Abstract: Penentuan lokasi hub yang optimal dalam sistem logistik sangat penting untuk meminimalkan biaya operasional dan meningkatkan efisiensi distribusi. Penelitian ini membahas masalah lokasi hub single assignment dengan mempertimbangkan tingkat kapasitas ganda untuk mengatasi keterbatasan kapasitas hub dalam memenuhi permintaan pelanggan. Pendekatan ini memastikan setiap node non-hub terhubung ke satu hub, sementara tingkat kapasitas ganda memberikan fleksibilitas dalam alokasi sumber daya. Model matematis dikembangkan untuk meminimalkan biaya total yang mencakup biaya tetap pembukaan hub, biaya transportasi, dan biaya operasional hub. Penyelesaian dilakukan menggunakan metode eksak meskipun akan diimplementasikan dalam skala yang relatif besar. Hasil simulasi menunjukkan bahwa penggunaan tingkat kapasitas ganda dan single assignment menghasilkan konfigurasi jaringan yang lebih efisien dan fleksibel dalam menentukan lokasi hub.
Determining optimal hub locations in logistic systems is crucial to minimizing operational costs and improving distribution efficiency. This study addresses the single assignment hub location problem by incorporating multi-capacity levels to overcome hub capacity limitations in meeting customer demand. This approach ensures that each non-hub node is connected to only one hub, while multi-capacity levels provide flexibility in resource allocation. A mathematical model is developed to minimize total costs, including fixed hub opening costs, transportation costs, and hub operational costs. The solution is obtained using exact methods, despite being implemented on a relatively large scale. Simulation results show that the use of multiple capacity levels and single assignment leads to a efficient and flexible network configuration for determining hub locations.
