A company wants to forecast demand using the simple moving average.
If the company uses four prior yearly sales values (year 2014 = 100, year
2015 = 120, year 2016 = 140, and year 2017 = 210), which of the
following is the simple moving average forecast for year 2018?
a) 100.5
b) 140.0
c) 142.5
d)145.5
e) 155.0 Ans🗸🗸🗸 c) 142.5
forecast for 2018 = (100+120+140+210)/(4) = 570/4 = 142.5

A company wants to forecast demand using weighted moving average. If
the company uses three prior yearly sales values (2015 = 160, 2016 =
140, and 2017 = 170), and we want to weigh year 2015 at 30%, year
2016 at 30% and year 2017 at 40%, which of the following is the
weighted moving average forecast for year 2018?
a) 170
b) 168
c) 158
d) 152
,e) 156 Ans🗸🗸🗸 c) 158
forecast for 2018 = (160x0.3)+(140x0.3)+(170x0.4) = 158

Collaborative Planning, Forecasting, and Replenishment (CPFR) is a
web-based tool used to coordinate demand forecasting, production nd
purchase planning, and inventory replenishment between supply chain
trading partners. in practice CPFR often doesn't deliver on its' promise
because...
1) computer systems at supplier companies cannot be made to work with
each other
2) forecast errors accumulate as data exchanges are made down the
supply chain cumulating in the 'feast or famine' phenomena known as
the 'bullwhip effect'
3) firms in supply chain may not trust each other sufficiently to share
information openly
4) conflicting objectives between the profit-maximizing vendor and the
cost-minimizing customer give rise to adversarial supply chain
