Textbook Question
Chapter 11.2, Problem 8P
In Example 11.3, if a batch fails to pass inspection, the entire batch is unusable. Change the model so that if a batch fails to pass inspection, it is reworked, and at the end of the rework, its entire yield (the same yield determined in column C) is usable. However, the rework takes 3, 4, or 5 days with respective probabilities 0.2, 0.5, and 0.3. Run the simulation for the modified model and comment on how the results change.

See how sensitive the results in Example 11.2 are to the following changes. For each part, make the change indicated, run the simulation, and comment on any differences between your outputs and the outputs in the example. a. The cost of a new camera is increased to $500. b. The warranty period is decreased to one year. c. The terms of the warranty are changed. If the cam- era fails within one year, the customer gets a new camera for free. However, if the camera fails between 1 year and 1.5 years, the customer pays a pro rata share of the new camera, increasing linearly from 0 to full price. For example, if it fails at 1.2 years, which is 40% of the way from 1 to 1.5, the customer pays 40% of the full price. d. The customer pays $50 up front for an extended warranty. This extends the warranty to three years. This extended warranty is just like the original, so that if the camera fails within three years, the customer gets a new camera for free.

On each bet, the distribution of your net winnings (loss if negative) is highly skewed to the left because there are some possibilities of really large losses but not much upside potential.

Please help me use the following analysis methods. Background Littlefield Technologies (LT) has developed another DSS product. This new model is manufactured using the same process as your previous assignment “Capacity Management at Littlefield Technologies” — neither the process sequence nor process time distributions have changed. Daily customer demand continues to be random, but this time there is no trend. Expected demand remains stable during the entire product life span. Marketing knows demand will end abruptly on Day 268 when a new model is released. LT will again: cease production, retool, and dispose of the obsolete inventory. Marketing discovered that customers would pay higher prices for shorter lead time contracts. LT has been reluctant to quote shorter lead times because current averages have been running longer than they would like. They are wondering if you might be able to shorten lead times and increase marginal revenues.…arrow_forward
