Roman Numerals and Process - 1682 Words

Chapter 09a Process Capability and Statistical Process Control Review and Discussion Questions 1. The capability index allows for some drifting of the process mean. Discuss what this means in terms of product quality output. When Cpk is larger then 1.33 or 1.5, this means that the mean of the process can drift (up to a limit) while still producing within specifications. This is what is implied by the phrase â€Å"a capable process. 2. Discuss the purposes and differences between the P-charts and X-bar and R charts. P-charts are used to monitor the process for attribute data. These are typically binomial â€Å"go, no-go† data. An example of a P-chart is percent of pieces nonconforming. X-bar charts are used for charting population values†¦show more content†¦Defective average = .04, inspection rate = 50 per hour, cost of inspector = $9 per hour, and repair cost is $10 each. a. | Calculation | Cost per hour | No inspection | .04 * (50) * $10 | $20 | Inspection | | 9 | Therefore, it is cheaper to inspect in this case. b. Cost per unit for inspection = $9/50 = $.18 c. Benefit form the current inspection process is Hourly: cost of no inspection – cost of inspection ($20 - $9 = $11) Per unit: average cost of quality – cost of inspection ((.04)$10 - $.18 = $.22) 2. a. = .889 b. The process is capable of producing the desired quality, but at present it is not capable due to the process center. The process center should be adjusted. 3. a. Ten defectives were found in 10 samples of size 15. = .067 = .0645 UCL = + 1.96 = .067 + 1.96(.0645) = .194 LCL = - 1.96 = .067 - 1.96(.0645) = -.060 zero b. Stop the process and look for the special cause, it is out of statistical control. 4. Defective average = .02, inspection rate = 20 per hour, cost of inspector = $8 per hour, and replacement cost is $25 each. a. | Calculation | Cost per hour | No inspection | .02(20)$25 | $10 | Inspection | | 8 | Therefore, it is cheaper to inspect in this case. b. Cost per unit for inspection = $8/20 =Show MoreRelatedRoman Numeral System1511 Words   |  6 PagesRoman Numeral System Origin: Roman numerals were created some time between 900s and 800s B.C. in ancient Rome.

Congressman Essay Example For Students

Congressman Essay Transformation and inertia are presented as conflicting forces, balanced against one another in a kind of universal tension. The individual changes biologically as well as intellectually and spiritually, but his physical progression from youth to old age follows a path more or less set by nature. Nature itself changes cyclically, but the cycle of the seasonsthe cycle of lifeis repeated over and over. The classics of literature possess permanence in their expression of universal meaning, their relevance to men in all times. They simultaneously have the life-altering power to change a man. Higher laws and divinity are absolute, but they are transformative for the man sensitive to the meanings of nature. Society, institutions, and the traditions of the pastexpressions of the status quoconstitute the major hindrances to change throughout Walden. Technological development is a kind of change, but it prevents the individuals growth by creating a mind-numbing amount of labor and by imposing materialistic values. Thoreau therefore denies that it is true progress. As a manifestation of vigorous nature and of Gods work, Walden is eternal. It transcends time and change. Thoreau writes in The Ponds:. . . of all the characters I have known, perhaps Walden wears best, and best preserves its purity. . . . Though the woodchoppers have laid bare first this shore and then that, and the Irish have built their sties by it, and the railroad has infringed on its border, and the ice-men have skimmed it once, it is itself unchanged, the same water which my youthful eyes fell on; all the change is in me. . . . It is perennially young. . . . Why, here is Walden, the same woodland lake that I discovered so many years ago; where a forest was cut down last winter another is springing up by its shore as lustily as ever; the same thought is welling up to its surface that was then; it is the same liquid joy and happiness to itself and its Maker, ay, and it may be to me. It is the work of a br ave man surely. . . .
