Federated Electronics, Ltd., manufactures display screensand monitors for computers and televisions, which it sellsto companies around the world. It wants to construct a new warehouse and distribution center in Asia to serve emerg-ing markets there. It has identified potential sites in the port cities of Shanghai, Singapore, Pusan, Kaohsiung, and HongKong and has estimated the possible revenues for each(minus construction costs which are higher in some citieslike Hong Kong). At each site the projected revenues are primarily based on these factors, (1) the economic condi-tions at the port including the projected traffic, infrastruc-ture, labor rates and availability; and expansion and modernization; and (2) the future government situationwhich includes the political stability, fees, tariffs, duties,and trade regulations. Following is a payoff table thatshows the projected revenues (in $ billions) for six years given the four possible combinations for positive and nega-tive port and…

the restaurant value stream map, and recompute the total value-added and non-value-added time and cost given the following new information. The chef's time is valued at $30 per hour, oven operation at $10 per hour, precooking order waiting time at $5 per hour, and postcooking order waiting time at $60 per hour. The $60 estimate reflects the cost of poor quality for a dinner waiting too long that might be delivered to the customer late (and cold). If a restaurant uses iPads to place orders and notify waiters when the customer's order is ready, the time on the order board (now an electronic order board) decreases from five to one minute, and the prepared order wait time decreases from five to four minutes. Round your answer for the total revised time to the nearest whole number and round your answer for the total revised cost to three decimal places. Total Revised Time: minutes Total Revised Cost: $
