    1.Forecasts of individual products tend to be more accurate than forecasts of product families.

    個別產品的預測傾向於比系列產品的預測愈來愈精確。

    Ans: 因為雖然是同一系列的產品,但因為群眾的喜好不同,如口味、香味、顏色等的偏好不同,因此個別產品的預估數量就會比整個系列產品的預估數量準確。

    2. The last four weekly values of sales were 80, 100, 105, and 90 units. The last four forecasts were 60, 80, 95, and 75 units. These forecasts illustrate

    前四周的銷售量各為80、100、105及90個單位。而前四周的預估量各為60、80、95及75個單位。這些預估說明

    a.qualitative methods 定性法

    b.adaptive smoothing 自動調整平滑

    c.slope 傾斜度

    d.bias 偏差值

    e.trend projection 趨勢預估
