چکیده :

Information transparency is increasingly important in distribution network design, particularly in sensitive supply chains where product traceability and visibility are essential. This study develops a two-echelon multi-commodity location model that integrates transparency into strategic network design decisions. The proposed model simultaneously determines distribution center locations, customer assignments, commodity flows, and transparency activation decisions. Transparency is represented through link-specific transparency levels and transparent product flows, while a minimum transparency requirement is incorporated into the model. The objective is to minimize total network cost while satisfying the required transparency level. The resulting mixed-integer linear programming (MILP) model is implemented in GAMS and solved using solver CPLEX. A numerical example and sensitivity analysis are conducted to investigate the effects of transparency requirements on network configuration and total cost. The results demonstrate the trade-off between economic efficiency and information visibility and highlight the importance of explicitly incorporating transparency into distribution network design. The proposed framework provides a quantitative basis for designing transparent and cost-efficient distribution networks, particularly in sensitive supply chains.
