A fuzzy sets model for construction dispute evaluation

Unresolved construction dispute can be detrimental to project success. A systematic method to evaluate the seriousness of construction dispute of a construction project will assist management to take appropriate corrective actions. Evaluation of construction disputes requires an analysis on both the likelihood of occurrence and its impact, which are normally expressed by practitioners in linguistic terms. The application of classical discrete analysis will not be able to accommodate the fuzzy nature of this information. To determine how fuzzy sets theory can be applied to construction disputes evaluation (CDE), a fuzzy CDE model has been developed based on the knowledge extracted from practitioners in Hong Kong. The fuzzy CDE system consists of four components: dispute identification, dispute analysis; dispute evaluation; and dispute control. This paper describes the framework and operation of the fuzzy CDE system developed. The results indicate that CDE can be modelled by the fuzzy sets theory.
