Raoufi, Mohammad, Fayek, Aminah Robinson
Recently, agent-based modeling (ABM) has been used to model construction processes and practices because it is capable of handling some of the complexities that arise from the interactions of system components. However, ABM alone cannot take into account the subjective uncertainty that exists in...

Kedir, Nebiyu Siraj, Raoufi, Mohammad, Fayek, Aminah Robinson
Selecting economically feasible policies for maximizing crew motivation and performance is a multifaceted problem, and each aspect of the process poses considerable unique challenges for construction practitioners. Fuzzy agent-based modeling (FABM) addresses some of the challenges of predicting...

Raoufi, Mohammad, Fayek, Aminah Robinson
Labor productivity and performance both significantly influence the overall success of construction projects, and the motivation of crew members is a major factor affecting labor. The construction industry needs better methods of measuring motivation and its impact on performance, which in turn...

Hybrid fuzzy system dynamics model for analyzing the impacts of interrelated risk and opportunity events on project contingency
Download2020-07-23
Siraj, Nasir B., Fayek, Aminah Robinson
Traditional risk analysis techniques are ineffective for capturing the dynamic causal interactions and subjective uncertainties involved in assessing risk and opportunity events since they treat risks independently and rely on the availability of sufficient historical data. In this paper, a...

Integrated FAHP-FDEMATEL for determining causal relationships in construction crew productivity modelling
Download2023-01-01
Kedir, Nebiyu, Fayek, Aminah Robinson
Construction crew productivity is affected by the motivation of the crew performing given activities and by situational/contextual factors forming the dynamic construction environment. The literature lacks a comprehensive analysis of causal relationships between crew motivation and...

Integrating fuzzy agent-based modeling and multi-criteria decision-making for analyzing construction crew performance
Download2019-01-01
Kedir, Nebiyu Siraj, Raoufi, Mohammad, Fayek, Aminah Robinson
Construction practitioners face considerable challenges when selecting economically feasible policies for maximizing crew motivation and performance. This paper proposes a methodology for integrating fuzzy agent-based modeling (FABM) with multi-criteria decision-making (MCDM) to develop a...
