Multicriteria methods have gained traction in academia and industry practices for effective decision-making. This systematic review investigates and presents an overview of multi-criteria approaches research conducted over forty-four years. The Web of Science (WoS) and Scopus databases were searched for papers on multi-criteria methods with titles, abstracts, keywords, and articles from January 1977 to 29 April 2022. Using the R Bibliometrix tool, the bibliographic data was evaluated. According to this bibliometric analysis, in 131 countries over the past forty-four years, 33,201 authors have written 23,494 documents on multi-criteria methods. This area’s scientific output increases by 14.18 percent every year. China has the highest percentage of publications at 18.50 percent, followed by India at 10.62 percent and Iran at 7.75 percent. Islamic Azad University has the most publications with 504, followed by Vilnius Gediminas Technical University with 456 and the National Institute of Technology with 336. Expert Systems with Applications, Sustainability, and the Journal of Cleaner Production are the top journals, accounting for over 4.67 percent of all indexed works. In addition, E. Zavadskas and J. Wang have the most papers in the multi-criteria approaches sector. AHP, followed by TOPSIS, VIKOR, PROMETHEE, and ANP, is the most popular multi-criteria decision-making method among the ten nations with the most publications in this field. The bibliometric literature review method enables researchers to investigate the multi-criteria research area in greater depth than the conventional literature review method. It allows a vast dataset of bibliographic records to be statistically and systematically evaluated, producing insightful insights. This bibliometric study is helpful because it provides an overview of the issue of multi-criteria techniques from the past forty-four years, allowing other academics to use this research as a starting point for their studies.

Purpose: In a view to its comprehensive and diverse applicability, the methodology Lean Six Sigma (LSS) has the potential to the generation of impacts on various aspects of an organization. This paper aims to carry out a systematic study of LSS impacts on organizations, analyzing their relation to organizational sustainability through the triple bottom line perspective.Design/methodology/approach: A systematic review of the existent literature on LSS was performed and the identified impacts were later classified as correspondence with three dimensions of organizational sustainability: financial, social and environmental.Findings: There were identified 25 main impacts of the LSS through a systematic research of the literature. A greater correspondence of the LSS have been identified over a range of economic results in organizations; however, it was also possible to notice that the methodology has been directing its efforts gradually to meet further perspectives of sustainability, particularly by looking for a better relation with employees and customers.Practical implications: The organizations that use the LSS as methodology to continuous improvement will be able to identify which impacts may need to be achieved primarily by the projects undertaken to enhance the achievement of a more sustainable management. Because of its comprehensive character, this paper can help organizations belonging to various industries and sectors of society.Originality/value: Despite the growing number of published articles on the methodology LSS, it has not been identified articles that look for the study of the application of the methodology as a mechanism for increasing sustainability in organizations. Within the scenario presented, this study sought to assist the filling of this gap.
