Abstract

For any retail company, managing inventory is of prime importance. Every store should have enough items so that it can fulfill the demand. To achieve this, the stores must be restocked before those items become out of stock. For restocking, the items must arrive from a fulfillment center which distributes the items to various stores, also called distribution centers. Since, distribution center and fulfillment centers are generally far from each other, there is a delay between request for restock and the time it takes for the item to reach from fulfillment centers to distribution centers. To prevent out of stock conditions, the request should be made by considering the time it takes for an item to arrive from fulfillment center. The quantity of item also determines the request time as only few quantities of large items can be sent at once and need multiple transits to restock to the required numbers. Along with these, there are other conditions like general traffic, seasonal climate variations, etc. that can affect the transit time of items. All of these conditions must be taken care while deciding when the item is requested. The proposed system decides the request time and quantity of items along with different variations by training from years of data. This allows the system to work more efficiently and prevent the out of stock conditions to increase sales of the company.
