DEVELOPMENT OF INTEGRATED ANALYTIC NETWORK PROCESS (ANP) AND THEORY OF INVENTIVE PROBLEM SOLVING (TRIZ) IN THE CONCEPTUAL DESIGN SELECTION

The production rate growing rapidly as the high demand of the product keeps increasing in the manufacturing industry. However, these can contribute to the inefficiency, low-quality product and limitation of the design product with timeconsuming delivering the performance and requirement to the customers. The objective of this paper is to develop the integrated Analytic Network Process (ANP) and Theory of Inventive Problem Solving (TRIZ) in the Conceptual Design Selection. ANP and TRIZ were represented as a multi-criteria decision making and an inventive problem solving respectively to perform a new integrated framework by considering the product requirements and the contradiction problems simultaneously. A case study of a manual wheelchair in selecting the best design concept was conducted. The result shows design concept 1 was selected as the best design concept with the highest value of 0.304 (30.4%). From the case study conducted, the application of integrated TRIZ and ANP was verified and the best design concept of a wheelchair was determined
