There is a special system mechanism for perishable goods, called FRESH. This algorithm is based on mathematical statistics principles and takes into account the standard variation (from the average sales level), customer service performance (in other words, the likelihood the consumer finds the needed product on the shelves), weekday coefficient (demand can vary depending on the weekday; this coefficient is being calculated automatically), as well as product expiration date.

The goods which are being managed using FRESH algorithm, need accurate data on average daily sales and current level of write-offs (by the customer). The day the order is made, the system calculates the necessary quantity needed to satisfy demand in the period between the deliveries, taking into account the residual expiration term and the demand variability (which may change according to the day of the week).
