An expert system applied to earthmoving operations and equipment selection

Alkass, S T (1988) An expert system applied to earthmoving operations and equipment selection. PhD thesis, Loughborough University, UK.

Abstract

The thesis represents an effort to assess the current and future development of expert systems relating to civil engineering problems. It describes the development and evaluation of an Expert System (ESEMPS) that is capable of advising on earth allocation and plant selection for road construction similar to that of an expert in the domain. Knowledge for this particular domain was acquired from field practitioners such as planning engineers and equipment specialists. The development of the appropriate knowledge acquisition techniques are covered in details together with evidence provided on suitable methods for interpreting the information gathered into a form capable of being manipulated by computer programme. The system was tested both with practitioners and novices and the concept of the a consultation validated. It was also tested against a real data from a road construction project under construction. During the evaluation of ESEMPS on site It's decisions were considered acceptable to the practitioners who reviewed them. The system has significant potential for making an immediate contribution to inexperienced engineers as well as to the practitioners in the field of the road construction. While not all the decisions were equal to those of experts. this should be expected because no two experts will usually arrive at the same decision at the same way. ESEMPS will have a significant benefit if used in developing countries where experts are rare and very expensive to employ.

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
