Abstract

The objectives of existing computer programming methods of earthwork systems optimization in road construction have generally been either to minimize cost or maximize profit. However, the required computer memory needed is generally excessive and, moreover, the method demands a prior knowledge of the cost of transporting a unit of material along a given haul distance. As a consequence, the equipment resources would, by implication, have already been decided upon. Inexperienced personnel are clearly unable to reach this decision. This paper describes the development of an integrated system that combines earthwork allocation with the selection of equipment for road construction. Knowledge and experience possessed by planning engineers and equipment specialists has been captured and interpreted in a form suitable for manipulation by computer programs. The validity of the model is demonstrated by applying it to a real case study to provide an additional tool to management in deciding the earthwork allocation and cheapest equipment fleet cost.

Descriptive scope: 4 PCEA

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
