A systematic literature review of imperfect quality items: challenges, opportunities, and insights with reference to SDGs

Every business sector has inventory problems whether they are realized or not. The occurrence of imperfect quality items (IQI) in the inventory is obvious and cannot be overlooked. As mismanagement of these items may end up in waste emancipation and harmful environmental impacts. Copious work has been done in the area of inventory modeling for IQI with varying demand patterns which calls for a systematic review framework so as to assist the researchers and professionals with the direction of flow of the current and existing research. The present Systematic Literature Review (SLR) studies the inventory models with varying demand patterns under the presence of IQI. This study considered 107 peer-reviewed articles for the SLR obtained after a detailed study of 782 articles through the Web of Science database. VOSviewer has been used for the network analysis and visualization. The software provide the insights to identify and analyze the linkage between the considered problem for the bibliometric analysis and the relationship between the authors, keywords, countries etc. The insights are presented as to how the management of IQI can be a benchmark for an organization and contribute to several Sustainable Development Goals (SDGs). The time span for this study is from 2010 to 2024^* (up to 29 February).
