Is this a candidate for Oracle MRP or is this overkill?

I'm an Inventory/Purchasing guy and have been asked to research the MRP module as a possible solution for a pending systems conversion for a new acquisition.

This facility does custom refurbishments so there is no repetative purchasing of major items. eg Project "ABC" requires part numbers "123", "234" and "345". There is a good chance they would never order any of these 3 items again for future work. Project "XYZ" requires part numbers "456", "567" and "678", and again - these would be one-off purchases.

Basic hardware is used across all projects and could be planned/managed using MinMax, ROP, etc.

Here's the question - is MRP the way to go for one-time purchasing? It seems like a lot of work for situations when you're going to buy an item just once. (maybe twice but 10 years from now when another customer requirement happens to call for the same item)
