I would like to know how to adjust this model of mine.

spt (1).fsmThen the process sequence of my model is as follows: type 123 is blue, white, and yellow, respectively.

Then I want to use this model to complete the dispatching rule of spt

But because I am a part-timer, my idea is to calculate my processing time on a rolling basis. For example, when I have these three products in q4 (waiting in the wip area), I need to calculate the remaining three. How much processing time? White may be the first stop so she has 30 seconds to process, yellow only has this processing so she has 10 seconds, and blue is 20 seconds. According to spt law, I may give priority to yellow Goods, specific ideas as above, how can I tune my model.

Create a list with the items to process. Pull the one with the least processing time.

I don't understand what you mean when should I push the item to the list and give it time. Can you give me an example using my model?

Use a field called 'ptime' in the list and enter 'Order by ptime asc' in the pull.

The field could be a label reference on the item or an expression that looks up the time using the part type and the puller.
