21 Optimise: (a) Shape and size (b) Shape and land value (c) Shape, size and land value Block I Block II

22 A set of solutions and the Pareto-optimal front Optimize shape and size Block I: Far from the optimum by 18.1% and 9.4%, respectively. Block II: Far from the optimum by 8.9% and 35.0%, respectively Block I Block II Optimize shape and land value Block I: Far from the optimum by 7.9% and 14.2%, respectively. Block II: Far from the optimum by 12.8% and 31.9%, respectively Block I Block II

23 Optimize shape, size and land value Block I: Far from the optimum by 13.8%, 17.6% and 11.3%, respectively. Block II: Far from the optimum by 19.3%, 35.5% and 37.8%, respectively.

26 Planning support systems take new scientific tools based on GIS, optimisation and simulation and use these to inform the process of planmaking and policy. This book is one of the first to show how this can be consistently done and it is a triumph of demonstrating how such systems can be made operational. Essential reading for planners, analysts and GI scientists. Prof. Michael Batty, Center of Advanced Spatial Analysis (CASA), University College London (UCL), UK. Springer Theses: the best of the bests PhDs 132 ( 113) since the 1960s, ambitious research activities were to observe regarding IT-support of the complex and time consuming redistribution processes within such land consolidation without any practically relevant results, until now. This scientific work is likely to close that lack... This distinguished publication is very recommendable to land consolidation planning experts, researchers and academics likewise. Prof. Dr.-Ing.
