Predictive Analytics to Improve Inventory Performance: A Case Study of an FMCG Company

Abstract

Predictive analytics is a methodology used to predict the outcome of future events with the use of historical data. Predictive analytics comes in very handy in various fields such as finance, manufacturing, healthcare, and even supply chain. Not only in those fields, but predictive analytics is also useful in managing inventory. However, we find that there is a lack of studies focusing on the implementation of predictive analytics to predict inventory status (overstock, understock) by considering inventory level and demand forecast. This study is inspired by a real-world problem at one of the largest FMCG companies in Indonesia. With so many product types to manage, this company often faces problems of understocked and overstocked inventory. This study attempts to solve that problem by employing big data and predictive analytics approaches. The gradient boosting model is used because it is an improvement of the decision tree model. The data that are used as predictors are inventory level, inventory week cover, historical sales, and demand forecast. The target variable for classification is inventory status which is divided into three classes, namely understock, normal, and overstock. Meanwhile, the target variable for the regression model is the amount of understock/overstock. The result of the classification model has an accuracy of 0.84 for category 1 products, 0.76 for category 2 products, and 0.74 for category 3 products. While the result of the regression model is an R 2 of 0.89 for category 1 products, 0.76 for category 2 products, and 0.74 for category 3 products. The data that comes from the prediction model are visualized in a dashboard. The visualization dashboard displays the data using heatmaps and line graphs, so the information can be used for further analysis.

The Role of Predictive Analytics in Optimizing Supply Chain Resilience: A Review of Techniques and Case Studies

“…This case study underscores the importance of predictive analytics in mitigating supply chain risks and ensuring the timely delivery of components, which is crucial in complex manufacturing environments. Suwignjo et al (2023) explore the application of predictive analytics in improving inventory performance for one of the largest Fast-Moving Consumer Goods (FMCG) companies in Indonesia. Faced with challenges of understocked and overstocked inventory across numerous product types, the company employed predictive analytics to optimize inventory levels.…”
