The Tinkan Company produces one-pound cans for the Canadian salmon industry. Each year the salmon spawn during a 24-hour period and must be canned immediately. Tinkan has the following agreement with the salmon industry. The company can deliver as many cans as it chooses. Then the salmon are caught. For each can by which Tinkan falls short of the salmon industrys needs, the company pays the industry a 2 penalty. Cans cost Tinkan 1 to produce and are sold by Tinkan for 2 per can. If any cans are left over, they are returned to Tinkan and the company reimburses the industry 2 for each extra can. These extra cans are put in storage for next year. Each year a can is held in storage, a carrying cost equal to 20% of the cans production cost is incurred. It is well known that the number of salmon harvested during a year is strongly related to the number of salmon harvested the previous year. In fact, using past data, Tinkan estimates that the harvest size in year t, Ht (measured in the number of cans required), is related to the harvest size in the previous year, Ht1, by the equation Ht = Ht1et where et is normally distributed with mean 1.02 and standard deviation 0.10. Tinkan plans to use the following production strategy. For some value of x, it produces enough cans at the beginning of year t to bring its inventory up to x+Ht, where Ht is the predicted harvest size in year t. Then it delivers these cans to the salmon industry. For example, if it uses x = 100,000, the predicted harvest size is 500,000 cans, and 80,000 cans are already in inventory, then Tinkan produces and delivers 520,000 cans. Given that the harvest size for the previous year was 550,000 cans, use simulation to help Tinkan develop a production strategy that maximizes its expected profit over the next 20 years. Assume that the company begins year 1 with an initial inventory of 300,000 cans.

5. The manager of a fast-food restaurant featuring hamburgers is adding salads to the menu. If they choose to include a salad bar (i.e., the MAKE option), it will cost $14,000 in annual fixed costs for the leased equipment and added employee, and $1 per salad variable cost. If they choose to have pre-made salads (i.e., the BUY option), it will cost $3 per salad. The manager expects to sell 7,500 salads per year. What is the make or buy quantity (i.e., the breakeven point between making vs. buying)?

Three methods can be used for producing heat sensors for high-temperature furnaces. Method A will have a fixed cost of $140,000 per year and a production cost of $62 per part. Method B will have a fixed cost of $210,000 per year and a production cost of $28 per part. Method C will require the purchase of equipment costing $500,000. It will have a life of five years and a 25% of first cost salvage value. The production cost will be $53 per part. At an interest rate of 10% per year, determine the breakeven annual production rate between the two lowest cost methods.
Janice Brown is employed by Starport Hardware Limited as a store clerk. One day she was inthe store arranging some items on a top shelf, the ladder she was standing on collapsed and shesuffered a broken arm and leg. The doctor told her that she had to a major surgery and it wouldtake approximately three months for her to heal enough to return to work.

She is unsureabout the concepts and seeks your help to answer certain questions. A. Explain the concept ‘workers compensation’ B. Discuss the main objectives of workers compensation.C. Explain to Janice how workers compensation can assist her.D. Self-insurance is connected to workers compensation. State what isself -insurance and outline three advantages of it.
The Gorman Manufacturing Company must decide whether to manufacture a component part at its Milan, Michigan, plant or purchase the component part from a supplier. The resulting profit is dependent on the demand for the product. The following payoff table shows the projected profit (in thousands of dollars): State of Nature Low Demand Medium Demand High Demand Decision Alternative s 1 s 2 s 3 Manufacture, d 1 -20 40 100 Purchase, d 2 10 45 70 The state-of-nature probabilities are P(s1) = 0.25, P(s2) = 0.25, and P(s3) = 0.50 (a) Use a decision tree to recommend a decision. (b) Use EVPI to determine whether Gorman should attempt to obtain a better estimate of demand. Enter your answer in thousands dollars. For example, an answer of $200 thousands should be entered as 200,000. Gorman attempt to obtain a better estimate of demand, as the additional information could be worth up to $ for Gorman.
