Résumé : |
The research carried out throughout this thesis is concerned with the conversion of linear programmes to network flow problems.
Although a network flow problem can always be expressed as a linear programme, the converse is not always true.
Many people have found that some classes of linear programmes were in fact 'hidden' network flow problems, but few have actually put forward a systematic way of testing if any linear programme can be successfully converted to a network flow problem.
The algorithm proposed in this thesis directly attempts to contruct the graph associated with the constraint matrix of the original LP programme.
If a graph can be produced, then row operations and column scaling are carried out to actually yield, if possible, the equivalent network flow model.
If a graph cannot be constructed, then the LP is not convertible to a NFP. |
