“…The FWA method has been seen as an aggregated function for handling MCDM group decision problems based on fuzzy sets theory, and it has been successfully applied in many fields such as engineering, Tee and Bowman [28], Wang and Chang [31], Lin and Chang [21], Zhou [33], Vanegas and Labib [29], Chen et al [7], Wang et al [32], Vanicek et al [30], Zou and Xiao [35], Hermans et al [15], Liu et al [24], Ma et al [26], Zhu et al [34] and management science, e.g., Hon et al [16], Kao and Liu [17], Avineri et al [1], Lin et al [20], Liu [25], Ghazinoory et al [10] and Noor-E-Alam [27].…”

“…The crisp number is normalized to achieve criteria values that are unit-free and comparable among all criteria. The normalized crisp values of W ij are calculated as expressed in the following equation (Karsak 2002): Wang and Chang (1995) and used in Chen (2000) Triangular fuzzy membership functions 1.0 0 0.1 0.3 0.5 0.7 0.9 1.0…”

Environmental practices in knowledge management capability (EKMC) is a complex and uncertainty concept that is difficult to determine based on a firm's real situation because measuring EKMC requires a set of qualitative and quantitative measurement. The objective of this study is to develop a cause and effect model in uncertainty using the fuzzy set theory and Decision Making Trial and Evaluation Laboratory (DEMATEL) method. A framework for evaluating EKMC is proposed. An approach of fuzzy linguistic is proposed to evaluate the firm EKMC. The evaluation results of EKMC obtained through the proposed approach are objective and unbiased due to two reasons. Firstly, the results are generated by a group of experts in the presence of motile attributes. Secondly, the fuzzy linguistic approach has more advantage to reduce distortion and losing of information. Through evaluating the result of EKMC, managers could judge the necessity to improve the EKMC and determine which criteria are the needed directions to improve. The managerial implication and conclusions are discussed.

“…After obtaining evaluation indices bj (j =1,2,…,n) , the concrete results of the target of evaluation can thus be confirmed based on the method of maximum DOM and WA method, and they are explained as follows (Wang, 1995;Farzaneh, 2008).…”

The objective of this study is to provide industrial design students with a comprehensive approach of product evaluation during the course of a research project. During the design evaluation stage, a student often encounters vague information since the attributes of product design demands are usually not quantifiable. Therefore, one of the important topics during the product development processes is to allow a student to carry out design evaluations effectively. The fuzzy Analytic Hierarchy Process (AHP) was utilized in this study to assess product designs and resolve the problems that might occur during product assessments. The purposive sampling technique was used in the questionnaire survey. By assigning a weighted value to each of the evaluation criteria, the case study verified the feasibility of the proposed design approach in fan designs. A total of 52 questionnaire copies were distributed. 36 copies of them were collected and the return rate is 77%. Among them, 28 copies were from the engineers and 8 copies were from people in the relevant industries. 22 copies were from males and this accounts for 61%. On the other hand, 14 copies were from females and this accounts for 39%. The results indicated that the weight of efficiency which is the secondary constituent element is the highest. Under the constituent element of efficiency, the weight of fan flow rate is 0.592 which is the highest. The defuzzification of efficiency is 0.744 which is the optimal value among the indices of various factors. The defuzzified value of Design No.4 after defuzzification is 0.682 which is the optimal one among four design candidates. The results of this study demonstrated the feasibility of the proposed design approach. New fan styles can be effectively created by implementing this design approach. This approach allows the entire evaluation process to be more precise. The combination of these approaches is not only practical and objective, but also is capable of assisting a student in making a decision under complicated and uncertain circumstances. This makes a design task definite and better clarified and also enhances a student's learning competitiveness by supplying a good reference during the follow-up stage of product design assessments.
