NETWORK DESIGN FOR SHORT AND LOCAL AGRI-PRODUCT SUPPLY CHAIN

ABSTRAK

Konsumsi produk pertanian buah dan sayuran menghadapi permasalahan yang semakin kompleks. Ini diakibatkan oleh preferensi konsumsi pelanggan serta kebijakan pemerintah yang memberikan prioritas produk lokal dibandingkan produk impor. Dalam hal ini rantai pasok yang terbentuk memiliki ciri khas unik dimana hanya terdiri dari pemasok petani distributor dan pelanggan. Rantai pasok ini disebut rantai pasok pendek dan lokal. Pemasok dapat mengirimkan produk mereka dengan maupun tanpa dukungan dari distributor. Sedangkan distributor dimungkinkan untuk mengirimkan langsung produk yang diterima ke pelanggan maupun mengirimkannya ke distributor yang lain. Untuk meminimumkan biaya transportasi permasalahan yang dibahas akan didasarkan pada tiga keputusan yaitu i pemasok mana yang akan mengirimkan barang ii distributor mana yang akan digunakan dan iii aliran produk sepanjang rantai pasok. Dengan menggunakan dekomposisi Benders yang didasarkan pada penelitian sebelumnya pendekatan ini akan diimplementasikan menghasilkan kode program yang handal untuk menyelesaikan masalah tersebut. Studi ini menggunakan pertidaksamaan valid dan relaxation constraints untuk meningkatkan solusi pada master problem. Data yang digunakan telah dibangkitkan berdasarkan data yang dikumpulkan pada departemen Isre Prancis. Hasil yang didapatkan menunjukkan bahwa menunjukkan bahwa penelitian sebelumnya menghasilkan range antara batas atas dan bawah yang tidak tepat pada beberapa data yang telah dibangkitkan. Sedangkan penelitian ini memberikan solusi yang lebih baik dengan mempertimbangkan waktu komputasi dan kualitas solusi terutama untuk data yang lebih besar


ABSTRACT

The consumption of Agri-product such as fruits and vegetables tends to be more complex due to customer tendency and government policy prioritizing local product consumption rather than imported product. The emerged supply chain called short and local supply chain has unique characteristics which involved only three echelons supplier farmer distributor and customer. The suppliers can deliver their products with or without the support of distributor and distributor could decide to transfer the product to another distributor. In order to minimize the transportation cost the problem is broke down into three decisions i decision for opening suppliers ii which distributors will be used and iii the flow of product from supplier to customer. Using extended Benders Decomposition based on Prieto 2012 the approach will be implemented in order to establish a set of reliable code which is able to solve the problem. This study uses valid inequalities and relaxation constraints to enhance the solution of master problem. The instances has been generated based on collected data from the research in Isre Department France for the sake of testing reliability of the extended technique. From the results it is found that previous research offers incorrect range of solution for some instances in order to estimate the value of optimal solution. This study proposes better solution regarding to the computational time and quality solution for larger instances.
