- Clustering analysis – A case studyPublication . Sena, Inês; Mendes, João; Fernandes, Florbela P.; Pacheco, Maria F.; Vaz, Clara B.; Pires, Abel A.C.; Maia, Jaime P.; Pereira, Ana I.In retail sector there is a high number of work accidents causing economic losses, musculoskeletal injuries, among other prob-lems. To avoid future injuries and accidents, it is essential to develop intelligent systems to minimize the risk of accidents, providing a zero accidents culture in these sectors. This work concentrates efforts to highlight the importance of employees’ personal and professional characteristics in preventing accidents, as well as the need to study several stores with different characteristics. Thus, a questionnaire was developed and implemented in two different stores to collect responses. The collected data will be analyzed using the k-means algorithm using Matlab software.
- Occupational behaviour study in the retail sectorPublication . Sena, Inês; Fernandes, Florbela P.; Pacheco, Maria F.; Pires, Abel A.C.; Maia, Jaime P.; Pereira, Ana I.The health, safety, and well-being of employees, service providers, and customers are important priorities for retail companies. Based on this principle, an intelligent system that contributes to the reduction of accidents at work will be developed, monitoring risk control, preventing work-related illnesses, promoting a culture of zero accidents, and seeking to ensure the health of employees, customers, and stakeholders. In order to achieve such goals, it is necessary to determine the local and global variables (internal and external) that feed the system. This study comprises the first strategy applied to collect the local variables involved in the problem. To obtain this, a data analysis study in a retail store was performed. Data analysis procedures were performed namely clustering analysis with algorithm k-means, correlation procedures, like Pearson coefficient and matrix of correlation, and relationship analysis with parallel coordinate graphs. From the preliminary results, it is possible to indicate a set of local variables that have influence in the occupational behavior and accidents at work.
