Abstract
Production, Exchange and Consumption Allocation System (PECAS) is a generalization of the spatial input-output modelling approach used in earlier land use transport modelling systems. PECAS has two component modules. One is the space development module that represents the actions of developers in the provision of space, land and floor space, where activities can locate, including the new development, demolition and re-development. The other is the activity allocation module, which represents how activities locate within the space provided by developers and how these activities interact with each other at a given point in time.
