Problems with simple order-picking model

Hello. I am trying to make a simple order-picking model without process flow. The idea is that the source produces 10 types of articles (item.types) which the operator picks by the queue time. As you can see, the source has 50 arrivals which times differ from 0.01 to 0.5 seconds. I want the first arrival to be article (item.type) 1 two boxes, arrival two, article 2, 0 boxes and so on until the eleventh arrival when i want it to be article 1, zero boxes. First ten arrivals should be looked as order 1, then second ten arrivals should be order 2 and so on until the fifth order. The problem is that on the first arrival the sources produces 2 different articles, but not 1 article with quantity 2. Also, I would like to place the article 1 (item type 1) at Bay 1, article 2 (item type 2) at Bay 2 of the rack and so on.

Does anyone have an idea?

The model follows:

If you don't create an item, then don't put a row into the creation table.

If you need the type as a label, then add a label to your schedule.

If you need different item types at the same time, then add more rows of the same time to your schedule table - for each different label value a different row.

Rack: Place in Bay by case. You need to translate an article name into a number for this method.

  • you can add a number label to the items, which value is unique to the name, or
  • you put all names into an array and find the index of an article in the array.

To complete an order of an amount of 10, please look for the modulus operator "%" (int mod) and his use.

If you have further questions on my answers, then please look firstly for answers. And if you don't find any. then PLEASE create new questions, but ONLY one question per thread as it is stated in the Best Practices for using this Answers site
