File to upload |
(Optional) |
Uploaded file '.xlsx', such as
faciloc.xlsx. |
Sheet name |
(case sensitive) |
Excel sheet (if uploaded file; otherwise ignored). |
'csv' data |
|
Screen data (in 'csv' format, Am or Eu),
ignored (but necessary) if a file is uploaded

Initial guesses for the solutions (X, Y). • |

From file (uploaded '.xlsx'
or inserted '.csv'), computes the (Euclidean) coordinates
of the optimal facility location, source, given the coordinates
of the destinations. (The sheet named pentagon is
in the suggested uploadable Excel file.)
For initial (both) guesses of 0, the centroid
will be used.
The uploaded Excel file (xls[x]) can be
"European" or "American", as these are identical
(not so for 'csv').
The default data lead to a run time of ~2 s.
This web page computes the total cost. In another page
of ours a relative cost is computed
(× 100 ⁄ ∑ Q).

in the data.) |
