Some simple land-use-allocation problems are constructed and used to illustrate geometrically the crucial role played by the generalised upper bounding structure in the linear programming formulation of such problems. As a direct result, this leads to an elaboration of the LUPLAN simplification...

In this paper, aspects of four areas of controversy which have recently surrounded the development and application of <I>Q</I>-analysis are examined. It is suggested that the difficulties over which the controversy has been generated are underpinned by important substantive problems, which those...</i>

In this paper the author reflects on his experience as both theorist and practitioner in Canadian planning. The lack of any rigorous theoretical underpinning for planning practice is identified. Three reasons for this are advanced: the inhibiting effect of daily practice, the lack of any real...

A decision framework is presented for a class of multicriteria decisionmaking (MCDM) problems, arising in the context of urban transportation planning, where the set of options is finite, impacts are uncertain, and risk attitudes and value trade-offs cannot be established or assessed a priori....

The author introduces a decision method for facilitating physical planning and other decision processes at central government level, at the same time, taking into account some justified differences in local needs for the provision of urban facilities. The method considers the following factors...

A formal model for defining transformations of languages of designs in terms of the grammars which generate them is described in detail. First, a <I>normal form</I> for grammars is presented which distinguishes two basic determinants of the compositional structure of designs in a language: spatial...</i>

Since 1950, planning theory and practice have been affected by a series of intellectual revolutions, affecting especially the Anglo-American world. In the 1950s and 1960s, the traditional blueprint or master plan approach was largely supplanted by the systems approach, but this, like its...

In this paper the author identifies a widening gulf between theory and practice in planning during the last decade, in Britain at least. The reasons for, and implications of, this gulf are discussed. The author begins by attempting to 'identify' planning and to clarify the meanings of 'theory'...

Two circuit-based measures of relative spatial accessibility are derived from a synthesis of the spatial interaction and graph-theoretic approaches to measuring locational benefit. They offer a much better description of the locational accessibility pattern of urban truck terminals in Chicago...
