Abstract
This paper presents an integrated hybrid expert system for construction planning and scheduling. The system integrates through an expert system building tool (ESBT) a relational data base, knowledge base, and its control functions; a traditional network analysis software; and interfacing programs written in FORTRAN language. This prototype system, which uses a microcomputer-based hybrid artificial intelligence environment, has some interesting features. One of its modules determines the job logic among the activities entered through an end-user interface. Another module, consisting of a set of stand-alone nested expert system submodules, modifies the unimpacted duration of activities to a realistic duration. These submodules account for variations in productivity level resulting from overtime, site congestion, reassignment of labor, learning curve, and weather conditions. An example application is presented to illustrate the essential features of the system. The system could be applied successfully in other domains, including teaching and training in construction management, analysis and preparation of construction claims, and management of contract changes.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
