A gid utility-based model for interior renovations selection

Abstract

Due to the natural environment and the consumption of the earth's resources, the ecological damage and resource depletion have become a serious problem facing the world in recent years. To understand the design process of the interior decoration and its associated environmental issues, a plan was developed on how to introduce the green interior design concept with a view of creating a safe, healthy, green low-carbon and high-quality living space, where The FDM, AHP and cloud theory were used to deal with complex interior renovations decision issues mainly due to information uncertainty, time lapse and complexity of the problems, with, therefore, the feature cloud model employed to analyse multi-stage risk decision problems. The research results enabled customers to make decisions quickly without relying on the personal experience and ability of designers and experts. The GID decision model verified the feasibility and rationality of the method proposed in this study, which, having high analysis ability was capable of accurately predicting decisions.

Cib - Utility Based Systems Framework for Existing Residential Building

“…After analysis, daily energy-saving (BEP2) electricity use and commuting were found to play crucial roles in the majority of the categories of sustainability impact. Daily energy-saving electricity use is one of the most dominant components of environmental impacts, with more than 50% of greenhouse gas emissions and energy consumption throughout the life cycle stages of buildings in Taiwan (Chiang et al 2020). The construction phase has the largest share in the income category, with 60% of the total income generated through the life cycle of residential buildings (Farahani, Wallbaum, and Dalenbäck 2019a).…”

“…It is frequently applied for decision analysis in fields related to sustainability, the environment, economics, business, management, engineering, management consulting, etc. (Chiang et al 2020;Saaty 1990Saaty , 2008, e.g., the indoor environment assessment (Chiang and Lai 2002); real estate developer's product positioning (Chiang 2019); sustainability (Mardani et al 2017) and sustainable system (Rehman and Ryan 2018).…”

“…After defining the fuzzy scale for yH; yL ð Þ and the values for y mi andy ma ð Þ, the constants A and B, as well as the utility function for each criterion, can be obtained by solving Equation (2). As an example, relevant utility theory-related research includes risk management (Chiang et al 2020), the product positioning of real estate developers was considered (Chiang 2019). The causal relationships within the overall industrial structure and the complex factors in the system environment were taken into account in the modeling process.…”

“…The FDM utilised triangular fuzzy numbers to integrate the perceptions of experts and scholars and improve the limitations of the traditional Delphi method, which could only provide 50% of the information because of the use of a repeated questionnaire survey. The FDM can semantically express meaning more precisely (Chiang et al 2020).…”

“…Ishikawa et al (1993) integrated expert opinions with fuzzy numbers based on the concepts of cumulative frequency distribution and fuzzy integral. Chiang et al (2020) revealed that when FDM is applied for the factor, the threshold can be reduced when decision makers identify few measurement indicators; otherwise, screening can be performed to remove factors with a low discrimination index. We used Microsoft Excel for the pre-test analysis following.…”
