PASS
Which of the following forecasting methodologies is considered a time series forecasting
technique? - Answers -Simple moving average
A company wants to forecast demand using the weighted moving average. If the
company uses two prior yearly sales values (i.e., year 2012=110 and year 2013=130),
and we want to weight year 2012 at 10% and year 2013 at 90%, which of the following
is the weighted moving average forecast for year 2014? - Answers -Forecast for 2014 =
(110x0.1) + (130x0.9) = 11 + 117 = 128
Given a prior forecast demand value of 230, a related actual demand value of 250, and
a smoothing constant alpha of 0.1, what is the exponential smoothing forecast value for
the following period? - Answers -Forecast = 230 + 0.1 x (250-230) = 232
A company has actual unit demand for four consecutive years of 100, 105, 135, and
150. The respective forecasts were 120 for all four years. Which of the following is the
resulting MAD value that can be computed from this data? - Answers -MAD =
ABS((100-120)+(105-120)+(135-120)+(150-120))/4 = 80/4 =20
If you were selecting from a variety of forecasting models based on MAD, which of the
following MAD values from the same data would reflect the most accurate model? -
Answers -Since the same data is being used in the question, MAPE would be least
when MAD was smallest.
A company hires you to develop a linear regression forecasting model. Based on the
company's historical sales information, you determine the intercept value of the model
to be 1,200. You also find the slope value is minus 50. If after developing the model you
are given of x=10, which of the following is the resulting forecast value using this
model? - Answers -The linear regression line is of the form Y = a + bX, where Y is the
value of the dependent variable that we are solving for, a is the Y intercept, b is the
slope, and X is the independent variable. Hence, Y = 1,200 + (-50) x 10 = 700.
What is a work breakdown structure? - Answers -A def of the hierarchy of project tasks,
subtasks, and work packages
You have just been assigned to oversee a series of projects. Functional areas will loan
you personnel for each project and separate project managers will be responsible for
separate projects. These project managers will report to you. Which project
management structure is being used? - Answers -Matrix Project
