Using ACCPM in a simplicial decomposition algorithm for the traffic assignment problem

Categories Complementarity and Variational Inequalities, Transportation Tags , , ,

The purpose of the traffic assignment problem is to obtain a traffic flow pattern given a set of origin-destination travel demands and flow dependent link performance functions of a road network. In the general case, the traffic assignment problem can be formulated as a variational inequality, and several algorithms have been devised for its efficient … Read more

A nonlinear optimization package for long-term hydrothermal coordination

Categories Applications - Science and Engineering

Long-term hydrothermal coordination is one of the main problems to be solved by an electric utility. Its solution provides the optimal allocation of hydraulic, thermal and nuclear resources at the different intervals of the planning horizon. The purpose of the paper is twofold. Firstly, it presents a new package for solving the hydrothermal coordination problem. … Read more
