# Network problem and solution

A network definition and solution of simulation problems

INTRODUCTION vVhile simulation was one of the first computer applications to be explored, it has been among the last to advance with improvements in software technology. Most current large simulation systems are written in FORTRAN; these simulation programs often

Network pricing problems : complexity, polyhedral study and solution approaches

Consider the problem of maximizing the revenue generated by tolls set on a subset of arcs of a transportation network , where origin-destination flows (commodi ties) are assigned to shortest paths with respect to the sum of tolls and initial costs. This thesis is concerned with a

Solution methods for multiprocessor network scheduling problems , with application to railroad operations

This thesis explores decomposable methods for a generalization of job shop scheduling which we call the Multiprocessor Network Scheduling Problem (MNSP), with a particular application to what we call the Railroad Network Scheduling Problem (RNSP). In Chapter 1

Artificial neural network methods for the solution of second order boundary value problems

We present a method for solving partial differential equations using artificial neural networks and an adaptive collocation strategy. In this procedure, a coarse grid of training points is used at the initial training stages, while more points are added at later stages based on the

network and differential evolution methodologies used in single-and multi-objective formulations for the solution of subsurface water management problems

A single-objective Differential Evolution (DE) algorithm is combined with an Artificial Neural Network (ANN) to examine different operational strategies to cover the water demand in the Northern part of Rhodes Island, Greece. Successive calls to the simulator are used to

Process network solution of extended CPM problems with alternatives

In this paper a novel method to extend the problem range of CPM problems is given. First, the CPM problem is transformed into a process network problem. It is shown how the directed bipartite process network has to be generated, and the corresponding mathematical Hardness, measured on cleavage planes of lead sulphide single crystals after reheating at 200° K. under various sulphur pressures The results show considerable scatter, but it seems justified to conclude that among
