Whist Game Cards Calibration Strategies-Based Technique for Conceptual Design Morphological Chart Refinement

High-quality concept design is a key factor of successful product performance and efficiency. Conventional conceptual design morphological chart serves to combine product concept designs. Nevertheless, the huge number of combined concept designs and how to reduce is an important research point. In this paper, concepts design combined after refinement of possible sub-functions means (M) in the product conceptual design morphological chart to less and most promising means based on calibration proceeded in binary for the means regarding numerical scales applied to a package of quality attributes (QAs). The calibration proceeds in accordance with single suit whist game between two competitors’ strategies. The game tricks number depends on QAs number, and the summation of tricks scored by each means give M numerical value. Means with the high numerical values keep existence while means with the weak numerical values were eliminated from the chart. The case study approved the current technique reliability and flexibility for assessing sub-functions means which accommodates a wide variety of QAs to solve the problem of useless and abundance concepts design through morphological chart refinement. In addition, these capabilities make designers able to specify more QAs to meet different product stakeholders’ requirements. Beside these advantages, the opportunities for further development and limitations are considered in discussion and conclusion.
