The flower industry is one of the strongest worldwide. In Latin America, sales represent approximately 30% of the world total, which makes it the second largest flower exporting region. The case study company seeks to implement strategies to improve business competitiveness through the proper management of work areas, since it has been identified that the distribution of facilities is inappropriate and does not allow continuous work between processes. This generates various ergonomic risks such as repetitive movements and forced working postures, which generate bottlenecks and delays in the production chain. The main purpose of this study was to propose a redistribution of facilities with ergonomic studies of the workstations in the post-harvest area of a flower company. The research was field research, information was collected through observation and bibliographic-documentary type, which consisted in the search for information in sources of scientific relevance. In turn, a proposal for the redistribution of facilities was developed, including the design of workstations and analysis of movements and postures. This proposal was analyzed using FlexSim software. The results of the model, with an accuracy level of 95.5%, allow increasing the capacity from 836 to 900 boxes processed per month and decreasing the travel distance from 39.61 to 33.95 m.
