Hi,

I am working on a project to do the relation between packing material and our product size which target to optimize our carton box types. I would like to seek an advise here:

Need to analyze the product size distribution which contains ‘ Width’ and ‘Length’. I am wondering which tool from Minitab I can use for doing the size distribution. As ‘Width’ and ‘Length’ have to be viewed as a whole. See if anyone encountered the same problem.

Thanks!

be notified via email.I’m not trying to be “cute” here but most physical objects that one puts in a box are 3 dimensional it would seem to me that you would want to take height into account as well.

As for analysis – you are going to have to consider all three dimensions together not separately. I’d say your first move should be a simple 3D scatter plot with X,Y, and Z corresponding the the product dimensions. You should be able to look at the plot, perhaps rotate it a bit to look at it from various perspectives and identify the combined ranges of X,Y, and Z that would accomodate various percentages of your product.

Thanks and you are right. It should be 3 dimensional normal but our product is a piece of paper or some kind of stuff like this. So, the height is depending mainly on the qty which is controllable. Still can try to use 3D scatter plot using constant value for height.

be notified via email.If it is just types of paper cuts and if quantitiy is indeed independent of type then just do a 2D scatter plot and look at the height as a separate function. It just seems odd to me that height would be independent of the other two. If we use paper as an example, you are far more likely to have a demand for greater quantities of common paper weights as opposed to heavier paper weights – while you could do a one-height-fits-all it would result in a lot of wasted shipping space (never mind carton material waste)

I will do a trial on the analysis per your suggestion to see which way is more sensible. Happy New Year!
