the growing complexity of supply chains in construction projects, along with the frequent occurrence of material theft an‎d loss, underscores the necessity of employing advanced technologies for material tracking an‎d control. This study emphasizes the role of RFID technology in preventing such disruptions an‎d ensuring faster material delivery to project sites, ultimately reducing activity start times an‎d enhancing execution efficiency.This research develops a single-objective mathematical model for the optimal allocation of RFID equipment within construction project supply chains. The objective of the model is to minimize total costs by focusing on reducing delivery times an‎d improving the scheduling of project start times. The model is formulated in both deterministic an‎d non-deterministic settings. In the non-deterministic case, the Bertsimas an‎d Sim robust optimization framework is incorporated to capture fluctuations in transportation times.Numerical results demonstrate that the optimal objective function value is 1520 in the deterministic scenario an‎d 1538 in the robust scenario. This deviation illustrates the adverse impact of temporal uncertainties on system performance. Despite this, optimal RFID allocation leads to a four-day reduction in overall supply chain duration an‎d a decrease of 105 units in total project costs.Further analysis identifies nodes 1 an‎d 5 as critical bottlenecks, where RFID installation yields the highest improvements in reducing delays an‎d enhancing supply chain resilience. Overall, the proposed model provides a practical an‎d effective decision-support tool for minimizing costs an‎d delivery times, strengthening material security, an‎d improving reliability of construction supply chains under uncertainty.
