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.
HW 5 Q6
Solidtronic Incorporated an original equipment manufacturer (OEM), has a product specification of 71 ± 5 (i.e., T [the target value] = 71). The cost for warranty services (when the quality characteristic, x. is either 66 or 76) is estimated as $600 per unit.
What is the value of k, the cost coefficient in the Taguchi quality loss function (QLF) for this situation?

It is one that fits the intended customer’s requirements. Impliedly, the product should possess attributes that enables it meet the customer’s requirement or specification. Now, in identifiably distinctive manner, differentiate quality control from the others or quality assurance. ii) Briefly define hazard, when uncertainty is defined as being a situation in which the determination of risk factors is not possible. It is difficult therefore to calculate the effect of uncertainty upon the tender, and a discussion of uncertainty is out of place here.

- Summarize and create conclusion to this statement: We all know that the first factor that the customer is looking for before buying the product is the quality of the goods. If the company decided to use low-cost materials in order to reduce the total cost of goods sold and for them to lift up the net income, then it will only result to a negative outcome. A company's overall strength can be maintained by focusing on quality. It has a wide range of effects on a business. When a company tries to save money by using low-cost raw materials, it may end up producing low-quality products with defects and errors. The cost of poor quality includes not only costs associated with product defects, but also costs associated with company procedures, practices, or operations that result in defects or errors. Poor quality can also harm your brand, impair consumer relationships, and add significant operational and financial costs.arrow_forwardThe measurement of 85 automotive cables gave an arithmetic mean of the inner diameters of 3.51 mm and a standard deviation of 0.02 mm.The value required by the manufacturer is 3.5 upper/lower tolerance +0.04/ -0.12It is requested : a. Calculate the capability coefficients Cp, Cpk and state whether or not the machine is capable of producing compliant parts, i.e. whether or not the data dispersion is well centred. If applicable, calculate the adjustment coefficient Cr.b. If scrap is obtained, state whether it is recoverable or non-recoverable and calculate the percentage of scrap.c. Plot the limits of the tolerance field and the distribution of the measured data (using mean and standard deviation).arrow_forwardIn the 1950s, management consultant Dr William Edwards Deming developed a method ofidentifying why some products or processes don't work to achieve the quality objectives. Hisapproach of Plan-Do-Check-Act (PDCA) model has since become a popular strategy tool, usedby many different types of organizations. It allows them to formulate theories about what needsto change, and then test them in a "continuous excellence loop." Explain the PDCA concept incontinuous improvement in designing quality management programme towards continuousbusiness process improvements.arrow_forward
