Abstract
When we conducted our work, we identified that the main problem of the company was the difficulty to forecast accurately its sales for the next season and this uncertainty, even if it can be reduced, will always remain. Thus, our main objective in this case study was to find a way to reduce the inaccuracies in Obermeyer's forecasting process by using the new vendor model and by this mean reduce the cost of forecasting errors for the company. For the production planning and the choice of production locations, we followed the approach of Obermeyer's CEO, of intuitive but logical and limiting the risks for the company. Our calculation allowed us to distinguish two production periods in the company's production planning, the first period before Las Vegas trade show and the second one, introducing the trade show's feedback. Regarding the fact that we considered that running out of products would be more damageable for the company than having unsold items at the end of the season, we offered in our approach two supplementary months to Obermeyer's former planning period to address any supplement orders or problems.
