Understanding the Machine Learning (AI) in StockTrim's Inventory Forecasting

May 12,2024

Inventory management plays a vital role in the success of businesses, and accurate forecasting is key to optimizing inventory levels. StockTrim, a leading inventory forecasting solution, leverages advanced techniques, such as time series regressions, within its machine learning inventory forecasting. But what exactly does that mean? Let's dive in and explore the fascinating world of time series regressions and how StockTrim utilizes them to enhance inventory planning.

Explaining Time Series Regressions:

Time series regressions are statistical models used to analyze and predict the relationship between variables over time. In the case of StockTrim's inventory forecasting, time series regressions enable them to understand how different factors impact inventory levels and make reliable predictions.


The Process:

1. Data Collection: StockTrim gathers historical inventory data, including relevant variables such as sales, demand, lead times, pricing, promotions, and more. 

2. Data Preprocessing: To ensure accurate analysis, StockTrim cleans and preprocesses the data, handling any missing values or outliers. They also account for seasonality, trends, and other factors that may influence inventory levels.

3. Model Selection: StockTrim carefully selects an appropriate time series regression model, such as ARIMA, SARIMA, or exponential smoothing. These models effectively capture the inventory dynamics and incorporate relevant independent variables.

4. Model Estimation: Through optimization techniques like maximum likelihood estimation, StockTrim fits the selected model to the training data. This estimation process helps determine the parameters of the regression equation, considering the historical inventory data and other relevant variables.

5. Model Evaluation: StockTrim assesses the model's performance by analyzing the residuals and evaluating metrics like MSE (mean squared error) and RMSE (root mean squared error). This step ensures the accuracy and reliability of the inventory forecasts.

6. Inventory Forecasting: With a validated model, StockTrim leverages it to forecast future inventory levels based on the values of relevant independent variables. These forecasts assist in optimizing reorder points, identifying potential stockouts or overstocking situations, and improving procurement or production planning. 


StockTrim's inventory forecasting using time series regressions allows businesses to optimize their inventory management and streamline supply chain operations. By analyzing historical data and incorporating relevant variables, StockTrim can accurately predict future inventory levels. It is worth not that this is just one of StockTrims methods -there are other things that impact good forecasting and demand planning that are built into the App (eg: buffer stock, and other configurable parameters).

This technology is a testament to the ongoing advancements in inventory management, benefiting businesses across various industries. Now even SMB’s (small & medium sized businesses) can have access at very affordable monthly subscriptions. This has been previously unobtainable except to only the largest of enterprises.

By understanding the significance of time series regressions and how they contribute to StockTrim's inventory forecasting, businesses can appreciate the power of data-driven decision-making in inventory optimization.
