If D = 7,800 per month, S = $46 per order, and H = $2.00 per unit per month, a) What is the economic order quantity? The EOQ is units (round your response to the nearest whole number). Week Of August 31 September 7 September 14 September 21 September 28 October 5 Pints Used 360 370 408 378 368 371 a) The forecasted demand for the week of October 12 using a 3-week moving average = 372.33 pints (round your response to two decimal places). b) Using a 3-week weighted moving average, with weights of 0.10, 0.35, and 0.55, using 0.55 for the most recent week, the forecasted demand for the week of October 12 = 370.65 pints (round your response to two decimal places and remember to use the weights in appropriate order the largest weight applies to most recent period and smallest weight applies to oldest period.) c) If the forecasted demand for the week of August 31 is 360 and a = 0.20, using exponential smoothing, develop the forecast for each of the weeks with the known demand and the forecast for the week of October 12 (round your responses to two decimal places). Week Of Pints Used Forecast for this Date 360 August 31 September 7 September 14 September 21 360 370 408 360.00 362.00 378 Following are two weekly forecasts made by two different methods for the number of gallons of gasoline, in thousands, demanded at a local gasoline station. Also shown are actual demand levels, in thousands of gallons: Forecast Method 1 Actual Demand Forecast Method 2 Week Week 0.95 1.08 0.97 1.20 AWN- 0.68 1.00 1.07 1.00 Actual Demand 0.68 1.00 1.07 1.00 0.77 1.21 0.90 1.17 AWN The MAD for Method 1 = thousand gallons (round your response to three decimal places). William Beville's computer training school, in Richmond, stocks workbooks with the following characteristics: Demand D Ordering costs Holding cost H 19,500 units/year $25/order $4/unit/year a) The EOQ for the workbooks is 494 (round your response to the nearest whole number). b) What are the annual holding costs for the workbooks? $ (round your response to the nearest whole number). Week Actual No. of Patients 65 69 oo AWN- 76 59 64 73 Clinic administrator Dana Schniederjans wants you to forecast patient numbers at the clinic for week 7 by using this data. You decide to use a weighted moving average method to find this forecast. Your method uses four actual demand levels, with weights of 0.500 on the present period, 0.250 one period ago, 0.125 two periods ago, and 0.125 three periods ago. a) What is the value of your forecast? The value of the forecast is 69.38 patients (round your response to two decimal places). b) If instead the weights were 40, 20, 10, and 10, respectively, how would the forecast change? O A. The value of the forecast will increase. O B. The value of the forecast will decrease. C. The value of the forecast will remain the same. c) What if the weights were 0.60, 0.20, 0.10, and 0.10, respectively? Now what is the forecast for week 7? The value of the forecast is patients (round your response to two decimal places)
