Benjaoran, V; Sooksil, N and Metham, M (2019) Effect of demand variations on steel bars cutting loss. International Journal of Construction Management, 19(2), pp. 137-148. ISSN 1562-3599
Abstract
The stock cutting process of construction steel bars causes trim loss. The demand assortment can vary considerably from job to job depending on the designs of building components and the progress of the projects. This research employs one-dimensional cutting stock problem model and conducts three sets of experiment on the variations of three parameters in order to discover the relationships between the demand variation and the cutting loss. The combination of the demanded lengths and numbers are altered to simulate many different decent jobs. Then, statistical techniques are applied to analyse the minimum cutting loss resulted from the tests. The results show that the less uniformity of the demand assortment produces more trim loss of the job. A highly unbalanced proportion of long demanded lengths also increases loss. The outcomes of this research are strategies to arrange effective cutting jobs, which will reduce the trim loss along the project timeline and consequently save the project cost.

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
