| Summary: | The main objective of this research is to consider and determine the most optimum
decision on design concept, material and manufacturing process for the automotive
composite bumper beam at the conceptual design stage. The objective was achieved
by proposing two selection frameworks and the use of analytical hierarchy process
under concurrent engineering environment. The research began by generating and
developing eight new conceptual designs of automotive composite bumper beam and
investigating various parameters or criteria and alternatives that normally used to
manufacture automotive composite bumper beam by implementing total design
approach. To determine the most optimum decisions on design concept, material and
manufacturing process for the automotive composite bumper beam, analytical
hierarchy process utilizing Expert Choice software was used. The research revealed
that the glass fibre epoxy with a value of 0.257 (25.7%), design concept-6 with a
value of 0.191 (19.1%) and injection moulding with a value of 0.228 (22.8%) are the
most appropriate decisions on material, design concept and manufacturing process respectively. It was also revealed that importance of addressing various design tools
and considering the most optimum decisions on design concept, material and
manufacturing process at the conceptual design stage in the design flow under
concurrent engineering environment. Overall, it can be concluded that the proposed
selection frameworks, analytical hierarchy process and concurrent engineering
approach allow designers or decision makers to consider and determine the most
optimum decision on design concept, material and manufacturing process at the
conceptual design stage. |
