This study focuses on the application of the concepts of Lean production in the process of replenishing products on the shelves of the shops of one of the largest food retail chains in Portugal. Methods: This study aims to apply a transition from a \u201cpush\u201d to a \u201cpull\u201d approach, based on real-time consumption. During a 5-day test, the impacts of implementing Lean principles and ergonomic trolleys in the process were investigated. Results: The test led to improved efficiency in product replenishment by eliminating pallets and reducing unfavourable product handling from the initial process. The implementation of a replenishment system in this manner allowed a reduced labour requirements from 28.4 to 19.2 man-hours per day and, the elimination of unnecessary handling and increase of product availability were reflected in gains on operational time and in replenishment time. Conclusions: This study provides empirical evidence for the effectiveness of Lean pull systems in retail replenishment, demonstrating a 32% reduction in labour hours.<\/jats:p>","DOI":"10.3390\/logistics9020061","type":"journal-article","created":{"date-parts":[[2025,5,16]],"date-time":"2025-05-16T06:57:28Z","timestamp":1747378648000},"page":"61","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Enhancement of In-Store Product Replenishment Flow and Introduction of Pull Approach in a Food Retail Chain"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7354-1017","authenticated-orcid":false,"given":"Elisa","family":"Vieira","sequence":"first","affiliation":[{"name":"Centro Algoritmi, University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3049-7093","authenticated-orcid":false,"given":"Larissa","family":"Tomaz","sequence":"additional","affiliation":[{"name":"Centro Algoritmi, University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"given":"Jos\u00e9","family":"Leit\u00e3o","sequence":"additional","affiliation":[{"name":"Centro Algoritmi, University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-4626-5385","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Centro Algoritmi, University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9724-0312","authenticated-orcid":false,"given":"Jos\u00e9","family":"Dinis-Carvalho","sequence":"additional","affiliation":[{"name":"Centro Algoritmi, University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"87","DOI":"10.1146\/annurev-resource-101619-094219","article-title":"Pricing Strategies of Food Retailers","volume":"12","author":"Hamilton","year":"2020","journal-title":"Annu.
