摘要

ZYX 是一家冷冻猪肉经销商。产品种类繁多,产品需求量大,导致库存短缺和订单延迟。本研究旨在使用 ABC 法根据使用量和成本水平对产品进行分类,从时间序列法中获得最佳预测方法,使用经济订货量法获得最佳订货量,并对 A 类产品的最佳订货量进行敏感性分析。A 类产品包括五种类型,即:带皮猪肚、脱皮猪肚、去骨猪腿、猪颈和猪肩。采用指数平滑法预测带皮猪肉、脱皮猪肉和猪肩肉的需求量最佳,采用线性趋势线模型法预测猪腿去骨肉和猪颈肉的需求量最佳。总库存成本的节约率为 13% 至 60%。敏感性分析的结果表明,储存的投入成本对最佳订货值的变化最为敏感。应用其中一些方法可以提供充足的原材料,避免库存短缺,从而避免订单延误,提高成本效益 关键词 :ABC分析、EOQ、灵敏度、库存、预测 XYZ公司是一家生产婴儿用品的分销商。该公司的产品种类繁多,产品库存量大,可提供长期的库存管理和成本控制。该系统采用 ABC 方法对产品的生产和销售进行分析,从时间序列方法中提取长期生产方法,从经济订货量方法中提取最优生产方法,并对 A 类产品的最优生产方法进行敏感性分析。研究人员发现,5 种 A 类产品分别是:带皮猪肚、去皮猪肚、去骨猪腿、猪颈肉和猪肩肉。指数平滑法对猪皮、猪肚皮和猪肩产品进行预测,线性趋势线模型对去骨猪腿和猪颈部产品进行预测。对 13 个样本和 60 个样本的总样本量进行持久性分析。灵敏度分析表明,输入的生物量与最优化的生物量相比是微不足道的。这种分析方法不仅能提高生物量,还能提高生物效率。相关信息 :分析 abc、eoq、敏感性、持久性媒体、 peramalan

Peramalan Permintaan Dan Pengendalian Persediaan Produk Daging Babi Beku Di PT. XYZ
ZYX is a distributor of frozen pork. Various product types, high product demand, resulting in inventory shortages and order delays. This study aims to classify products based on usage and cost levels using the ABC method, obtaining the best forecasting method from the time series method, obtaining the optimal order quantity using the Economic Order Quantity method, as well as sensitivity analysis of the optimal quantity for classified A products. five types of products are included in class A, namely: pork belly skin on, pork belly skin off, pork leg boneless, pork neck, and pork shoulder. The best demand forecasting results with exponential smoothing method for pork belly skin on, pork belly skin off, and pork shoulder products, as well as the linear trend line model method for pork leg boneless and pork neck. The percentage of savings on total inventory costs is 13 percent to 60 percent. The results of the sensitivity analysis show that the input cost of storage is the most sensitive to changes in the optimal order value. The application of some of these methods can provide sufficient raw materials and avoid shortages of inventory so that there are no delays in orders, and can improve cost efficiency Keywords : Abc analysis, eoq, sensitivity, inventory, forecasting XYZ merupakan distributor daging babi beku.
