Consched: Expert system for scheduling of modular construction projects

Shaked, O and Warszawski, A (1992) Consched: Expert system for scheduling of modular construction projects. Journal of Construction Engineering and Management, 118(3), pp. 488-506. ISSN 0733-9364

Abstract

The paper describes the principles, operation, and development of an expert system for progress scheduling in the construction of modular multistory buildings. Objectives of effective scheduling are presented and some rules for attaining them in this type of buildings are suggested. The scheduling in the system is task rather than component oriented. The system plans the execution of tasks in view of various managerial goals, and is very flexible in terms of building activities that it can handle and the amount of data required from the user. The system at its present stage is applicable to residential buildings with reinforced concrete skeletons. Operation of the system includes input processing of the project attributes, estimation of works quantities, generation of activities necessary for their execution, allocation of time and resources to activities, and determination of the schedule. An application example is presented. The knowledge base of the system includes a rule base, a data base, algorithms, context knowledge, and user interface. Further development will involve expansion of the technological domain, alternative managerial policies, and different compositions of floors.

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
