Optimisation of production based on price of energy

Hi,
can you take a look at the attachment?

My question is.
What is the optimal order to produce these products, so that ENERGY COST TOTAL is minimal?
I assume we have 120 possibilities in this case.
A,B,C,D,E
A,B,C,E,D
A,B,D,C,E
A,B,D,E,C
etc,
We don't want to split products hourly. The same products should be produced in a row.

Can anybody help me to optimise this?
Macro, visual basic code?
Any help, I don't want to optimise manually everyday ;-)

Thanks, Lauri.
