Özet:
Inefficiency
and waste permeate the construction industry, manifesting as extended
timelines, inflated costs, and suboptimal resource utilization. Lean
construction principles, however, offer a promising paradigm shift, enabling
process streamlining and enhanced productivity. This research delves into a
crucial question: to what extent can lean tools demonstrably improve
construction efficiency, productivity, and performance compared to traditional
methods? By adopting a rigorous simulation modeling approach, this study
utilizes Discrete Event Simulation Approach to develop comprehensive models
encompassing both baseline (conventional) and lean scenarios. By meticulously
comparing these models, statistically significant insights were generated into
the effectiveness of integrating lean techniques. The findings provide
compelling evidence for the transformative power of Lean in improving project
outcomes. Applying key principles like value specification, value stream
mapping, value flow, pull production, and continuous improvement resulted in
significant performance gains, while optimizing process and operational aspects
further reduced project total time, solidifying the benefits of a leaner
approach. Lean models demonstrated a 7.79%
increase in process efficiency and a 30.29% reduction in cycle time
for the retaining wall construction process, Moreover, the research transcends
mere potential demonstration by quantifying the measurable impact of
implementing specific lean tools, providing construction practitioners with
clear evidence of their effectiveness, and developing practical guidelines for
seamlessly integrating lean thinking into established management approaches,
bridging the gap between theory and practice.
