Period factor doesn’t work for SNP Optimizer

Hi Expert

We have a supply chain of move material X from Plant A to Plant B via movement STR/STO.

 

We use SNP Optimizer to create STR.

 

The SNP book is in Monthly bucket, we have demand (FA) released to SNP book at the Middle of Monthly bucket (e.g. Jan 16, 2015).

Our expectation is that SNP Optimizer run, and create STR in the middle of the bucket as well.   However the STR is created in the beginning of the bucket. (e.g. Jan 1st, 2015)

 

We set Period factor to 0.5 in MAT/LOC and TL , and it looks Period factor doesn’t work with SNP Optimizer.

I tried the Bucket Offset with1, 00 and 0.5, it also doesn’t change STR result.

Could anyone help on this , we want SNP Optimizer to create the STR in the middle of the bucket.

Thx James

OK, let me give an example-

Say you are running optimizer in weekly bucket (7 days in a week) and planning start day as beginning of this year, till next 6 months.

So your bucket definition would be like 1-4th Jan, 5-11, 12-18, 19-25 .... like that

Now say in DC1 you have a demand for 100 units of product A on 15th Jan and this DC1 can source from Plant1.

Here the exact availability date to meet the demand is 15th Jan. This length is 4 days from the start of the bucket and the length of the bucket is 7 days. SO the exact availability date for optimizer will be 4/7= 0.57 of the total  bucket length.

Now if you have a bucket-offset of, say 0.80, then the rounding limit would be 0.8 * 7= 0.56 which is less than the  limit (0.57) for this demand. So the exact availability date falls after the rounding limit, hence the product will be available at the start of the next bucket (at bucket= 19-25) here.

Now if you have bucket-offset of, say 0.90 or bigger number, then the rounding limit would be 0.9 * 7= 0.63 which is greater than (0.57) for this demand. So the exact availability date falls before the rounding limit,  hence the product will be available at the start of this bucket (bucket 12-18).

Hope this helps.

Thanks,

Satyajit
