4R (4R Systems, Inc.) is a Berwyn, Pennsylvania software company founded in 1999 that sells a cloud-based intelligent inventory optimization platform and planning service to retail chains. Its prescriptive-analytics products cover demand planning, replenishment planning, allocation planning, assortment optimization, markdown optimization and vendor order optimization, combining statistical and machine-learning forecasting with a managed "planning as a service" team. Customers reach the platform through a hosted web portal and scheduled data exchanges rather than a public developer API; 4R publishes no developer portal, documentation or machine-readable API contract on its public site.
