Application of a fuzzy axiomatic design methodology for ergonomic compatibility evaluation on the selection of plastic molding machines: a case study

This paper presents the application of a Fuzzy Axiomatic Design Methodology for Ergonomic Compatibility Evaluation on the selection of Advanced Manufacturing Technology (AMT). A case study on the selection of CNC plastic molding machines for an AMT training center was developed. The purpose of this methodology is to establish a decision aid for decision makers to perform evaluation of AMT in a more complete manner, while considering human factors and ergonomic aspects. These aspects are found to be scarce in AMT evaluation and selection models. A multi-attribute axiomatic design perspective was used supporting the selection of AMT. An Ergonomic Compatibility Survey was used and the procedure for the data analysis is described. The Ergonomic Compatibility construct was tested and validated using Cronbach Alpha Test observing good reliability of the instrument. A numerical example is presented by the application of the model with the participation of three experts. The alternative which best meet established Design Ranges in terms of Ergonomic Compatibility was selected among three alternatives, according to the Ergonomic Incompatibility Content in a fuzzy environment.
