Economic Production Quantity (EPQ) models search two important questions which are how much and when have to produce. The research on EPQ models is still important for many industries under different assumptions on EPQ models. In this paper, the scientific literature of the inventory management and its extensions where is mostly liked for EPQ models are mentioned with historical review by using national and international databases with indexes. The shortages, backordering, imperfect items, quality control and errors, learning curves, financial effects, and uncertainties are mostly seen in this research area for modeling on classical EPQ from the literature since 2000. Thus, we think that the real life problems are well defined by these proposed models. Today, the modelling of the stochastic, fuzzy logic, grey system theory and metaheuristics methods are used for large scale EPQ models. However, in the conclusion of this paper, for industrial practitioners and researchers the new research areas are discussed and presented which are dynamic, vendor- buyer, outsourcing, cancellation of orders, emergency orders, inventory routing, recycling process and close-loop supply chains for EPQ models.
