Hello!
I'm a new Access user and I believe I'm facing a problem that can be
solved easily, but I don't know how.
My goal is to calculate monthly failure rates A failure rate is the
result of dividing used parts by the number of systems. For example.
There is a set of used parts {a,b,c,d,e} and a set of systems
{g,h,i,j,k}. These sets are monthly updated. Now I would like to get
time-series for different failure rates calculated by for example
{a,b}/{g,h,i} and {c,d,e}/{h,j,k}. The number of used parts varies
every month and the number of systems will increase every month, this
has to be taken into calculation.
Can somebody please help me. If my problem is not clear enough, I can
explain it in more detail.
Thanks in advance!
