ABSTRACT
In this chapter, we look at the problem of modelling changes in the patterns of employment and residence at the scale below that of the previous chapters-that of within cities and towns. We also begin to discuss the issue of modelling more explicitly the decision making process of the individuals within a system. Instead of simply adopting an ‘ecological’ description such as that of Chapters 2 to 4, with a ‘crowding’ term acting on a population within a zone, we develop an ‘intra-urban’ version of the actors decision making models used in the model of Belgium. Again, in the terms laid out in Chapter 1 the models concern self-organization rather than evolution because the model generates the changing spatial patterns of employment and residents of different kinds, but the classification itself does not change over time. The model generates changing spatial structure, but not changing structures of variables, nor the possibility that actors involved may change their goals and preferences.
