A major challenge of tomorrow's innovative retail is to guarantee a flawless customer experience in order to build customer loyalty and increase customer value over time. The availability of fast-moving items on the shelf is the primary motivation for buying in the shop. The scarce character of promotions and the unstable economic environment make it particularly time-consuming for the retailer to precisely anticipate promotional demand. Can AI contribute to reduce on-shelf shortages and improve the in-store client experience? Decision intelligence is a new type of solution that brings AI algorithms to specific decision-making processes, for instance to optimize supply flows for promotional sales.
