Determining optimal actions through scenario analysis and optimization techniques.
Forecasting future outcomes using time series analysis and machine learning models.
Accurate Finished Goods (FG) production planning in consumer electronics requires addressing multiple challenges and incorporating diverse data sources:
The first step in our forecasting journey is to understand historical sales patterns, seasonality, and trends in our consumer electronics data to inform production planning.
We begin by loading and examining our historical sales data for patterns, missing values, and outliers that could impact our FG forecasts.

| Shape: | (3,650, 7) |
| Date Range: | 2022-01-01 to 2023-12-31 |
| Categories: | Smartphones, Laptops, Tablets, Speakers, Televisions |
Our analysis revealed the following statistics across product categories:
| Category | Avg Daily Sales | Avg Inventory | Inventory Turnover | Avg Production |
|---|---|---|---|---|
| Smartphones | 281 | 11,350 | 0.62 | 310 |
| Laptops | 186 | 9,138 | 0.49 | 198 |
| Tablets | 216 | 9,634 | 0.54 | 237 |
| Speakers | 202 | 9,521 | 0.51 | 219 |
| Televisions | 166 | 8,701 | 0.46 | 176 |
Inventory turnover ratio indicates how many times inventory is used and replaced during a time period. Higher values suggest better inventory management.
Visualizing historical data helps identify seasonal patterns, long-term trends, and anomalies that affect production planning.
