When producing perishable products or using perishable raw materials, large producers face the problem of organizing supplies and forming stocks, taking into account this specificity of resources. Product shelf life is key in optimizing and synchronizing supply and manufacturing processes. An approach to optimization of delivery not based on VMI-technology of joint inventory management with an extended module for monitoring stocks of perishable goods is proposed. It is noted that monitoring should be carried out according to a specific algorithm based on an economic and mathematical model for managing stocks of perishable goods. The developed model provides the calculation of the optimal proportions for the purchase, storage and sale of perishable products. It is shown that this approach is applicable to the dairy cluster of the Voronezh Oblast, the structure of which includes the logistic subsystem of interaction between the producer and the consumer of the product.
