目前,一些大中型企业在备件储备方面普遍存在储备与需求之间不平衡、储备周期过长、备件利用率低等问题。为此,根据备件使用规律及有关数理统计原理,提出确定备件最佳储备量的方法。以C620-1车床为例,该车床共有200多种零件,列入备件的有120种,其中大修需用的30种,日常维修所用为90种。按不少于一个大修周期的统计数据计,更换频数最多的为11次,最少的0次,更换频次高的 At present, some large and medium-sized enterprises generally face the problems of reserve and demand imbalance, long reserve period and low utilization rate of spare parts in the spare parts reserve. To this end, according to the law of use of spare parts and mathematical statistics, put forward to determine the best spare parts reserve method. To C620-1 lathe, for example, the lathe a total of more than 200 kinds of parts, including 120 kinds of spare parts, including the need for overhaul of 30 species, 90 kinds used for routine maintenance. According to the statistical data of not less than one overhaul period, the frequency of replacement is 11 times, the least 0 times, the replacement frequency is high
