6 Conclusion and Further Work
Fuzzy approaches for human-centred problems seem to be quite flexible, hence in this
work we introduce a preliminary version of a qualitative method for RAH&S, in the
construction industry, using fuzzy logic concepts and techniques. From all pointed
limitations and inadequacies of traditional RAH&S methods it seems that using this
type of fuzzy approach, to evaluate work safety factors, yields a more realistic representation
and solution for evaluation of risks in the construction industry.
The outlined qualitative model (QRAM) is still under development. It needs to be
further improved and refined, such as identifying other types of hazards and further
characterize all risks involved, as well as to set criteria for the tolerability of risk
analysis in construction sites. After these improvements it needs to be tested and validated
with real case studies to assess its suitability and generality for the construction
sector.
