Input Problem Data
In order to solve a problem instance, you have to enter all needed parameters
like processing times, due dates etc..
Basic handling:
- Make shure a problem type is defined
and choose Edit|Parameters.
- In the opening window, use the View-menu to display the
desired parameter.
- Click on the item you want to edit.
- You may generate all parameters automatically using a random
number generator.
Options
Dependend on the choosen problem type you
may edit or generate some of the following parameters.
- Processing Times:
-
the time needed to carry out an operation
- Operation Set:
-
The entry in row i and column j is 1 if operation (i,j) exists, 0
otherwise.
- Machine Order:
-
A permutation of numbers 1 to m in each row 1 describes the order
in which job i is processed by the machines. For instance, if job 3
has to be processed first on machine 2 and then on maschine 5,
we write a 1 into row 3, column 2 and a 2 into row 3, column
2. After editing this matrix you have to press the button
Adopt Machine Orders.
- Due Dates:
-
a time at which the corresponding job should be completed
- Weights:
-
are used in some objective functions
- Release Times:
-
a time r_i when job i becomes ready for processing
Exceptions
- You may only edit or generate parameters which fit to the choosen
problem type .
- Machine orders are only accepted if the whole matrix is filled in
correctly.
