A multi-attribute decision-making module for the evaluation of alternative land consolidation plans

Abstract

This paper explains the 'Evaluation module' of a computerised land consolidation planning support system. It is a multi-attribute decision-making approach that evaluates alternative land redistribution solutions generated by a Design module. The method introduces the idea of a 'parcel concentration coefficient' for measuring the dispersion of holdings and a 'landowner satisfaction rate' for estimating the acceptance of the new land redistribution plan by the landowners involved. The paper explains how the evaluation criteria have been selected, weighted, standardised and used for ranking the alternative solutions. Non-linear value functions for each evaluation criterion are introduced through the involvement of five land consolidation experts. A sensitivity analysis is reported and a case study application of the whole 'Evaluation module' is presented together with screenshots of the user interface.
