These problems are usually very large. Hence general purpose linear algorithms which do not exploit the special structure of the networks become inefficient. Moreover, sometimes the objective function can be non-linear. In this thesis we have discussed two types of formulation of the problem namely arc flow formulation and path flow formulation. We have discussed several algorithms for solution including optimal and heuristic methods. A problem with non-integer objective function has been discussed. Numerical examples have been included where appropriate.pdfen-NZhttps://www.wgtn.ac.nz/library/about-us/policies-and-strategies/copyright-for-the-researcharchiveNetwork analysisProgramming in mathematicsTextAll rights, except those explicitly waived, are held by the Author
