This important class of linear programming models has the advantage that elements of a problem can be described by a picture rather than a series of algebraic expressions as for the general linear programming model. Even if a particular problem cannot entirely be expressed as a network flow problem, very often major components of the problem can be expressed as a network. For an "almost" network model, the problem can be described using this model construct, and the worksheet or the Solver model modified to incorporate nonstandard features. Topic Menu
