库存管理有哪几种方法各具有哪些优缺点

答案

参考答案:

解析:要对库存进行有效的管理和控制,首先要对存货进行分类。常用的存货分类方法有ABC 分类法和CVA 管理法。 (1)ABC 分类法又称重点管理法或ABC 分析法。它是一种从名目众多、错综复杂的客观事物或经济现象中,通过分析,找出主次,分类排队,并根据其不同情况分别加以管理的方法。利用ABC 分析法可以使企业更好地进行预测和现场控制,以及减少安全库存和库存投资。ABC 分类法也有不足之处,通常表现为C 类货物得不到应有的重视,而C 类货物往往也会导致整个装配线的停工。 (2)CVA 管理法。CVA 管理法的基本思想是把存货按照关键性分成3~5类,即:最高优先级、较高优先级、中等优先级、较低优先级,其比起ABC 分类法有着更强的目的性。在使用中要注意,人们往往倾向于制定高的优先级,结果高优先级的物资种类很多,最终哪种物资也得不到应有的重视。CVA 管理法和ABC 分类法结合使用,可以达到分清主次、抓住关键环节的目的。在对成千上万种物资进行优先级分类时,也不得不借用ABC 分类法进行归类。
