The emergency room at a hospital estimates the following requirements for registered nurses (RNs) for the last night shift each week: Sunday–3; Monday–4; Tuesday–2; Wednesday–2; Thursday–3; Friday–6; Saturday–4. Nurses work four consecutive days, then have off three days. Perform cyclical scheduling on the data. (Note that you must identify three-day patterns of minimum requirements.) How many RNs are required? How much extra capacity is required? Your response should be at least 200 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations.

A certain product has been effectively managed in the past, according to its managers. The previous technique used the economic production quantity model, and resulted in an optimum lot size of 100. For this product, setup time is directly proportional to setup cost, and setup time is currently 40 minutes per batch. How much must setup time decline in order for the lot size to fall to 50 units? 25 units? 10 units? Explain how you determined the declines in setup time you calculated.Your response should be at least 200 words in length.

High reliability can be achieved in a product without having high reliability in the component parts. In fact, any reliability target, no matter how high, can be achieved with only mediocre parts, so long as enough of them are present. Explain why this is the case. An example may help with your explanation.Your response should be at least 200 words in length. You are required to use at least your textbook as source material for your response.
