Excel Solver Product Scheduling

I am attempting to use Excel Solver to optimize the scheduling of products to reduce delays. The formulas I am using have IF and VLOOKUP functions. Based on the research I have done the solving method I should use is Evolutionary. From what I can tell once I run the solver the Lookup equations all reference the exact same cell, which is not how it is referenced before I run the solver. The only variable I am looking for the solver to modify is the order of the products.

I have attached the spreadsheet any help would be greatly appreciated.
