Estratégias sustentáveis nas operações de produção por encomenda: uma abordagem por processos

Abstract

The growing demand for sustainable industrial operations encourages the adoption of strategies that minimize environmental impacts and promote efficiency in the use of resources. For production-to-order organizations, which are characterized by the customization and adaptation of products to specific customer needs, the challenge is to implement sustainable strategies, given the variability and complexity of the processes involved. This gap hinders effective decision-making and the implementation of models to balance industrial operations. The existing literature deals extensively with sustainable practices in mass production contexts, but lacks in-depth studies and models for made-to-order production operations, capable of dealing with the variability of demand and the complexity of customized processes. To address this issue, the study developed a sustainable operations model for made-to-order production. The model was built using a Systematic Literature Review (SLR) of the Scopus database, with a search string that resulted in a bibliographic portfolio of 55 scientific articles. Twenty-six key criteria were identified from the literature, linked to sustainability in industrial operations. These 26 criteria were validated by industry experts and reduced to 9 criteria. They were divided equally into environmental, social and governance pillars. They were structured into a multi-criteria method to support decision-making on improvements to the production process, using the Value Stream Mapping (VSM) tool and the multi-criteria Best Worst Method (BWM). The model developed was divided into six stages to identify areas for improvement in the organization, the first stage was to define the Kaizen team, the second stage was to determine the product family, the third stage was to design the current VSM, the fourth stage was to carry out the future VSM, the fifth stage was to prioritize actions using the BWM and the last stage was to establish the standardization of the work. In order to carry out the study, two case studies were carried out in an industry that manufactures generators for hydroelectric power plants located in the interior of Paraná. It can therefore be said that the proposed model contributes to the industry's decision-making process under the pillars of invironmental, Social and Governance (ESG), prioritizing actions aimed at reducing waste, optimizing the production process, balancing and standardizing operations.
