Conceptual design of multi-operation outdoor flexural creep test rig using hybrid concurrent engineering approach

The hybridisation of conceptual design methods is presented in the development of multi-operations creep flexural test rig. The paper explains the integration of theory of inventive problem solving (TRIZ), Morphological chart, and Analytic Network Process (ANP) method to ensure the quality function is fulfilled with the essential requirements. The objective of this project is to produce and choose the best design concept for the product development depending on the product design specifications (PDS). In the early stage of product development, the TRIZ contradiction principles and 40 TRIZ inventive solutions were applied as the guidance tools. To refine the specification of the product design, the principle solution parameters were detailed systematically with the aid of morphological chart. In this article, four innovative conceptual designs of the multi-operations creep flexural test rig were produced and the selection process was conducted using ANP method to perform the multi-criteria decision making process in selecting the best concept design.
