Comparing Rough Set Theory with Multiple Regression Analysis as Automated Valuation Methodologies
This paper focuses on the problem of applying rough set theory to mass appraisal. This methodology was first introduced by a Polish mathematician, and has been applied recently as an automated valuation methodology by the author. The method allows the appraiser to estimate a property without defining econometric modeling, although it does not give any quantitative estimation of marginal prices. In a previous paper by the author, data were organized into classes prior to the valuation process, allowing for the if-then, or right âruleâ for each property class to be defined. In that work, the relationship between property and class of valued was said to be dichotomic.mass appraisal; property valuation; rough set theory; valued tolerance relation
Deriving consensus rankings via multicriteria decision making methodology
Purpose - This paper seeks to take a cautionary stance to the impact of the
marketing mix on customer satisfaction, via a case study deriving consensus
rankings for benchmarking on selected retail stores in Malaysia.
Design/methodology/approach - The ELECTRE I model is used in deriving
consensus rankings via multicriteria decision making method for benchmarking
base on the marketing mix model 4P's. Descriptive analysis is used to analyze
best practice among the four marketing tactics.
Findings - Outranking methods in consequence constitute a strong base on
which to found the entire structure of the behavioral theory of benchmarking
applied to development of marketing strategy.
Research limitations/implications - This study looks only at a limited part
of the puzzle of how consumer satisfaction translates into behavioral outcomes.
Practical implications - The study provides managers with guidance on how to
generate a rough outline of potential marketing activities that can be used to
take advantage of capabilities and convert weaknesses and threats.
Originality/value - The paper interestingly portrays the effective usage of
multicriteria decision-making and ranking method to help marketing managers
predict their marketing trends
Haptic Hybrid Prototyping (HHP): An AR Application for Texture Evaluation with Semantic Content in Product Design
The manufacture of prototypes is costly in economic and temporal terms and in order to carry this out it is necessary to accept certain deviations with respect to the final finishes. This article proposes haptic hybrid prototyping, a haptic-visual product prototyping method created to help product design teams evaluate and select semantic information conveyed between product and user through texturing and ribs of a product in early stages of conceptualization. For the evaluation of this tool, an experiment was realized in which the haptic experience was compared during the interaction with final products and through the HHP. As a result, it was observed that the answers of the interviewees coincided in both situations in 81% of the cases. It was concluded that the HHP enables us to know the semantic information transmitted through haptic-visual means between product and user as well as being able to quantify the clarity with which this information is transmitted. Therefore, this new tool makes it possible to reduce the manufacturing lead time of prototypes as well as the conceptualization phase of the product, providing information on the future success of the product in the market and its economic return
Emotional Qualities of VR Space
The emotional response a person has to a living space is predominantly
affected by light, color and texture as space-making elements. In order to
verify whether this phenomenon could be replicated in a simulated environment,
we conducted a user study in a six-sided projected immersive display that
utilized equivalent design attributes of brightness, color and texture in order
to assess to which extent the emotional response in a simulated environment is
affected by the same parameters affecting real environments. Since emotional
response depends upon the context, we evaluated the emotional responses of two
groups of users: inactive (passive) and active (performing a typical daily
activity). The results from the perceptual study generated data from which
design principles for a virtual living space are articulated. Such a space, as
an alternative to expensive built dwellings, could potentially support new,
minimalist lifestyles of occupants, defined as the neo-nomads, aligned with
their work experience in the digital domain through the generation of emotional
experiences of spaces. Data from the experiments confirmed the hypothesis that
perceivable emotional aspects of real-world spaces could be successfully
generated through simulation of design attributes in the virtual space. The
subjective response to the virtual space was consistent with corresponding
responses from real-world color and brightness emotional perception. Our data
could serve the virtual reality (VR) community in its attempt to conceive of
further applications of virtual spaces for well-defined activities.Comment: 12 figure
