Abstract

Based on damage data owned by PT XYZ, the compressor engine that has a history of high damage is the D32 CP8 Compressor Engine. Critical components of the D32 CP 8 Compressor are determined using a risk matrix. The critical components selected from the D32 CP8 Compressor Engine are Screw Motor, Refrigerant Air Cooler, and Cylinder Bearing Oil Cooler. This study uses the Reliability Centered Spares (RCS), Min-Max Stock, and Reorder Point (ROP) methods. The data collection and processing results obtained the need for critical components in the next 1 year based on the MTTF critical component data. These calculations show that the value of the required spare parts for the Motor Screw, Refrigerant Air Conditioner, and Cylinder Bearing Oil Cooler in a year is 8 components. The minimum Stock of the Screw Motor is 3 components, the maximum stock is 8 components, ReOrder Point point is 4 components. The minimum stock of 4 component air coolers, maximum stock of 7 components, ReOrder Point when 3 components. The minimum stock of a Cylindrical Bearing Oil Cooler is 2 components, the maximum stock is 6 components, and the ReOrder Point is when there are 2 components.

D32CP8压缩机备件需求估算与库存策略的设计
根据PT XYZ拥有的损坏数据,历史上损坏严重的压缩机发动机为D32 CP8压缩机发动机。D32 cp8压缩机的关键部件使用风险矩阵确定。D32 CP8压缩机发动机选用的关键部件为螺杆电机、冷媒冷却器和气缸轴承油冷却器。本研究采用以可靠性为中心的备件(RCS)、最小最大库存(Min-Max Stock)和再订货点(ROP)方法。数据采集和处理结果根据MTTF关键部件数据得出未来1年的关键部件需求。由此计算可知,电机螺杆、制冷剂空调、气缸轴承油冷却器一年所需备件为8个。螺杆电机最小库存为3个组件,最大库存为8个组件,ReOrder Point点为4个组件。空气冷却器最小库存为4个组件,最大库存为7个组件,再订购点为3个组件。圆柱轴承油冷却器的最小库存为2个组件,最大库存为6个组件,重新订购点是当有2个组件时。
