In a groundbreaking study that promises to revolutionize the construction sector, researchers have developed a comprehensive integrated subjective–objective criteria weighting multi-criteria decision-making (MCDM) model for optimizing formwork material selection. The lead author, Tamene Taye Worku from the Commercial Bank of Ethiopia, emphasizes the importance of this approach in addressing the significant costs associated with formwork systems, which are often labor-intensive and complex to navigate.
Formwork systems, essential for shaping concrete structures, account for a substantial portion of construction expenses. Worku’s research highlights that the traditional methods of selecting formwork materials often fail to consider the multifaceted nature of decision-making, leading to inefficiencies and increased costs. “Our model integrates both subjective and objective criteria, allowing for a more nuanced understanding of the various options available,” Worku explains.
The study employs a robust methodology, beginning with the development of a Likert-type fuzzy number (LFN) questionnaire, refined through Delphi and interview techniques. This initial phase ensures that the criteria for evaluating formwork materials are both comprehensive and relevant. Subsequently, the researchers utilized a combination of correlation analysis and a thorough literature review to select the most pertinent MCDM methods and criteria weights.
One of the standout features of this research is the Monte Carlo Simulation, which ranks formwork options based on a 95% performance score. The findings reveal that aluminum is the most preferred formwork material, with steel, plastic, and timber following closely behind. Worku notes, “While aluminum stands out, our analysis suggests that combining aluminum with steel and plastic can maximize benefits, offering a strategic advantage in construction projects.”
The implications of this research extend beyond mere academic interest; they carry significant commercial potential. By optimizing formwork material selection, construction companies can reduce costs, enhance efficiency, and ultimately improve project timelines. This could lead to more competitive bidding and increased profitability in a sector that is constantly striving for innovation.
As the construction industry grapples with rising material costs and labor shortages, Worku’s comprehensive MCDM model presents a dynamic tool for navigating these challenges. The study, published in ‘Discover Materials’ (translated as ‘Discover Materials’), is poised to influence future developments in the field, encouraging a shift towards more data-driven decision-making processes.
With the construction industry evolving rapidly, the integration of sophisticated decision-making frameworks like the one proposed by Worku could pave the way for a new era of efficiency and sustainability. As stakeholders look for ways to optimize resources, this research serves as a timely reminder of the power of informed decision-making in shaping the future of construction.
