I have a problem where I have 2 different types of raw-material. These materials can be processed in two different production-lines which take different amount of time, depending on raw material. After the production lines, I have a worker that needs around 5 minutes to pack the finished product. He can only process one finished product at a time, and there is no place for a queue. I'm looking for a model that can decide at which times I need to put the raw material into the process-line to that the worker gets a finished product every 5 minutes.
I'm looking for a finished or similar optimization models. Does anyone recognize this problem and can supply me with an model, or can you maybe recommend me some papers.
Thank you!
