Computerized DSS for construction conflict resolution under uncertainty

Due to the inherent nature of construction projects, conflicts are unavoidable among the various parties involved. Such conflicts often delay projects and cause losses for all parties. This paper presents the development of a decision support system (DSS) to help in resolving construction disputes. The DSS integrates the elimination method to shortlist promising resolutions to a conflict, the graph model for conflict resolution to determine the best resolution that satisfies all decision makers' preferences, and the information gap theory to consider uncertain decision preferences. A prototype system has been developed and a case study of a construction conflict used to demonstrate its features. The presented methodology for construction conflict resolution is useful for both researchers and practitioners to better deal with the dispute-prone nature of the construction industry under uncertainty and lack of information. In this paper, the proposed prototype successfully simulated and predicted the sequence of decisions that took place in the case study dispute, in the presence of uncertainty.
