CASE STUDYYou have been assigned the task of making a preliminary recommendationfor the material to be used in the bumper of a new ultra-safe crash-resistantautomobile. It is particularly important that the bumper be able to survivethe energy levels associated with low-velocity crashes, without damage tothe bumper of the automobile. Even more important, for high energy levelsassociated with severe crashes, the bumper should be capable of deformingplastically over large displacements without rupture, thereby dissipatingcrash pulse energy to protect the vehicle occupants. It is anticipated thatthese new vehicles will be used throughout North America, and during allseasons of the year. A 10-year design life is desired. Cost is also anespecially important factor. Propose one or a few candidate materialssuitable for this application. (Specific alloys need not be designated).

Case Study : Neutraizing the Concordia Effect Communication has become crucial in Costa Cruises (the Italian cruise company owned by Carnival Corporation). In recent events, the Costa Concordia keeled over off the Italian coast near the island of Giglio in Tuscany, Italy, in January 2012 and the Costa Allegra was hit by fire and drifts in the Indian Ocean a few weeks later. Captain Schettino's preliminary abandoning of the Costa Concordia as well as his denial to return onboard the sinking ship brought into question the competence of the company crew as well as the effectiveness of recruitment procedures. After a few days of the company stressing that the complete responsibilities of the accident were attributed to the captain, Costa Cruises decided to suspend all social media activities as a sign of respect for the victims and as an attempt to prevent inappropriate comments. However, the lack of disclosure and the distorted information coming from other media aroused contrasting…

Walton Company has measured its quality costs for the past two years. After the company gathers its quality cost data, it summarizes those costs using the four categories shown below: Last Year This Year Prevention costs $ 349,900 $ 617,500 Appraisal costs $ 449,500 $ 523,200 Internal failure costs $ 805,800 $ 520,000 External failure costs $ 1,111,000 $ 673,200 1. Calculate the change in total cost of quality over the two-year period. 2. Is performance trending in a favorable or unfavorable direction?
When do deficiency error and contamination errors occur? What could be the sources of contamination error? Please provide one example and one control suggestion for each source.
FEMA was performed for a seat belt installation process at an automobile assembly plant. Th efollowing three failures modes were identified: (1) Select wrong color seat belt(2) Seat belt bolt were not fully tightened, and (3) Trim cover clip misaligned. The six sigma team rated each of the failure modes for its severity, probability, of occurrence and probability of detection and Severity ratings are 5,9,2, respectively; probabilty of occurence was 4,2,3, respectively; and probability of detection was 3,8,4 respectively. Which of the failure modes should recieve the highest priority for process improvement?
The 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).
380,000 automotive A-Frame brackets are stamped in a year with a complex process involving shearing, forming, stamping, and heat treating.
