Use 1 Source to create 2 types of boxes, and grab statistics separately?

[ FlexSim 20.2.3 ]

Hi,

I would like to create Boxes and change their attribute. Following are my 2 examples:

1. Create 5 units Box A, item.Type = 1

Create 5 units Box B, item.Type = 2

2. Create 10 units Boxes, then I want 50% of them to be Box C, 50% Box D.

First question is: My setting in Source3 is: Set Label by Percentage > 50% value = 3 ; 50% value = 4.

I suppose Box C & D should then different in color, but they aren't.

Second question is: How can I grab the throughput of Box C and Box D separately? or I can only grab input of Sink3(sum of Box C + Box D)?

I tried to look for item.Type in Dashboard > Table > Options, but there only existSource.fsms Sources, Processors, Queues, Sinks.

Third question is what content means in FlexSim. Does it equal to WIP? As I can't find WIP in statistics.

Thank you!

Hello @Tzu Hsuan C,

I will try to answer your questions:

1. You need to add a new trigger using the label of the item (Set Color By Case for example). You only add a label now, but not color (except A).

2. You should use Output By Type dashboard.

I hope I have been helpful.

But I wonder in the case 50% value 3, 50% value 4,

why is the output still unbalance in throughput?

You have to differ between ratio and statistical distribution. You use a statistical distribution, then there is a deviation. There are systematical or random approaches to keep a ratio constant on a long run.

Examples are here

Hi, Jörg Vogel

May I ask how to keep a ratio constant?

When “Type” value

current.stats.output.value%2+1

is 1, the Object would be red. What about “Type” value = 2?

I don't quite understand how to create 2 types of item by not using by Percentage.

Thank you!

You can add a row and labels to your "arrival schedule" on the source. Something like this:

The thing to note here is that all the Type1 items will be created before the Type2 items. Another option is to use the process flow "Date Time Source." It's similar to the other arrival schedule source except for you can make the boxes randomly spaced in the time frame given in the first and second columns.

You then use a "create object" activity to put the objects in the queue.
