Combinando modelagem de equações estruturais de mínimos quadrados parciais (PLS-SEM) e Modelo de Decisão Multicritério PROMETHEE ROC para ranquear os fatores relacionados ao Sistema de Gestão Integrada

Abstract

Integrated Management Systems (IMS) are a set of processes, policies, procedures, and organizational practices combined into a single unified framework to manage an organization's operations. IMS is formed by the integration of quality, environmental, and occupational health and safety management systems, aiming for a unified approach to effectively administer these areas. This integration allows for benefits related to operational efficiency, cost reduction, increased customer satisfaction, regulatory compliance, the promotion of an organizational culture focused on quality and sustainability, risk reduction, accident prevention, and minimizing the environmental impact of the company's operations. The objective of this work is to analyze the degree of perception that workers have of an integrated management system composed of the Quality Management System (QMS), Environmental Management System (EMS), and Occupational Health and Safety Management System (OHSMS) in an electric sector company, in order to understand how the IMS factors are perceived by workers, and to rank these factors through a multi-criteria method that can assist in decision-making. The analysis employs a hybrid approach using Partial Least Squares Structural Equation Modeling (PLS-SEM) and the multi-criteria method Preference Ranking Organization Method for

Enrichment Evaluation II (PROMETHEE II) with the Rank Order Centroid (PROMETHEE- ROC) weight elicitation procedure. PLS-SEM was used to measure the factors that form

workers' perceptions and to validate the reliability and robustness of the proposed overall model, while PROMETHEE-ROC was used to rank the IMS items. The results confirm the presence of three management constructs (EMS, QMS, and OHSMS) present in IMS. The model proved to be robust and reliable in measuring workers' perceptions of IMS. Finally, the ranking showed that the items requiring the most effort from the company are those addressed by questions 25 (related to OHSMS), and 14, 16, and 19 (related to EMS). These questions respectively deal with workers' dissatisfaction with working hours, the organization's concern with reducing the amount of solid waste generated, structured organizational policies on environmental education, a culture of sustainable development, and the lack of perception regarding a healthy and safe work environment. Knowledge of these critical points is of great value for decision-making within the organization and guides future measures to improve IMS and base organizational decisions.
