Modelling of optimisation problems for diakoptical solution

Engineering or economic problems can be modelled by equivalent electrical networks and conveniently solved by modern advanced techniques. This paper describes a particular electrical model made of impedances, transformers, and current and voltage sources, used to represent the general economic problem which could be solved by the powerful technique of diakoptics shown in a companion paper. The modelling technique is applied to a gas-dispatch problem and shows, by example, the analogy of orthogonal transformation with linear programming.
