Metropolitan Hospital has estimated its average monthly bed needs as N=1,000+9X where X=timeperiod(months);January2002=0 N=monthlybedneeds Assume that no new hospital additions are expected in the area in the foreseeable future. The following monthly seasonal adjustment factors have been estimated, using data from the past five years: Forecast Metropolitans bed demand for January, April, July, November, and December 2007. If the following actual and forecast values for June bed demands have been recorded, what seasonal adjustment factor would you recommend be used in making future June forecasts?
In the Southern Company Managerial Challenge, which alternative for complying with the Clean Air Act creates the greatest real option value? How exactly does that alternative save money? Why? Explain why installing a scrubber burns this option.
Assume the relationship between the growth of a fish population and the population size can be represented as g= 8S – 0.2S2, where g is the growth in tons and S is the size of the population (in thousands of tons) a. Given a price of $100 a ton of fish, what is the marginal benefit of smaller population sizes? b. Estimate the population size that is compatible with the maximum sustainable yield. What would be the size of the annual catch if the population were to be sustained at this level? c. If the marginal cost of additional catches (represented in terms of the population size) is MC= 3(120-S), what is the population size that is compatible with the efficient sustainable yield? d. Is there a difference between the maximum sustainable yield you calculated in part (b) and the efficient sustainable yield in part (c)? Why or why not? Explain briefly (in 1 paragraph or less)
A major South African city generates electricity and sells it to its consumers. The city faces competition from independentrenewable power producers who also have licences to sell electricity to the public. The city however has cost advantagesdue to its size, but it is concerned of the political and economic ramifications of raising its tariffs, in these uncertaineconomic times. As a result, it is highly likely that tariffs will remain unchanged over the next financial year. The city’smarginal revenue is given as R3 000, and its costs are given as follows:TC = R82 000 + R1 000 + 0.01q2 MCMC= R1 000 + R0.02q4.1 Assess the efficiency arguments in favour of and against the renewable energy generation in SouthAfrica
Q5) A firm is planning to manufacture a new product. The sales department estimates that the quantity that can be sold depends on the selling price. As the selling price is increased, the quantity that can be sold decreases. Numerically they estimate: P = $35.00 - 0.02Q where P =selling price per unit Q = quantity sold per year On the other hand, the management estimates that the average cost of manufacturing and selling the product will decrease as the quantity sold increases. They estimate C = $4.00Q + $8000 where C = cost to produce and sell Q per year The firm's management wishes to produce and sell the product at the rate that will maximize profit, that is, where income minus cost will be a maximum. What quantity should the decision makers plan to produce and sell each year?
Problem 2: Assume that a company has the following data for one of its manufacturing cells:Theoretical velocity: 40 units per hourProductive minutes available (per year): 1,200,000Annual conversion costs: $4,800,000Actual velocity: 30 units per hourRequired:1. Calculate the actual conversion cost per unit using actual cycle time and the standardcost per minute.2. Calculate the ideal conversion cost per unit using theoretical cycle time and the standardcost per minute. What incentive exists for managers when cycle time costing is used?3. What if the actual velocity is 36 units per hour? What is the conversion cost perunit? What effect will this improvement have on delivery performance? Cheat Notes :Cycle time (time/units produced)velocity (units produced/time)
A CI is desired for the true average stray-load loss μ (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. Assume that strayload loss is normally distributed with σ = 3.0.a. Compute a 95% CI for μ when n = 25 and = 58.3.b. Compute a 95% CI for μ when n = 100 and = 58.3.c. Compute a 99% CI for μ when n = 100 and = 58.3.d. Compute an 82% CI for μ when n = 100 and = 58.3.e. How large must n be if the width of the 99% interval for μ is to be 1.0?

Prominent Sdn Bhd produces furniture at several factories. Its Seberang Prai factoryproduces office chairs. Management aims to increase production in the coming year to 800units per month. Therefore, management is exploring two production strategies for thecoming year. The first strategy is to continue operations with the existing machine, MachineA, and the second strategy is to rent a new machine, Machine B, to produce the office chairs.The monthly rental of Machine B is RM14,000. Machine B takes half an hour to produce oneoffice chair. However, it requires a more skilled labour force with an hourly rate of RM30 perhour.Comparatively, continuing to use Machine A means that costs will remain the same. MachineA is 5 years old and is operating below capacity. The hourly labour rate is RM20 and thematerials required for each unit is RM30. Each office chair is assembled within an hour. Eachunit of the finished office chair is sold for RM120.The fixed monthly running costs of thefactory is…
