Model production process to bypass an immediate operation in sequence & proceed to the subsequentone

Summary:

We have requirement to model production process where decision to bypass an immediate operation in sequence and to proceed to the the next subsequent taken depending upon whether the resource is busy or available but the skipped operation can be revisited later when the resource becomes available.

For example; I have 10, 20, 30 operations. I can skip operation 20 and proceed to 30 if the resource at 20 is busy & can be completed later when the resource becomes available.

Inputs much appreciated.
