/pain-points

The retail industry faces a dilemma โ€” empty shelves versus warehouse overflow.

๐Ÿ“ฆ Empty Shelves
Lost sales opportunities and disappointed customers. When demand spikes, traditional systems can't keep up.
๐Ÿญ Warehouse Overflow
Excess inventory ties up capital and leads to expired products. Over-ordering is as costly as under-ordering.
โš ๏ธ Global retailers lose $1.1 trillion annually due to forecasting errors (Statista 2023)

/why-rules->neural-nets

IF Temperature = Very Hot
AND Historical_Sales = High
THEN Tomorrow_Replenishment = +50%
// Transparent. Explainable. Adjustable by humans.

Rules provide transparent, explainable logic that can be easily understood and adjusted by humans โ€” unlike the "black box" of neural networks.
