Using Solver with Linear Constraint(s)
Excel 2002 SP3
Win XP Pro SP2 *Follow-up to: microsoft.public.excel* Hi, Sorry but I have "writer's block" right now as regards to a spreadsheet solution I need. It's a simple problem but I am just drawing a blank at the moment.... Let me try to describe it: I have a cell chosen as the target for solver e.g. M25 = 1% (total market share) And a range as the cells to change by solver e.g. J4:J23 (market share as % at each period e.g. month or quarter, etc.) Each cell needs to progressively grow until reaching 1%. And the rate of growth of the cells in J4:23 needs to stay constant or linear. The 1st value affected by J4 is a $ amount like $100,000. The ending value is very high in comparison: 100,000 % that the original $ value. I cannot project the 1% divided by the number of period as the 1st period growth would be much too high. I need the values in the range J4:J23 to change to solve the equation but in a linear fashion, each cell value being progressively higher than the last. I have played around with the Linear, Automatic Scaling, etc.; options but have not been able to get the result I want. Actually, I do not really see a linear solution in this case but again, I am in a "blank" right now.... Any help or suggestion? |
