This article provides an overview of current research in the field of modifying inventory management models, among which the focus is on models for determining the economic order quantity (EOQ) for perishable stock in accordance with various criteria restrictions. The authors implement a meta-analysis of 160 scientific publications, in which modifications of the studied models are foreseen for the period from 2016 to 2021. The result was systematization and classification of each model in accordance with the type of demand, the perishable stock nature, and its deterioration dynamics, as well as the key topic, based on which the limitations of the model are set. The authors formulate conclusions about existing solutions and their applicability in various situations, determine the motives, trends and modifications types of the base model for determining the optimal delivery batch, and determine potential development directions.
