Displays generally located into cars' dashboard are important equipment in terms of driving safety and interior design of cars. In the industry, there are various display designs. Some of them may have positive impacts on customers while some of them may not. The selection of design parameters such as location of displays (behind steering wheel or on the center console), colors (for background and symbols/lettering), types (digital or analog), and shapes (circle, semicircle, or quadrangle) diversify display designs in the industry. In this paper, a design evaluation model (DEM) has been proposed to the relevant literature. The design characteristics of display and priorities of design parameters of displays are put forward by using the proposed model. DEM is an integrated method including fuzzy analytic hierarchy process and fuzzy Choquet integral. The fuzzy analytic hierarch process (AHP) is utilized to define the priorities of design parameters of displays by using subjective assessment of customers while fuzzy Choquet integral is used to determine design characteristics of displays by using linguistic evaluations of design team. . (e.g., frontal collision warning, night vision support, parking aids, and adaptive cruise control) increases [1].A car display includes various gauges such as speedometer, a fuel gauge, a tachometer, charging system gauge, oil pressure gauge, and engine temperature gauge. Those days, car manufactures also provide a road computer and global positioning system as a standard. The objectives of gauges used in a display design are to provide state information, to give advice, and to present warnings. Indicators and hazard lights provide drivers the state of controlled functions such as speed and tachometer. Fuel low, fuse failure, and brake pads worn are advisories which caution drivers that vehicle needs attention in the near future. The warnings such as high engine temperature, low oil alert drivers that vehicle needs immediate attention. The information given by displays must be provided in the correct format on the correct time to make easy and quick understandable of the information [2]. Nowadays, manufactures produce displays in various forms and colors. The main
