Abstract

Chevron Indonesia Company merupakan salah satu industri minyak dan gas yang beroperasi di wilayah Kalimantan Timur. Kebutuhan material-material Material Repair & Operation (MRO) diatur oleh departemen Supply Chain Management. Tingginya nilai Inventory, serta nilai material yang masuk kategori slow moving masih cukup besar maka diperlukan strategi yang tepat dalam pengendalian dan pengontrolan persediaan suku cadang agar bisa efektif dan efisien. Metode yang digunakan dalam penelitian ini adalah simulasi Monte Carlo untuk menentukan nilai-nilai parameter yang terkait dengan pengelolaan persediaan suku cadang. Model dasar yang digunakan adalah model (R, s, S) yaitu model base stock dengan periodic review. Langkah awal perhitungan nilai s dan S menggunakan rumus yang mengakomodasi permintaan berdistribusi normal. Karena sifat normalitas biasanya tidak terpenuhi, maka simulasi akan digunakan untuk memperbaiki nilai-nilai awal yang diperoleh. Penentuan parameter persediaan dengan simulasi Monte Carlo dan model (R, s, S) menghasilkan suatu peramalan persediaan suku cadang di industri minyak dan gas bumi dengan biaya persediaan yang lebih rendah serta didapatkan service level yang lebih tinggi dibandingkan dengan kondisi exisiting. ======================================================================================================================== Chevron Indonesia Company is one of the oil and gas industry that doing its operation on East Kalimantan area. Material needs for Material Repair & Operation (MRO) under controlling Supply Chain Management department. The high cost of Inventory, an also high cost for slow moving materials, it needs the right strategy for controlling spare parts inventory to be effective and efficient. Monte Carlo simulation to be used in the research to determine parameter values associated with the management of spare parts inventory. The model (R, s, S) or base stock with periodic review model to be used as the basic model. Initially, calculation for s and S value using formula that accommodate the demand of normal distribution. Because of normality usually not fulfilled, then the simulation is used to improve initial values obtained. Determination of inventory parameter with Monte Carlo simulation and models (R, s, S) produces a forecasting inventory of spare parts in the oil and gas industry with lower inventory cost and obtain higher service level than the existing condition.
