Six Sigma (6\u03c3) is a set of techniques and tools for process improvement. The tools of Six Sigma apply within a simple improvement model known as Define\u2013Measure\u2013Analyze\u2013Improve\u2013Control (DMAIC). This paper shows that implementing Six Sigma can be more effective in managing the vehicle fleet. The combination of mathematical, i.e., statistical basis and practice makes Six Sigma so successful. The Six Sigma project, implemented to reduce costs and increase the availability of a vehicle fleet in a selected company, can be widely applied in other similar enterprises.<\/jats:p>","DOI":"10.3390\/sym12050857","type":"journal-article","created":{"date-parts":[[2020,5,25]],"date-time":"2020-05-25T11:42:02Z","timestamp":1590406922000},"page":"857","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Application of Six Sigma Model on Efficient Use of Vehicle Fleet"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7407-8239","authenticated-orcid":false,"given":"Tatjana","family":"Stanivuk","sequence":"first","affiliation":[{"name":"University of Split, Faculty of Maritime Studies, 21000 Split, Croatia"}]},{"given":"Tamara","family":"Gvozdenovi\u0107","sequence":"additional","affiliation":[{"name":"Hydro Power Plants on the river Trebisnjica; 89104 Trebinje, Bosnia &amp; Herzegovina"}]},{"given":"Jelena","family":"\u017dani\u0107 Mikuli\u010di\u0107","sequence":"additional","affiliation":[{"name":"University of Split, Faculty of Maritime Studies, 21000 Split, Croatia"}]},{"given":"Vesko","family":"Lukovac","sequence":"additional","affiliation":[{"name":"Traffic Engineering-Transportation and Labour Organization, University of Defence; Military Academy-Chair of Logistics, 11000 Belgrade, Serbia"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,22]]},"reference":[{"key":"ref_1","unstructured":"Desai, T.N., and Shrivastava, R.L.
