Abstract

In recent years, the rising competitive environment with shorter product life cycles and high customization forces industries to increase their flexibility, speed up their response, and enhance concurrent engineering designs. To integrate these prospects, supply chain collaboration becomes a pertinent strategy for industries to strengthen their competitiveness. The network design problem is used to implement supply chain collaboration. In the buying and selling process, sharing information between buyer and supplier are important to obtain a transaction decision. The optimimum supply chain profit can be identified by mathematical model of network design problem. The Mathematical Model takes into consideration the uncertainity in negotiation of supply chain, transportation problems, and locationallocation of products from supplier to buyer in the planning based on the time value of money. The results show that the model can be used to optimize the supply chain profit. The supplier gets a profit because income were received in the initial contract, while the buyer profit comes from lower pay.

Bahasa Abstract

Optimalisasi Kolaborasi Rantai Pasok berdasarkan Perjanjian Hubungan Pembeli-Pemasok dengan Masalah Desain Jaringan. Pada beberapa tahun terakhir, telah terjadi peningkatan perubahan lingkungan industri, yaitu siklus hidup produk yang lebih pendek dan adanya dorongan industri harus memeliki kekuatan spesifik agar mampu meningkatkan fleksibilitas, respon pasar, dan meningkatkan kemampuan integrasi desain semua desain proses produk. Untuk mewujudkan peluang ini, kolaborasi rantai suplai menjadi pilihan strategi bagi industri agar dapat memperkuat daya saing mereka. Desain jaringan dapat digunakan pada perbaikan kolaborasi rantai suplai. Dalam proses jual beli, berbagi informasi antara pembeli dan pemasok penting untuk mendapatkan keputusan transaksi. Keuntungan rantai pasokan yang optimum dapat diidentifikasi dengan model matematika dari masalah desain jaringan. Model Matematika yang dikembangkan mempertimbangkan ketidakpastian dalam negosiasi rantai pasokan, masalah transportasi, dan lokasi-alokasi produk dari pemasok kepada pembeli dalam perencanaan dengan mempertimbangkan nilai waktu dari uang. Dari hasil penelitian diketahui bahwa model dapat digunakan untuk mengoptimalkan keuntungan rantai pasokan. Pemasok mendapat keuntungan karena pendapatan yang diterima dalam awal kontrak, sedangkan keuntungan pembeli berasal dari pengeluaran biaya yang lebih rendah.
