Speculative Production:
Overstock versus Stockout?
Assume that Sport Obermeyer: is in the Speculative Production phase, forecasts that demand (D) for the Andy parka has a Normal Probability
Distribution with a mean of 1000 and a standard deviation of 250, and has decided that the Andy parka’s Speculative Production should be
Q=750.
Pr{Stockout}=Pr{D>Q}
=0.841
Pr{Overstock}=Pr{D<Q}
=0.159

Speculative Production:
Guidelines for Choosing a Parka to Produce
In this slide and the next 4 slides, we will assume that Sport Obermeyer is in the Speculative
Production phase and must decide whether to produce the Andy parka or the Peter parka.
We will also assume that a parka’s demand has a
Normal Probability Distribution.
We will investigate how this decision is affected by: the parka’s standard deviation of demand, the parka’s mean demand, and the parka’s unit cost of production.

The Effect of a Parka’s
Standard Deviation of Demand
Assume that Andy and Peter have the same unit cost of production and the same mean demand of 1000, but that
Andy’s demand has a standard deviation of 100 while
Peter’s demand has a standard deviation of 200.
