摘要

The paper presents a population synthesiser based on the method of Iterative Proportional Fitting (IPF) algorithm developed for the new Danish national transport model system. The synthesiser is designed for large population matrices and allows target variables to be rep resented in several target constraints. As a result, constraints for the IPF are cross-linked, which makes it difficult to ensure consistency of targets in a forecast perspective. The paper proposes a new solution strategy to ensure internal consistency of the population targets in order to guarantee proper convergence of the IPF algorithm. The solution strategy consists in establishing a harmonisation process for the population targets, which com bined with a linear programming approach, is applied to generate a consistent target rep resentation. The model approach is implemented and tested on Danish administrative register data. A test on historical census data shows that a 2006 population could be pre dicted by a 1994 population with an overall percentage deviation of 5-6% given that tar gets were known. It is also indicated that the deviation is approximately a linear function of the length of the forecast period.
