Hi everyone,

For a student project I need to analyse a certain inventory system, but unfortunately I have not been able to implement it in Flexsim. The basic idea is that a product (demand = 300 units per period) is ordered in batches of size 1266 units once its inventory level goes below 1280 units. Upon release, the lots goe immediately into setup (0,5 periods) and production (400 units per period) if the process is idle. If the process is busy, jobs wait in queue under the first-come first served discipline. To me it seemed a very easy undertaking, but after a few days of trying and an approaching deadline I am feeling kind of desparate now.

The general structure and the model are attached below. I really hope someone is willing to help me out as this is my last resort. If implementing this model takes a lot of time, I am more than willing to compensate for it.

If more information is needed, I'd be more than happy to provide it.

Thank you for taking the time to read my question

Kind regards

Ludovic
