I am working on determining optimal order quantity for the Sport Obermeyer case. " Using the data in Exhibit 10, make a recommendation for how many units of each style Wally should make during the initial phase of production. Assume that all ten styles in the sample problem are made in Hong Kong and that Wally's initial production commitment must be at least 10,000 units. Ignore price differences among styles in your initial analysis."
The exhibit provides cost for each style, 6 sales forecasts and an average forecast. Standard deviation and 2x standard deviation are also given.
