Attention is focused on nonlinear modelling in space and time, with particular emphasis on migration behaviour. A pedagogic overview is provided of the use of dynamic models for migration behaviour based on synergetic dynamic effects. This is followed by an attempt at identifying bifurcation...

A range of microcomputer applications packages developed in Australia of relevance to urban infrastructure planning and management are outlined. The array of packages range from those concerned with the acquisition and analysis of data typically assembled for strategic planning studies...

The energy and environmental implications of traffic movements through road networks at the local level (that is, 'dense' road networks) are considered. This level is becoming of critical importance in traffic planning, particularly for regional and local government agencies. The development and...

The irregularity of land uses and land parcels which constitute the morphology of a small English town is measured. Form is described by the digitised perimeters and areas of land-use parcels, and various methods are introduced which relate area to perimeter, and perimeter to scale, enabling the...

The concepts of multiple, excess, backup, and expected coverage are defined. Model formulations using these constructs are reviewed and contrasted to illustrate the relationships between them. Several new formulations are presented as is a new derivation of the expected covering model which...

The historical development of microcomputer use in US planning is reviewed and the major ways in which microcomputers are currently being used in planning practice and education are evaluated. Seven applications of microcomputer technology in planning are examined: electronic spreadsheets,...

The findings of a survey of British planning schools carried out during spring 1986 suggest that the number of microcomputers available in British planning schools has increased by at least two-and-a-half times over an eighteen-month period. However, compulsory courses on computer applications...

A recently proposed approach to the problem of identifying critical resource allocations requires that a unique central point be found within the feasible region defined by a set of linear inequalities. Although two procedures for identifying such a point have been proposed, each has significant...

Multicriteria evaluation is discussed in this paper. The importance to such methods of establishing weights is stressed and it is argued that the 'weighting problem' is their Achilles heel. Moreover, this problem is not escaped by adopting a 'conditional approach' to the results of such methods....

The recent proliferation of facility-siting conflicts underscores the need for new analytical techniques in which the external effects associated with noxious facilities are considered explicitly. In general, in prescriptive facility-location models it is assumed that having populations...
