Housing area safety evaluation (HASE) based on fuzzy grey theory / Maisarah Abd Kadir, Maria Kamilah Mohamad@Mohd Othman and Nurizzati Zulkhaire

Safety evaluation in housing area is very important to reflect the safety performance of
the research. In this study, safety evaluation is proposed based on Fuzzy Grey Theory
(FGT) and Analytical Hierarchy Process (AHP) to determine the level of safety at the
selected housing areas. The purpose of this study is to create safety evaluation for housing
areas based on AHP and FGT and implement the proposed method to determine the level
of safety at selected housing areas. There are some phases to determine rankings and
safety evaluation at the housing areas. Starting from the first phase, which is to determine
the weight for each criterion by using AHP method, followed by determining the safety
level based on FGT. Then, safety evaluation for selected housing areas is determined by
using comprehensive weight of the FGT results from the earlier phase. Once the
calculation has been completed, safety levels are obtained, and the results are later
validated by experts. The finding shows that the results are consistent with the expert
opinion and it can be used by general public when choosing suitable houses for renting or
buying new property.
