摘要
本质——预测和控制来自PT . XYZ shusi东南部的calcium carbide和flour spar原料的供应，其独特目的是预测和确定最优和有效的原料供应，从而减少库存过剩和库存短缺。根据计算结果，如果面膜在钙钙原料供应中使用单次平滑性的方法，将会得到一个更大的斜坡使用图表，并且会随着时间的推移而增加，而spar原料的成分会获得比实际和变量使用更倾斜的使用图表，而且会减少。钙卡宾枪安全供应数量高达184289单位一天和面粉spar 13462万单位/天,或预订点限制原材料相关的公司所需要的钙碳化物192318万单位/天spar 13951万单位/天,面粉和硬质合金原料采购钙和面粉spar最佳频率是购买原材料中的十二倍的一个时期。摘要及控制来自苏拉威西省XYZ东南苏拉威西省的calcium和絮料供应，具有特殊的目的，以确定最优、最有效的原料供应，以便减少过度供应和供应不足。改编自the results of calculations,如果用境单身exponential锤方法预测procurement of raw钙碳化物材料将获得更多坡道usage graph和tend to rise超时,而《raw面粉spar材料获得更多sloping usage graph比实际利用可变和tend to decrease。钙卡宾枪安全inventory of 184289之数量单位/ day to和面粉spar amounted 13462单位限额或point》day, raw ordering材料需要由公司为钙卡宾枪amounted to 192318单位- day and面粉spar amounted to 13951单位- day, and raw钙碳化物材料和最佳的购买频率spar面粉是十二raw时报之购买材料在一号期。
Analysis of Forecasting and Control of Calcium Carbide and Flour Spar Inventories (Case Study: PT. XYZ Southeast Sulawesi)
Intisari— meramalkan dan mengendalikan pasokan bahan baku calcium carbide dan flour spar di PT XYZ Sulawesi Tenggara, memiliki tujuan khusus untuk memprediksi dan menentukan pasokan bahan baku yang optimal dan efisien sehingga dapat meminimalisir terjadinya kelebihan stok dan kurangnya stok. Berdasarkan hasil perhitungan, jika peramalan menggunakan metode single exponential smoothing dalam pengadaan bahan baku kalsium karbida akan diperoleh grafik penggunaan RAMP yang lebih banyak dan cenderung naik dari waktu ke waktu, sedangkan bahan baku tepung spar memperoleh grafik penggunaan yang lebih miring daripada penggunaan aktual dan variabel dan cenderung menurun. Jumlah persediaan calcium carbide safety sebesar 184.289 unit/hari dan tepung spar sebesar 13.462 unit/hari, batas atau titik pemesanan bahan baku yang dibutuhkan oleh perusahaan untuk kalsium karbida sebesar 192.318 unit/hari dan tepung spar sebesar 13.951 unit/hari, dan frekuensi pembelian bahan baku kalsium karbida dan tepung spar optimal adalah dua belas kali lipat dari pembelian bahan baku dalam satu periode.
Abstract— Forecasting and controlling the supply of calcium carbide and flour spar raw materials at PT XYZ Southeast Sulawesi, has a special purpose to predict and determine the optimal and efficient supply of raw materials so as to minimize the occurrence of excess stock and lack of stock. Based on the results of calculations, if forecasting using the single exponential smoothing method in the procurement of calcium carbide raw materials will be obtained more RAMP usage graph and tend to rise over time, while the raw material flour spar obtained more sloping usage graph than actual use and variable and tend to decrease. The amount of calcium carbide safety inventory of 184.289 units/day and flour spar amounted to 13.462 units/day, the limit or point of ordering raw materials needed by the company for calcium carbide amounted to 192.318 units/day and flour spar amounted to 13.951 units/day, and the frequency purchase of calcium carbide raw materials and optimal spar flour is twelve times the purchase of raw materials in one period.
