- Determine the optimum preventive maintenance frequency for each of the pieces of equipment if breakdown time is normally distributed: (Round "Probability Ratio" to 4 decimal places, and all other answers to 2 decimal places. Negative values should be indicated by a minus sign.) Use Table. Equipment.

A service level failure at the warehouse is an event where a customer's order could not be shipped out in full by the promised shipping time. RoyalTech's ordering system prevents customers from placing orders on products that are not in-stock at the warehouse. Therefore, we can make the statement that "the WMS is guaranteed to show 100% service level at the warehouse." Choose the most appropriate statement in response: O True, because orders will be placed only for products that are available. O False, because service level can never be 100%. O False, because resource constraint or human error may delay the shipping even though inventory is available in the system. O False, because WMS calculations are faulty.A copier is able to operate for an average of 200 hours between repairs, and the mean repair time is two hours. Determine the availability of the copier.
- A manufacturer of microwaves has discovered that male shoppers, on average have lower values for microwave ovens than female shoppers. Additionally, male shoppers attribute almost no extra value to an auto-defrost feature, while female shoppers, on average, value the auto-defrost feature. The manufacturer has determined that men value a simple microwave at $70 and one with autodefrost at $80, while women value a simple microwave at $80 and one with auto-defrost at $150. If there is an equal number of men and women, what pricing strategy will yield the greatest revenue?Y5 Do you think customers might take undue advantage of this guarantee and “stage” service failures to invoke the guarantee? If yes, how could Broadstripe minimize potential cheating on its guarantee?HW1 Q1 Consider the emergency department of a hospital that operates as follows: Upon arrival, patients first wait in line for registration. Then, after registration, patients wait to see a triage nurse who classifies them as either critical or non-critical. After the triage nurse, critical patients go to the emergency care area waiting to be seen by a doctor while non-critical patients go to the routine care area where they wait to see a doctor. It is determined that there are, on average, 20 patients registering or waiting to be registered, 5 patients being seen or waiting to be seen by the triage nurse, 15 critical patients being seen or waiting to be seen by a doctor in the emergency area, and 20 non-critical patients being seen or waiting to be seen by a doctor in the routine care area, Assuming that 20 patients arrive every hour and that 75% of the patients are non-critical, how many minutes does a patient spend on average in the emergency department of the hospital? Average time…

In early planning, BestLine predicted that they could save over 25% of their entire supply chain costs by streamlining and optimizing their practices. One of the areas that had the most promise for savings and efficiency was that of order communication and fulfillment. In the existing system, Bestline’s inventory management department triggered a request to the ordering department. The ordering department then created an order and faxed it out to one of their suppliers. The supplier marked down on the fax what could be fulfilled against the order and would fax it back to BestLine for processing. Over time, this fax-based system proved to be inefficient and error-prone. Faxes were often lost or garbled, and hand-written comments could be very difficult to interpret accurately. As a part of their supply-chain efficiency effort, BestLine decided that they would try to…
