Using the figures in Table 1, forecast the number of surgeries in year 9 using a 3-year moving average and exponential smoothing using an alpha of 0.20and assuming that the forecast for period 8 is 750
Q3 (a) Forecast the demand for month of October using the methods described by i-iv. Demand data for an interior decoration contractor is recorded in Table 3. (i) Naive. (ii) 3-period simple moving average. (iii) 4-period weighted moving average with weightage value of 0.4, 0.3 and 0.2 (highest value for the most recent period). It is a common understanding that the summation of weight factors shall equal to 1. (iv) Exponential smoothing with a = 0.3.
