由於平均壽命增加且現代醫學提高人類因受傷、生病與出生 缺陷的存活率,人們逐漸關注通用設計議題。『通用設計』 是一項用於發展產品及環境的方法,使其在最大程度範圍 內,能被所有人使用。雖然現行通用設計原則可以提供明確 的設計指引參考,但由於僅具條列式質化描述屬性,不易以 科學量化方式,準確評估產品之通用設計優劣。本研究提出 一套模糊語言方法用於評估產品通用設計,本方法利用模糊 語言變數結合模糊加權平均法,進行喜好度資訊之聚積運 算。為了說明方法之實用性,本研究以簡單的層級結構作決 策個案,執行產品選項評估,而個案結果呈現相當可靠度。本研究所提出的模糊語言方法可以有效協助處理具質化屬性 之複雜決策評估問題。 As life expectancy rises and modern medicine increases the survival rate of those with significant injuries, illnesses, and birth defects, there is a growing interest in universal design. Universal design is an approach of developing products and environments to be usable by all people, to the greatest extent possible. Although a set of acknowledged principles has been developed and commonly used by industry and academic community, it is difficult to quantitatively assess whether a product is indeed a good example of universal design. This study presents a fuzzy linguistic approach for universal design assessment. The proposed approach is based on fuzzy linguistic variables associated with the fuzzy weighted average techniques for aggregating preference information. To illustrate the practicability of the proposed approach, a case study using a simple hierarchy structure to assess product alternatives was conducted. It has shown a credible result. The fuzzy linguistic approach has proven to be useful in dealing with complex assessment problems involved in qualitative attributes.
