做过实际成本的同仁都知道,在实际成本计算中,最难取得的数据是投产量。
有人会通过月末假退料的模式,使本期投产量=本期入库量,但工作量先不说,数据可能更乱。
如生产任务单是1000套,本月领料800套,本月入库600套,那在制品应该是多少呢?
可能有人会说是400套,但正确的答案是200套,答案计算起来似乎很简单800-600=200
然而事实并没有这么简单,800从哪里来?生产部填写?
更让人头大的是,领料会刚好按套数领吗?
在此背景下,结合会计中的约当系数法,故提出约当投产量法的概念,给各位小伙伴分享一下:
计算公式:任务单本期约当投入产量=(领料数量*单价-以前期间领料数量*单价/(投料单数量*单价)
注:一旦任务单结案,则任务单投入产量=入库产量(没考虑废品入库)
领料是否配套,都能计算出一个投产量,如果完全配套,属于理想状态,与实际一致。
该方法适合场景:生产周期不能太长或价格不能剧烈波动,满足其一即可,否则期间较长且价格剧烈波动,可能会导致最后期间的投产量为负数。
代码是4年前写的,分享给大家,比较粗糙,见笑了:
