Optimizing your warehouse means examining every corner of your infrastructure and every facet of your workflows and processes to identify and correct inefficiencies. Not only does warehouse optimization result in a healthier bottom line, but it also improves key warehouse metrics like accurate orders and on-time delivery.

Our solution for this optimization problem attempts to use Machine Learning techniques to provide a scalable and fast solution to this problem. We used several models like Decision tree, Random Forest Classifier, XGBoost classifier, k-Nearest Neighbours, etc to solve this issue.

The highest accuracy we obtained so far is 89% in Random Forest Classifier. The following graph shows our confusion matrix plot for RFC at various values of n_estimators

As you can see in the graph, the classification of item into -1th bin is where our error lies. When the bins are full and the algorithm is supposed to not place the item, our algorithm is placing it into a bin. That is where the algorithm is malperforming,
