The Winters’ model

The forecast method chosen for this analysis is the Winter’s Model or the “multiplicative decomposition (seasonal) method” (Forecasting in Supply Chains, 2012). This model takes into account the lever, trend, and seasonality factors with the historical customer demand data to determine future operations and production schedules to meet future demand. The Winter’s Model uses the “seasonal factors and assigns different weights to adjust the trend components” (Anderson & Semmelroth, 2016). The wine industry is cyclical in nature (Cuellar & Lucey, 2005) so the Chardonnay supply chain will need to have forecasting method that is adaptive. With the use of the Winter’s Model, the supply chain will be able to adapt the “forecasting process to adjust to the change in the demand observation” (Chopra & Meindl, 2016, p. 187). …show more content…
The wine industry is seasonal (THST 10-K, 2016), with the busiest sales months predicted to be in the fall. To ensure the Chardonnay wine supply chain properly plans to avoid stock outs on the product certain operational factors will need to be determined. Table 1 lists three factors along with the impact on the aggregation planning in the wine supply
