question

If your assignment is to build the model, then that would likely violate our academic policy, which you can read here:

But maybe it's not one of those cases. If your professor understands and expects you to get assistance, then it would good if you could provide a model, demonstrating the progress you have made so far, and then ask a question for guidance, in context of that model.

Dear Alina,

You have asked questions about your model several times. As a FlexSim user forum, we can answer and help in cases where you have specific questions and it is apparent that you just need some guidance to do the work yourself. However, we cannot and will not accommodate your request to bail you out of a task assigned by a lecturer.

I'm sorry to say so but if you continue, in future posts, to expect this, I will be forced to contact your lecturer, Dr. Yana Chibiryak, on this matter.

All the best!
