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.
