Optimisation of cost function

Hi

I asked this questio before, but the problem has got a lot bigger so hoping for other suggestions...

I am trying to minimise the function

Cost = (units used X cost of unit) + cost of storage + cost of dispatch

cost of dispatch = max(units used)

cost of storage = variable

units used and cost of unit are fixed.

I have two stores and two dispatches. The larger the stores and dispatches, the smaller the operating cost but larger capital cost. I'm using a problem-based solver approach.

Thanks
