Fuzzy Model to Assess the Level of Lean Manufacturing in a Commercial Air Conditioning Manufacturer
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2023) SOARES, Raquel Borges; NASCIMENTO, Manoel Henrique Reis do
Proper management of factory floor resources is essential for financial health and company competitiveness. Organizations with high levels of waste lose efficiency by focusing on corrections instead of innovation. This study applies Lean Manufacturing methodology to a commercial air conditioning manufacturer, using a fuzzy logic-based model to assess Lean maturity levels. The model incorporates four implemented Lean tools – 5S, VSM (value stream map), TPM (total productive maintenance), and SMED (single minute exchange of die) – to determine Lean Manufacturing levels through computational simulation. The results show that the fuzzy methodology effectively validates Lean maturity and guides improvements in Lean transformation management.
Multicriteria design of passive harmonic filters for industrial installations using evolutionary computation techniques
(INSTITUTO DE TECNOLOGIA, 2015) LEITE, Jandecy Cabral; ABRIL, Ignácio Perez; AZEVEDO, Manoel Socorro Santos; NASCIMENTO, Manoel Henrique Reis do; MORAES, Nadime Mustafa; REIS, Ana Maria; Profa. Dra. Maria Adrina Paixão de Souza da Silva.
This article presents a mathematical method and a computational tool based on Evolutionary Computation (NSGA II) for the multicriteria design of passive harmonic filters in industrial electrical systems. Focused on the Industrial Pole of Manaus (PIM), the study frames the harmonic compensation design as a multi-objective optimization problem, balancing harmonic distortion reduction with economic viability under Brazilian energy tariff structures. The developed tool automatically selects filter configurations and parameters, incorporating standards such as PRODIST-Module 8 and IEEE 519-92. Results demonstrate the effectiveness of the approach.
