One of the major assumptions considered in various inventory control models is that the issuance of goods and their delivery to the customer is considered a continuous process, while in reality, vehicles are used for delivering goods, and a continuous replenishment policy is usually infeasible. In this regard, numerous researchers have conducted extensive studies since the 1990s and have addressed various aspects of this type of delivery policy, using keywords such as periodic delivery, discrete delivery, multiple shipments, etc. In this research, a literature review of multiple shipment models in inventory control systems is provided, and in this regard, approximately 120 scientific articles that included this topic in their titles, keywords, diagrams, and detailed discussions in the text have been reviewed. Out of all these articles, 68 articles have been further examined, some of which will be visible in a comparative table format. Additionally, the reviewed articles are categorized into two types: based on the type of model and based on the details of multiple shipments, and they are discussed under these titles.
