Abstract

Abstract: Equipment replacement is a definitive and relevant engineering decision. The aim of this work was to identify and organize the mathematical optimization proposals and solution search techniques that have contributed toward solving this problem. As a result, we classified the bibliographic materials we identified into seven distinct types of approaches. The work also provides an integrative overview of the level of complementarity of the categories we identified. The network visualization approach represented about 57% of the selected works and is still in use today. Nonetheless, since 2000 other approaches, such as fuzzy logic, real options, and machine learning have increased by 40% and become relevant current trends.

Keywords

Equipment replacement policy, Mathematical programming, Optimization

Resumo

Resumo: A substituição de equipamentos é uma relevante decisão de engenharia. O objetivo deste trabalho foi identificar e organizar as propostas de otimização matemática e as técnicas de busca de resultados que têm contribuído para a solução deste problema. Como resultado, classificamos os materiais bibliográficos identificados em sete tipos distintos de abordagens. O trabalho também fornece uma visão integradora do nível de complementaridade das categorias identificadas. A abordagem de visualização em rede representou cerca de 57% dos trabalhos selecionados e ainda está em uso. No entanto, desde 2000 outras abordagens, como lógica fuzzy, opções reais e aprendizado de máquina aumentaram 40% e se tornaram tendências atuais relevantes.
