Assigning all task in an order to same resource

Hi,

I am trying to figure out how I can assign tasks from same order to the same resource. i.e. I do not want the tasks to be split among different resources. Since process time is stochastic, I do not want to simply assign task to equipment upfront.

Test model without this constraint -Task_Assignment_test.fsm

For example if I have 6 orders and 15 parts to manufacture, one of the feasible assignment is as follows

Software Version:

FlexSim 22.2.4

I would create a token for each order and have the resources pull them from a list, then pull the tasks for each order.

Example changes attached.

Thank you Jason! One thing I over simplified in my initial ask is that the tasks could come at different times, For example, Resource 1 could have processed Order 1 task and moved to Order 2 task, when another Order 1 task would be generated and that would need to be assigned to Resource 1 again next time it is idle before assigning new Orders. I am thinking I would have to create a lookup for this case? Any advice on maintaining this lookup in the model. Simplest I can think of is a global table or may be another list of orders partitioned by Resource_ID
