Abstract

Perusahaan distibusi perlu merencanakan pengiriman yang efisien agar tidak mengeluarkan biaya pengiriman yang besar dengan meminimalkan biaya pengiriman. Oleh karena itu, perusahaan menerapkan masalah transportasi dalam memilih pola distribusi yang tepat untuk memperoleh biaya distribusi yang optimal. Masalah transportasi diterapkan untuk mengalokasikan produk yang sama ke tempat-tempat tujuan. Dalam permasalahan pendistribusian lebih dari satu produk, model masalah transportasi dimodifikasi sehingga dapat digunakan untuk mengoptimalkan biaya pengiriman. Data diperoleh dari toko Sejahtera meliputi data biaya distribusi, persediaan dari sumber dan permintaan setiap toko yang bertujuan untuk mengoptimalkan biaya distribusi menggunakan model masalah transportasi yang dimodifikasi. Analisis dilakukan dengan meramalkan permintaan produk yang diolah dengan proses \textit{time series} untuk membantu perusahaan dalam memperkirakan jumlah permintaan masing-masing produk untuk waktu yang akan datang. Kemudian melakukan optimasi dengan menguji model yang sudah dimodifikasi untuk masalah transportasi lebih dari satu produk dalam tiga kondisi. Optimasi biaya distribusi dilakukan dengan mencari pemecahan awal yang layak menggunakan metode sudut barat laut, metode biaya minimum dan metode aproksimasi Vogel yang dimodifikasi dilanjutkan dengan menentukan solusi optimum menggunakan metode batu loncatan dan metode MODI yang dimodifikasi. Berdasarkan penelitian yang dilakukan, ketiga kondisi yang diuji menggunakan model masalah transportasi yang dimodifikasi untuk lebih dari satu produk menghasilkan biaya pengiriman yang optimum./Distribution companies need to plan an efficient shipping so it does not expend large shipping costs. Therefore, companies apply transportation problem in choosing the right distribution patterns to obtain optimal distribution costs. Transportation problem applied to allocate the same product to destinations. In the problem of distributing multiple products, the transportation problem model is modified so it can be used to optimize shipping costs. Data was obtained from Sejahtera store including distribution costs data, inventory from sources and demand for each stores to optimize distribution costs using modified transportation problem model. Analysis is done by predicting the demand of products processed with time series process to assist companies in estimating the total demand of each products for the foreseeable future. Then optimizing by testing the modified transportation problem model for multiple products in three conditions. Distribution cost optimization is dones by finding feasible initial solution using modified northwest corner method, modified minimum cost method and modified Vogel approximation method followed by determining the optimum solution using modified stepping stone method and modified MODI method. Based on research conducted, all three conditions are tested using modified transportation problem model for multiple products resulting optimum shipping costs.
