Determining Project Contingency Reserve Using a Fuzzy Arithmetic-Based Risk Analysis Method
Download2020-01-01
Fateminia, Seyed Hamed, Siraj, Nasir Bedewi, Fayek, Aminah Robinson, Johnston, Andrew
Traditional techniques for estimating contingency reserve fail to capture subjective uncertainties and expert knowledge, and they rely on historical data. This paper proposes a fuzzy risk analysis model (FRAM) that uses fuzzy arithmetic to analyze risk and opportunity events and determine...

Digitalization Opportunities Road Mapping Tool (DORMT©): A framework to assess digitalization opportunities in construction organizations
Download2021-04-13
Gebretekle, Yisshak Tadesse, Kamau, Daniel Waweru, Raoufi, Mohammad, Fayek, Aminah Robinson
The construction industry is entering the digital age, which offers innovative digitalization opportunities (DOs) regarding cost efficiency, project management, and improved client experience. In their early efforts to implement DOs, construction organizations have had varying degrees of success,...

Seresht, Nima Gerami, Fayek, Aminah Robinson
Construction productivity is a major research interest within the construction domain. Because construction is a labor-intensive industry, previous research has often focused on construction labor productivity (CLP). However, equipment is the main driver of productivity for some construction...

Evaluating Risk Response Strategies on Construction Projects Using a Fuzzy Rule-Based System
Download2019-01-01
Fateminia, Seyed Hamed, Seresht, Nima Gerami, Fayek, Aminah Robinson
The development and implementation of risk response strategies contributes to effective risk management processes in construction organizations. Risk response strategies need to be developed and implemented as follows: first, all possible risk responses for each given risk event of a project are...

Fuzzy Agent-Based Multicriteria Decision-Making Model for Analyzing Construction Crew Performance
Download2020-01-01
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...

Hybrid fuzzy Monte Carlo agent-based modeling of workforce motivation and performance in construction
Download2021-01-01
Raoufi, Mohammad, Fayek, Aminah Robinson
Purpose – This paper aims to cover the development of a methodology for hybrid fuzzy Monte Carlo agentbased simulation (FMCABS) and its implementation on a parametric study of construction crew performance. Design/methodology/approach – The developed methodology uses fuzzy logic, Monte Carlo...
