ABSTRACT

In this chapter the preliminary urban model is developed further. In particular, industry is divided into two different sectors: a heavy exporting sector as before, and also a local industry which served both local residents and also the heavy industry. The model is not really different in nature from the earlier version, but it is now inspired by data coming from Brussels, and so comes much closer to really describing reality. The characteristic feature of human systems is of course that of the complex interaction of human actors with their environment and with each other. An important point of our approach is that we attempt to represent the decision process of the interacting actors, taking into account

their limited perceptions, and particular value systems of each type. To do this we construct the ‘value space’ for each type of actor from the various dimensions which they can discern of the attributes of the various choices. The dimensions retained by various types of actor are of course ‘role dependent’, and are the result of how they have been led to believe people in their positions should act.
