这是里的的一个公式,计算某日能做多少产品,由于公式太长,我基础太浅,此公式的计算过程,还有INDIRECT在此公式中的作用.

附上图片,在右下角的这个800的位置输入的此公式 

EXCEL ｛=IF(OR($A9=0,$E9=0,S=0,$N9>S$7,$K9=SUM($R9:R9)),IF(L=1,MIN($K9-SUM($R9:R9),$M9,$J9*SS),IF(SUM(S8:INDIRECT(T&(M+ROW($A$8)))/$J8:INDIRECT("J"&(M+ROW($A$8))))*1/SS>=1,MIN((1-SUM(S8:INDIRECT(T&(M+ROW($A$8)))/$J8:INDIRECT("J"&(M+ROW($A$8))))*1/SS
第一步判断$A9=0,$E9=0,S=0,$N9>S$7,$K9=SUM($R9:R9）这些条件是否有成立的,有成立的就显示为空,都不成立时就到
第二步L=1 成立时执行MIN($K9-SUM($R9:R9) 不成立$M9,$J9*SS
第三步SUM(S8:
(T&(M+ROW($A$8)))/$J8:INDIRECT("J"&(M+ROW($A$8))))*1/SS>=1这个是否成立,成立时为空不成立就执行MIN((1-SUM(S8:INDIRECT(T&(M+ROW($A$8)))/$J8:INDIRECT("J"&(M+ROW($A$8))))*1/SS)*$J9*SS)*$J9*SS,$K9-SUM($R9:R9),$M9,$J9*SS
注释：
IF 条件判断函数
sum 指定区域内的数字求合
min 指定区域内的数字最小值
NDIRECT 此函数立即对引用进行计算,并显示其内容
ROW 返回引用的行号
