The 17 Sustainable Development Goals and their 169 associated targets address five areas of critical importance: people, planet, prosperity, peace, and partnership. The purpose of this paper is to take the metrics and data provided and transform them into a fuzzy logic setting. This allows for the analysis of the results in SDG Index and Dashboards Report 2019 by using the techniques of fuzzy logic. Many of these 17 Sustainable Development Goals are related to the terrible crime of human trafficking. We also examine these goals in a fuzzy logic setting.<\/jats:p>","DOI":"10.3390\/sym12010087","type":"journal-article","created":{"date-parts":[[2020,1,3]],"date-time":"2020-01-03T11:55:07Z","timestamp":1578052507000},"page":"87","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Fuzzy Logic Applied to Sustainable Development Goals and Human Trafficking"],"prefix":"10.3390","volume":"12","author":[{"given":"John N","family":"Mordeson","sequence":"first","affiliation":[{"name":"Department of Mathematics, Creighton University, Omaha, NE 68178, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8478-9245","authenticated-orcid":false,"given":"Sunil","family":"Mathew","sequence":"additional","affiliation":[{"name":"Department of Mathematics, National Institute of Technology, Calicut 673601, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,2]]},"reference":[{"key":"ref_1","unstructured":"Burck, J., Hagen, U., Marten, F., Hoehne, N., and Singer, S.
