes out of control, the thickness of the speakers is incorrect. The cost of searching for an assignable cause is estimated to be $50. The cost of operating the process in an out-of-control state is estimated to be $180 per hour. Out of control corresponds to a shift of 2ơ in the decibel level, and the probability that the process shifts out of control in any hour is .03. a. The company uses an X chart based on 3ơ limits and subgroups of size 4. What is its hourly cost? b. What are the optimal values of n and k for this process and the…
Linda Boardman, Inc., an equipment manufacturer in Boston, has submitted a sample cutoff valve to improve your manufacturing process. Your process engineering department has conducted experiments and found that the valve has a mean of 8.00 and a standard deviation of .04. Your desired performance is = 8.0 ± 30, where o = 0.047. Is the following statement true or false? Can Boardman produce the valve within the specified tolerance? (TRUE=yes, it can; FALSE=no, it cannot) O True O False
