A PLANNERS INTRODUCTION TO EXPERT SYSTEMS

Expert systems are computer programs that apply artificial intelligence programming techniques to problems that involve narrow, clearly defined subject areas. They differ from conventional programs in that facts and rules are separate from a program's underlying control structure and a program's reasoning can be explained easily to the user. Although operational systems to aid planners have not yet been completed, prototype systems have been built in areas such as site planning and park management. The potential value of expert systems to planners is great, and thus planners should follow developments in this rapidly changing field.
