In this paper, the authors describe an application of fuzzy logic in analysis of delays in construction projects using Fuzzy toolbox of MATLAB Program Software. Delays in construction projects are inevitable and may result in claims and disputes among different construction parties. Delays in construction projects can be due to a number of causes, which need to be classified and identified. For the success of a construction project, estimation of likelihood of delay resulting from different factors is a must. Fuzzy logic provides a simple way to arrive at a definite conclusion based upon vague, imprecise or missing input information. Fuzzy logic is a form of many-valued logic; it deals with reasoning that is approximate rather than fixed and exact.
