چکیده انگلیسی:
The estimate of construction waste generation is the key decision-making information for policy-makers,
construction managers, and the like to devise informed waste management strategies. However, estimating
construction waste generated from projects is particularly onerous, as numerous factors related
to design, site, and construction are largely in a fuzzy nature when the estimating job is conducted. Built
upon previous studies, this paper seeks to develop a model that can be used to estimate construction
waste generation based on fuzzy set theory. It follows a trilogy of methodology, including model
development, sensitivity analysis, and model validation. A set of IF-THEN rules are developed based on
two independent variables, built area and number of floors. A sensitive analysis was conducted to
evaluate the influence of the independent variables on waste generation. The model is further calibrated
and verified through a case study of 23 residential buildings constructed in the Brazilian Amazon. The
model obtained an accuracy of 64.29% in the development phase and 66.67% in the validation phase,
showing that the results are largely acceptable. By using this model, it is possible for a waste manager to
draw up a baseline graph to indicate the volume of construction waste generation as his/her building
project as it progresses. The research is also of novelty by using fuzzy set theory to deal with the fuzzy
nature of waste generation in construction projects. Further studies are recommended to enhance the
accuracy level of the model by engaging more factors and more quality data.
