Sustainable sourcing strategy for mega construction projects: An empirical analysis

Abstract

Time and cost overruns are the prominent issues faced by mega construction projects. To minimize cost overruns for the projects, a stepwise approach is suggested for the formulation of a sustainable sourcing strategy. Initially, weights are derived for the existing suppliers using the analytic hierarchy process to select the best set of suppliers. Multiple conflicting variables are considered for deriving the weights. Based on the derived weights, the supply network cost optimization model is developed for optimal order quantity allocation to the selected suppliers to maximize total purchasing value (TPV). A multi‐objective weighted goal programming model is used to minimize deviations in the TPV. Finally, the full factorial design of the experiment concept is employed to identify the significant factors impacting deviations in TPV. The methodology developed is verified using a case study approach. Mega‐construction project organization case was considered for analysis. Demand for the product, materials procurement cost, quality, and supplier lead time are found to be the significant factors impacting deviations in TPV. The developed approach can provide valuable insights to practitioners for the formulation of a sustainable sourcing strategy.

Economic asymmetries and the new “markets of tomorrow”

“…This article's contribution to the literature is developing a business strategy and concept that rethinks their specificities in the new markets of tomorrow. The article also confirms ongoing analyses (Bagul et al, 2023;Patil & Vhavale, 2023;Setiarini et al, 2023;Sharma & Bhat, 2023)…”

“…Specifically, it examines the economic asymmetry of new markets and how it leads to differences in digitalization and competitiveness among countries. This article is mainly concerned with identifying these disparities and their implications for the future (Bagul et al, 2023;Patil & Vhavale, 2023;Setiarini et al, 2023;Sharma & Bhat, 2023). Ndalamba (2019) has explored the problematic public policies and the leadership challenge for South Africa's socioeconomic transformation.…”
