A quality engineer has a manufacturing specification (in cm) of 0.25 plus or minus 0.05
Historical data indicates that if the quality characteristic takes on values larger than 0.3 cm or smaller than 0.2 cm, the product fails and a cost of $90 is incurred. Determine the Taguchi Loss Function and estimate the loss for a dimension of 0.15 cm.
An extrusion molding produces pipe with an
outer diameter specification of 15-14mm. A
machine capability study records a mean of
14.56mm and a standard deviation of 0.85.
Calculate Cp and Cpk. Is the machine capable if
1.11 is the minimum acceptable Cp /Cpk set by
the company?
An automobile manufacturer plans to spend one billion dollars to improve the quality of a new model. The manufacturer expects the quality improvement program to eliminate the need for recall and reduce the costs for warranty repairs. The manufacturer’s experience has been, on average, 1.5 recalls for each new model at a cost of $300 per vehicle per recall.
The average cost per recall, if one is needed, is expected to increase by 10% for the new model. Costs for other warranty repairs are expected to decrease from $200 to $80 per unit. Sales of the new model were expected to be 500,000 units without the quality-improvement program. The firm believes that the proposed, well-advertised quality program expected to cost an additional $50 million will increase total sales to 650,000 units. The gross profit per unit on the new model sold is $5,000.

- A six-sigma green belt candidate finds P/T ratio of his gauge as 0.632. The gauge has no bias. He tried improving his gauge precision, but failed to do so. He plans to use averages of repeated measurements in his quality improvement project. How many repeated measurements does he need to make on a part to have a P/T ratio of 0.200 based on the measurement averages?

- A manufacturing company has been inspecting units of output from a process. Each product inspected is evaluated on five criteria’s. If the unit does not meet standards for the criteria it counts as a defect for the unit. Each unit could have a few as zero defects, and as many as five. After inspecting 2,000 units, they discover 33 defects. What is the DPMO measure for this process?

A quality characteristic has a deviation from target of 0.04 with a loss associated with deviation of $40.00. The formula for Taguchi Loss Function is: L(x) = k(x-T)2 (Refer to this spreadsheet for calculations - enter data in the yellow cells only.) What is the value of k.

- A company is reviewing its policy of putting each sub-assembly bought in from outside through a detailed inspection process on delivery. The firm can either inspect or not inspect. The sub-assembly may either come up to the required quality standard (90 % of the time), or fail to do so (10 % of the time). It costs K10 to inspect a sub-assembly and another K10 to put right any defect found at that stage. If the sub-assembly is not inspected and is then found to be faulty at the finished goods stage the cost of rework is K40. Advise the firm what to do?arrow_forwardCost management is used to analyze the cost consequences of different design choices and to measure and report the many aspects of quality, including all of the following except: Multiple Choice Wasted labor or materials. The nature of complaints, warranty costs, and product recalls. The short- and long-term goals of sustainability. The number of service calls. Production breakdowns.arrow_forwardB. Tradeoffs with Quality Costs. Consider the following problem. Banga, Inc. is a startup company engaged in the production of a biofertilizer. It has a sales of 8 million and quality costs of 1.6 million. Consistent with their vision of sustainability by reducing wastes and preventing risks, it is embarking on a major quality improvement program. During the next three years, Banga intends to attack failure costs by increasing its appraisal and prevention costs. The "right" prevention activities will be selected, and appraisal costs will be reduced according the results achieved. For the year 2023, management is considering six specific activities: quality training, process control, product inspection, supplier evaluation, prototype testing, and re-design of two major products. To encourage managers to focus on reducing non- value-added quality costs and select the right activities, a bonus pool is established relating to the reduction of quality costs. The bonus pool is equal to 10…arrow_forward
