Integration of Simulation with Expert Systems

Abstract

This paper investigates the integration of simulation with expert systems. Several recent engineering research projects in this field are described. Relevant research in construction is discussed and potential benefits of integrated systems are explored. Integrating simulation with expert systems can produce powerful analytical tools with immediate potential use in construction. A prototype system is developed by integrating an expert‐system shell with a popular construction simulation software. The system developed allows the user to choose suitable earth‐moving equipment (scraper versus truck, shovel versus bulldozer) under a given set of job conditions, select an appropriate simulation file, perform simulation analysis, and output cost and production rates. The expert system acts as an interface between the user and the simulation software. The user can benefit from the power of simulation analysis without having to be a simulation expert. Several issues are identified in the course of system development and described in the paper. An example is presented to demonstrate the system's application. Possible future enhancements and extensions are suggested.
