I am building a DES model of a port and I have a sieze block for resourcePool (forklifts and manpower) when trucks come, a forklift and man are seized and it is connected to a delay block. I am trying to show that if the queue of trucks reaches a threshold, lets say 10 trucks then it will trigger more resources (forklifts) to reduce the queue then go back to its original state of 3 trucks for example.

any help would be appreciated!

The way you are describing you want to check for some condition and dynamically adjust the capacity. On the ResourcePool documentation you can see the following description:

The capacity of this block (the number of units) can be defined directly as a number that you type into its Capacity parameter. Then, if you want to change the number of resources dynamically at the model runtime, you can use the set_capacity(new value) function.

So one way to do that would be to check when an agent enters the Service or Seize block and adjust capacity accordingly, similar to the following example:

With this code on the Service block:
