Decide activity based on array value

I need some help in sending tokens to a connection based on if the array contains a certain value.


In the attached model, I have a schedule source for token. They then go through a subflow acquiring the resources they need. Some tokens may only have one resource, some have 2. After acquiring resources, they then go through a decide activity (Decide Array in the model). The decide activity is to find out if the tokens have the resource "x2." If they have the resource, then they have to go through a delay before continuing on. I am having trouble using the "If Array Contains Value" on the decide activity.


Any help would be appreciated. Thanks.

Hi @dcorral,

It's hard to know how to help without looking at your model. To receive a more accurate solution, please post your model or a sample model that demonstrates your question.

If your model contains sensitive information, you could first toggle your post as private using the "make private" option under your question's "gear" menu. Private questions are visible only to site moderators. You can also contact your local FlexSim distributor for phone or email help.

The values in the "resource" array will be pointers to the acquired objects. You need a pointer to the "x2" object, for example as a label on the token, to be able to compare the array values to it.

To check whether any of the acquired resources if part of the "x2" group you can use the following code. The structure is the same as the default "Value In Array" option, just the check in the if-condition is different.

Array array = token.resource?;
Group x2 = Group("x2");

for(int i = 1; i <= array.length; i++)
{
    if(x2.indexOf(array[i]) > 0)
        return 1;    
}
return 2;

You also need to check if the token actually acquired something before sending it to the Release activity.
