A Discussion and Description of the General Equilibrium Model (GEM),
Abstract
The general problem to be solved in navigation modelling can be summarized as follows: For all waterway movements select those which reflect the best utilization of the system (i.e. maximize benefits) given that any individual movement has associated benefits in the form of reduced transportation costs and associated costs in the form of lock delays. GEM uses pricing convention that accurately describes the marginal contribution of each movement to system benefits, by ensuring that each solution of the iterative process is feasible. GEM finds those combinations of prospective movements that satisfy the constraints (locks) of the general problem and then searches through these alternative feasible solutions to obtain the optimal solution that maximizes benefits.
