An Expert System Shell for Building Spatial-Decision-Support-System Development Tool

I discuss in this chapter a spatial-decision-support-system development tool (shell) which we have developed, implemented and applied to construct SDSS to assist spatial decision-making tasks (Leung et al., 1995a, b). The shell is a general SDSS development environment constructed for the purpose of building SDSS to solve specific spatial problems in an effective and efficient manner. The overall objective is to have a system which can materialize the general SDSS architecture depicted in Fig. 1.2 in Chapter 1.
