Risk quantification using fuzzy-based Monte Carlo simulation

Abstract: Estimating cost contingency of construction projects depends largely on data captured from previous projects and/or experience and judgment of members of project team. Mote Carlo simulation is commonly used in estimating contingency, where its accuracy was reported to depend on number of iterations used in the simulation process, probability density functions associated with each project cost item being considered and the correlation among these cost items. The literature reveals that the latter is the most im… Show more

“…The fuzzy set theory is used to represent the subjectivity of the input data provided by members of project team (Moselhi and Roghabadi, 2020). In this study, the model uses fuzzy sets to represent the uncertainty related to crew productivity rates and amounts of work in repetitive units.…”

“…The fuzzy set theory is a frequently used method for managing construction risks [20][21][22]. The fuzzy representation of linguistic terms can capture the vagueness and imprecision associated with the input data provided by the participants [23].…”

“…If the model is complex with many stochastic variables, theoretical analysis will be relatively difficult. In this case, the MC simulation [21,22] can be introduced to easily compute the probability of each drilling risk. Hence, this paper selects MC simulation to determine the drilling risk probabilities.…”
