  • The present study compared the two experimental methods on inquiring the image structure of odors: Presenting a stimulus is one, and not presenting a stimulus is the other. For experiment one, five odors were presented, and the subjects were instructed to evaluate the odors on 7-point scale for each of the 25 adjectives. For experiment two, no odor was presented, and the subjects were instructed to perform the pair-wise comparisons for the each pair of two adjectives on their similarities on 7-point scale. The data from the two experiments were analysed and compared using MDS(Multi-Dimensional Scaling), Correlation, Cluster Analysis. The results showed that there was no structural differences between two experimental methods in term of the Image structure of odors. But, minor disparity was found between two methods in terms of density of distribution of the adjectives. It was construed that the difference came from the difference of the memory that was used for each of the experiments; that is, short term memory for experiment one and long-term memory for experiment two.

  • Despite the increasing interest in web contents and the rapid growth of CMS(Content Management System) market, the studies on the evaluation criteria for determining the purchase of the CMS solution are very rare. We introduce previous researches on the evaluation models of IT solution, and develop new criteria for evaluating CMS solutions. We calculate the relative importance of the evaluation criteria using scores from the IT experts based on the "Pair-wise Comparison" using the AHP. Based on the analyses of IT specialists′ responses, the results of the study show that, among the ten criteria, "the function of content management", "the contribution to the company′s business process" and "the fit with Information Strategic Plan" are the three most important ones over the remaining others. The developed model and criteria for the evaluation of the CMS solutions are expected to contribute on effective purchasing decision of the solutions and their successful implementation.

  • This study is aimed to design a priority setting algorithm necessary for evaluating and selecting interdependent R&D planning system alternatives. In case that the relationship of technology alternatives is interdependent, a relative importance as occurrence or nonoccurrence of the technology alternatives viewed from the future time varies. So, we are subject to design the evaluation process considering a cross- impact of future technology alternatives. Thus, we apply the cross impact analysis (CIA) model to consider the cross-impact among interdependent system alternatives. Also, the analytic hierarchy process(AHP) model is applied to determine the priority of alternatives by taking the pair-wise comparison among factors.

  • This study proposed a Rural Amenity Values Assessment Model (RAVAM) to evaluate the rural amenity resources based on the Myun as a spatial unit. In RAVAM, 61 rural amenity resources were classified into almost intact nature resources, interaction between nature and man resources, man-made resources, respectively. Especially, Rural Scenic Value Index (RSVI) was developed to quantify rural scenic views as a rural amenity resource. RSVI was utilized in evaluation process of rural amenity resources. The weighing factors for the amenity resources were evaluated from the step wise pair-comparison results of 11 specialists by Analytic Hierarchy Process(AHP). In the results, the weighting values of almost intact nature resources, interaction between nature and man resources, man-made resources were 496, 323 and 181, respectively, among total value being 1,000.

  • Using the computer simulation method, we invest19ate the probability distribution of maximum eigenvalue of pair-wise comparison matrix, which has been used as a parameter for measuring the consistency of responses in analytic hierarchy process (AHP). We show that the shape of the distribution of the maximum eigenvalue is different according to the dimension of the matrix. In addition, we cannot find any evidence that the distribution of the Consistency Index is a Normal distribution, which has been claimed in the Previous literature. Accordingly, we suggest using so called K-index calcu1ated based on the concept of cumulative distribution function lather than based on that of arithmetic mean because the probabilistic distribution cannot be assumed to be a Normal distribution. We interpret the simulation results by comparing them with the suggestion of Saaty[11]. Our results show that using Saaty's value could be too generous when the dimension of the matrix is 3 and strict over 4. Finally, we propose new criteria for measuring the response consistency in AHP.

  • As disposal packaging concepts of spent fuels generated from the domestic NPP, two types, one is to package PWR and CANDU spent fuels in different containers and the other is to package them together, were proposed. The configuration of the containers and the layout of underground repository, such as the container spacing and the deposition tunnel spacing, were developed. The layout of underground repository satisfies the thermal constraint of the bentonite buffer surrounding disposal container, which should be lower than $100^{\circ}C$ in order to keep the physical and chemical properties of bentonite From the spent fuel packaging concepts and container emplacement methods, seven options were developed. With a typical pair-wise comparison methods, AHP, the most promising disposal concept was selected based on the technology Point of view.

  • Wrinkle and fracture are two major defects frequently found in the sheet metal forming process. In this process there are more than one design attributes to optimize and several uncontrollable factors which cannot be ignored in determining the optimal values of design variables. Therefore, attempts to reduce defects through a traditional optimization technique are often led to failures. In this research, a new design method for reducing the wrinkle and fracture under uncontrollable factors is presented by using decision-making theory. To avoid the psychological difficulties in determining the scaling constants of the multi-attribute utility function by using the ordinary lottery questions, a pair-wise comparison procedure is adapted to avoid this problem. The effectiveness of the proposed method is illustrated through a robust design of sheet metal forming process of a side member of an automotive body.

  • The objective of this study is to identify the critical dimensions of comprehensive quality and to prioritize them for improvement of the quality competitive advantage. The critical dimensions, sub-dimensions and measurement items of comprehensive quality were abstracted from literature of quality, and constructed a model of hierarchical structure. 115 experts in four groups(supplier, buyer, consultant, and professor) were participated in pair-wise comparison of quality dimensions, but some of these responses were removed because the overall consistency of evaluator judgements exceed the acceptable ratio of 0.10. The priorities of quality dimensions for industrial and consumption goods were calculated respectively using the analytic hierarchy process(AHP) approach. As a result, product quality had the highest weight of 0.65, followed by support quality(0.18) and service quality(0.17) for industrial goods while product quality also had the highest weight of 0.62, but service quality(0.22) was preferred over support quality(0.16) for consumption goods.
