Involvement has become an important variable in consumer behavior and marketing research for a long time. The purpose of this study is to develop a model that can explain the complicated relationship between antecedents, consequences, and different types of involvement at the same time to understand the internal state of consumers better. Specifically, this(More)
QUALIFLEX, a generalization of Jacquet-Lagreze’s permutation method, is a useful outranking method in decision analysis because of its flexibility with respect to cardinal and ordinal information. This paper develops an extended QUALIFLEX method for handling multiple criteria decision-making problems in the context of interval type-2 fuzzy sets. Interval(More)
Leaf explants of Paphiopedilum phiIippinense hybrids (hybrid PH59 and PH60) directly formed adventitious shoots from wound regions within 1 month, when cultured on modified Murashige and Skoog medium (1/2-strength macro- and full-strength micro-elements) free of plant growth regulator in darkness. The combinations of 2,4-dichlorophenoxyacetic acid ((2,4-D)(More)
The data collection and identi cation of -fuzzy measures are fundamental tasks to be capable of using them in practice. Although several studies have been made on -fuzzy measure identi cation, their methods require the knowledge of subjective estimates for all subsets of an attribute set, or the corresponding computation process is rather complicated. Since(More)
Since a particle swarm optimization (PSO) algorithm uses a coordinated search to find the optimum solution, it has a better chance of finding the global solution. Despite this advantage, it is also observed that some parameters used in PSO may affect the solution significantly. Following this observation, this research tries to tune some of the parameters(More)
