Abstract

This paper studies a facility location with single sourcing problem which simultaneously considering opening some new facilities or closing some existing facilities. This problem comes from the inefficiency of the distribution network because of its distribution process growth. One of the mainly caused is each customer zone, which consist of several demand points, served by more than one warehouses. This policy causes high delivery cost and also makes what called marketing conflict. The objectives of this problem solving is determining number, location and distribution coverage of warehouse that could minimizing total logistic cost. Total logistic cost consist of delivery cost from warehouse to customer zone, storage and operation cost at warehouse and transportation cost from plant to warehouse. The best solution is achieved using heuristic approach and optimized using integer linear programming by examining the best configuration network offering the least total logistic cost.

Abstract

PT. Sinar Niaga Sejahtera adalah perusahaan yang bergerak di bidang distribusi. Wilayah pemasaran PT. SNS 6 Kabupaten dan Kotamadya di eks Karesidenan Surakarta. Wilayah pemasaran yang luas mengakibatkan 34 kecamatan belum terlayani oleh perusahaan dan biaya distribusi pada bulan Agustus– Juli 2009 yaitu sebesar Rp. 767.770.700,- atau 16 % dari pendapatan perusahaan (jauh diatas target biaya distribusi perusahaan yaitu dibawah 14 %). Oleh karena itu perlu dilakukan penentuan lokasi dan alokasi produk untuk gudang sub-distributor serta alokasi produk untuk outlet dengan kriteria minimasi biaya distribusi. Model yang digunakan adalah model PLANWAR yang dikembangkan oleh Pirkul dan Jayawarman (1997). Model tersebut diselesaikan dengan menggunakan software Risk Solver Platform versi 9. Hasil pengolahan data menujukkan bahwa terdapat tiga wilayah yang akan dibuka gudang subdistributor yaitu Karanganyar, Surakarta dan Boyolali. Biaya distribusi mengalami penurunan sebesar Rp. 147.353.036,- atau sebesar 20 % dari biaya distribusi sebelumnya. Pengujian kelayakan investasi juga menunjukkan bahwa gudang sub-distributor di ketiga wilayah tersebut layak untuk dibangun.

Abstract

In general, planning supply use the information from combination varying capacity and inventory to plan the aggregate rates of production by time period for groups of product. This research objective is PT. Tiga Pilar Sejahtera’s (TPS) that produces wafersticks. In the company sometimes occured the wafersticks product can be not fulfilled. This is happened because waferstick inventory unstable. This causes problems that PT. Tiga Pilar Sejahtera (TPS) was less capable to fulfill the market’s demands. To solve this PT TPS should be managing the working hours, workforces, production capacity and finished goods inventory, they are called aggregate planning. This research are determine safety stocks, planning supply and material inventory planning.Managing supply of waferstick product is started by forecast the demand. The forecast result is used to estimate safety stock of waferstick. Then the forecasting result and safety stock become of input Integer linier programming model to determine aggregate planning. The aggregate planning is used to find optomal lot size of waferstick raw material. Then lot sizing become input Planned Order Receipt in the Material Planning Requirements (MRP). Forecast method used to forecast the demand is decomposition, this method is he best method find estimation demand because it have more less MAD than the other. The determination of the safety stock is actually more accurate with the 90% by Romy & Yuli waferstick safety inventory is 1106 cartons and 2364 cartons for Pio. From aggregate planning there is back order in 13 th is 11 cartons. The planning cost for Romy & Yuli waferstick Rp 625.670.902,33 and Cost for Pio waferstick Rp 1.462.296.180,00. Waferstick material planning by optimal lot size between 695 kilograms up to 8487 kilograms by waferstick materials cost is Rp 6.315.520,00.
