Which of the following forecasting methodologies is considered a time series forecasting
technique? - ✔✔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? - ✔✔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? - ✔✔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? - ✔✔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? - ✔✔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? - ✔✔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? - ✔✔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? - ✔✔Matrix Project
In conducting aggregate operations planning there are a number of required inputs. Which of
the following are inputs considered external to the firm? - ✔✔Raw material availability and
competitor's behavior
In conducting aggregate operations planning there are a number of required inputs. Which of
the following are considered inputs internal to the firm? - ✔✔Current physical capacity and
current workforce
Matching the production rate to the order rate by hiring and laying off employees as the order
rate varies is which of the following pure production planning strategies? - ✔✔Chase
Which of the following costs are relevant to aggregate operations planning? - ✔✔Backordering
costs
Using the cut-and-dry method for aggregate operations planning we can determine the
production requirement in units of product. If the beginning inventory is 100 units, the demand
forecast is 1,200, and the necessary safety stock is 20% of the demand forecast, which of the
following is the production requirement? - ✔✔1,340 (1200;20% of demand=240 and INV.=100)
so, 1200+240-100=1340
From an operational perspective yield management is most effective under which of the
following circumstances? - ✔✔Inventory is perishable
