Model modeling issues

I want to implement an article about the content mentioned in the literature.

The content is as follows

At simulation time 12, workpiece 3 is processed on machine B. Since both workpiece 4 and workpiece 1 need to go to machine B for processing, the timing of work dispatch decision will be faced at this time. According to the status information, workpiece 4 is currently blocked on machine C, and workpiece 2 must go to machine C for processing. Therefore, selecting workpiece 4 can unblock machine C, allowing workpiece 2 to continue processing. However, if workpiece 2 is selected 1, then workpiece 3 will be blocked because workpiece 4 is still blocked on machine C and cannot leave the machine, resulting in the inability to continue processing. Therefore, this study selects workpiece 4 as the action for dispatching decisions.

Finally I have another problem, I want to calculate the slack time.

But I don’t know how to complete the following description in flexsim

The processing of workpiece 4 is completed at simulation time 8, and the status of the job attribute is updated to processing completed. Since workpiece 4 is blocked on machine C, the status of machine C and workpiece 4 is updated to be blocked. Allowance and remaining time. Refer to the workpiece information to know that workpiece 1, workpiece 2 and workpiece 3 will be delivered late. The allowance time can be obtained by subtracting the current time from the delivery date and subtracting the remaining processing time. The allowance time is 3, 4 and 3 minutes respectively. , the remaining time is the distance between the delivery date and the current time. After calculation, the remaining time for workpieces 1 to 4 is 2, 6, 8, and 3 minutes respectively.allcombos-22-0-1-fm.fsm

Hi @mark zhen ,

It looks like this question may be part of a homework assignment or academic project. The professors who assign simulation modeling exercises using FlexSim expect that the academic integrity of their assignments will be maintained. In addition, we are supportive of Honor Codes or Pledges that regulate the behavior surrounding academic assignments.

I recommend reading our best practices page on the subject, which includes some resources that you should find helpful as you use FlexSim for academic purposes. I also highly recommend Dr. Allen Greenwood's FlexSim Primer, which was written specifically for students and professors.

Hello, I want to experiment with the following content while reading the literature, but it does not belong to the homework or anything you mentioned, because it mentions reinforcement learning and I want to practice it.

I'd repost your model with the names of the processor and items match those in your description.
