You are a telecommunications guru and love to help individuals and businesses. Assume that dial-up, cable, DSL, T3 line, and satellite links to the Internet are available everywhere unless the particular scenario indicates otherwise. Consider the following scenarios and suggest the best overall type of link (consider communication speed, cost, and any other factor you believe is relevant). Each scenario is independent of the others. For each scenario, explain why you selected the option. PLEASE different answer from the previously posted if possible Thank you.

a. An author works at home writing articles for a magazine. Once per week she must transmit an article to her editor. She rarely uses the link for any other purpose.

b. A large company maintains its own website for online catalogs and purchase transactions by its customers. Hundreds of customers visit the sites daily and make purchases.

c. A small business uses the Internet for daily research. Owners have heard that some links are shared by other subscribers in the same area, which might slow down the connection or even pose security threats. Thus, they would like to avoid such a service. They do need a speed of at least 200 Kbps.

d. A farm in New Mexico needs a link of at least 200 Kbps. People on the farm can receive television signals only through antennas. The closest telephone central office is 12 miles away.

e. An Internet service provider specializes in hosting websites of small businesses.

f. A cruise ship wants to provide Internet service to vacationers on the third deck. The ship cruises in the Caribbean. The link’s speed must be at least 250 Kbps.

  1. a furniture company that manufactures traditional Japanese furniture. The final assembly process is performed manually by 10 workers. Two main components C-I and C-II are required and fabricated with an equipment, TJ, on which setup times for the two components are 15 and 30 minutes, respectively, whenever switching manufacturing between C-I and C-II. The processing times for each unit of the two components are 4 and 1 minutes, respectively. One C-I and four C-II are required for each item of Furniture-A.
  1. Furniture-A is very popular. Customers have to wait months in the order queue. F-Kyoto now runs batch sizes of 600 and 2400 for C-I and C-II, respectively. What is the capacity of TJ?
  2. 10 minutes are required to assemble a Furniture-A. What is the capacity of assembly? Which is the bottleneck?
  1. Customers are unhappy because they have to wait long periods to obtain a Furniture-A. The company comes to Doshisha Business School and hires you as a part-time consultant to improve the process capacity of producing items of Furniture-A. You cannot hire more workers because the current 10 workers are specialists with long-year experiences. It is difficult to find additional workers with those high skills. To match TJ with assembly process, you use the following “batch size formula” you learnt from Professor Yin’s course to decide the appropriate batch size for C-I and C-II.

But you are surprised that the answer is a negative number of -6.42857, gotten by (10/10 * 45)/(1-10/10 *8). Why does this formula not function?

You are a consultant, located in Gunnedah. One of your clients is a local farmer who has five possible alternative crops to grow in her property next season and she needs to decide if to buy insurance is appropriate. You decided to evaluate the five possible crops using an Expected Utility Model (EUM) approach. In an interview with the farmer, you were able to collect this information about her utility at different income levels (in AUD’000):

During the interview, Amber mentioned she is considering growing barley, cotton, sorghum, sunflower or wheat, given the characteristics of her farm. Note that it is not possible to combine crops, so only one must be chosen. Based on weather forecasts and market information you are able to create the following Payoff Table of the Expected Profit:

7. (All students) The government is offering an insurance that can take away the weather risk that could be faced in the worst two states of nature, giving the farmer an equivalent to the second best state of nature. If the insurance cost is constant per hectare = $50 (in AUD’000), should the farmer buy the government insurance? If yes, which crop should the farmer choose? (15 Marks)
