- At the beginning of each week, a machine is in one of four conditions: 1 = excellent; 2 = good; 3 = average; 4 = bad. The weekly revenue earned by a machine in state 1, 2, 3, or 4 is 100, 90, 50, or 10, respectively. After observing the condition of the machine at the beginning of the week, the company has the option, for a cost of 200, of instantaneously replacing the machine with an excellent machine. The quality of the machine deteriorates over time, as shown in the file P10 41.xlsx. Four maintenance policies are under consideration: Policy 1: Never replace a machine. Policy 2: Immediately replace a bad machine. Policy 3: Immediately replace a bad or average machine. Policy 4: Immediately replace a bad, average, or good machine. Simulate each of these policies for 50 weeks (using at least 250 iterations each) to determine the policy that maximizes expected weekly profit. Assume that the machine at the beginning of week 1 is excellent.In order to predict pancakes, John's House of Pancakes uses a weighted moveable average process. It gives a weight of five to the demand in the preceding month, three to request two months ago and one to request three months ago. What is the prediction for August if revenues amounted to 1,000 pancakes in May, 2200 pancakes in June, and 3,000 pancakes in July?John Hospital contains 450 beds. The average occupancy rate is 80% per month. In other words, on average, 80% of the hospital’s beds are occupied by patients. At this level of occupancy, the hospital’s operating costs are P56 per occupied bed per day, assuming a 30-day month. This P56 figures contains both variable and fixed cost components. During the month of June, the hospital’s occupancy rate was only 60%. A total of P571,725 in operating costs was incurred during that month. Using the high low method, the amount of variable cost per occupied bed per day is?
- b. The mean absolute deviation as of the end of week 10 is___ rentals enter your response here. (Enter your response rounded to two decimal places.)What does the intercept mean in equation below ? X: C18 (total employees hours worked per week) versus Y: C19 (clinic patients seen per week). Equation: y=0.49x+0.84 Slope:0.49 Intercept:0.84 Does the intercept mean it is 0.84 and predicts how many patients seen if zero hours were workeed. In this case it has no meaning , it is only a line fitting?What are the disadvantages and advantages of moving average technique and simple exponential smoothing?
- Mars Incorporated is interested in going to market with a new fuel savings device that attaches to electrically powered industrial vehicles. The device, code named "Python," promises to save up to 15% of the electrical power required to operate the average electric forklift. Mars expects that modest demand expected during the introductory year will be followed by a steady increase in demand in subsequent years. The extent of this increase in demand will be based on customer's expectations regarding the future cost of electricity, which is shown in Table 1. Mars expects to sell the device for $300 each, and does not expect to be able to raise its price over the foreseeable future. Mars is faced with two alternatives: ≻Alternative 1: Make the device themselves, which requires an initial outlay of $450,000 in plant and equipment and a variable cost of $175 per unit. ≻Alternative 2: Outsource the production, which requires no initial investment, but incurs a per unit cost…Weighted Moving Average method is equivalent to moving average method, if the weights are considered equal: True or False?a) Calculate the three point moving averages (quarters) and seasonal variation for the above data b) A detective figures he has a one in nine chance of recovering stolen property. His out-of-pocket expenses for the investigation are $9,000. He is only paid his fee if he recovers the stolen property, what should he charge clients in order to breakeven? c) At races, your horse, has a probability of 1/20 of coming 1st, 1/10 of coming 2nd and a probability of 1⁄4 in coming 3rd. First place pays $4,500 to the winner, second place $3,500 and third place $1,500.Hence, is it worth entering the race if it costs $799? d) Your company plans to invest in a particular project. There is a 35% chance you will lose $30,000, a 40% chance you will break even, and a 25% chance you will make $65,000. Based solely on this information, what should youdo? e) A manufacturer is considering the production of a new and better mousetrap. She estimates the probability that the new mousetrap is successful is 3⁄4.…
