FUZZY IN LEAN TO EVALUATE THE DECISION DEGREE

Abstract

The research aims to structure hierarchically an approach about the importance in decision making processes in the organizational environment, facilitating the applicability of Lean principles. The proposal was carried out using the Fuzzy - Analytic Hierarchy Process (FAHP). We used the parity and individual matrices between three managers and nine supervisor’s experts in production through individual questionnaire application and focal group. The answers were collected through the categorical application, where the moderator role was conducted by the researchers themselves with six constructs and 33 subconstructs in three companies from different branches, having characteristics closely related in the manufacturing sector. As results about the companies’ operations and processes, the values that obtained the highest degree of importance were the management construct (23%); capacity (22%) and costs (20%). We conclude for Lean principles these three factors have a 65% impact degree on decisions. Keywords: FAHP. Lean. Manufacturing. Decision Making Processes. Production. RESUMO A pesquisa buscou estruturar hierarquicamente uma abordagem sobre a importância em processos decisorios no âmbito organizacional, facilitando a aplicabilidade dos principios Lean. A proposta transcorreu com o auxilio analitico de Fuzzy – Analytic Hierarchy Process (FAHP). Desse modo, utilizou-se das matrizes paritarias e individuais entre tres gestores e nove supervisores especialistas em producao utilizando tecnicas de aplicacao de questionario individual e grupo focal respectivamente. As respostas foram coletadas por meio da aplicacao categorica, no qual o papel de moderador foi realizado pelos pesquisadores, com seis constructos e 33 subconstructos em tres empresas de ramos diferentes, mas com caracteristicas do setor manufatureiras fortemente relacionadas. Como respostas sobre as operacoes e processos das industrias no âmbito atual, os valores que obtiveram maior grau de importância foram o constructo gestao (23%); capacidade (22%) e custos (20%). Conclui-se que, para principios Lean, estes tres fatores engajados impactam em um grau de 65% nas decisoes. Palavras-chave: FAHP. Lean. Manufatureiras. Processos Decisorios. Producao.
