A conceptual case-based decision model for mitigating construction delays
Ng, S. Thomas, Deng, Michael Z.M., Lam, Ka Chi, & Skitmore, Martin (2000) A conceptual case-based decision model for mitigating construction delays. International Journal of Construction Information Technology, 8(2), pp. 1-20.
A common method of recovering a delayed construction programme is by schedule compression through activity crashing. To be of practical benefit, however, the cost-effectiveness of crashing any of the remaining construction activities needs be examined before a decision is reached. Although the likely cost and productivity effects of crashing can be calculated using standard estimating techniques, the actual time-cost relationship may be affected by a number of external factors, and the experience and judgement of planners is needed to take this into account in selecting activities to crash. Case-based reasoning (CBR) is regarded as a suitable decision approach for capturing and reusing experience of this kind and the aim of this paper is to examine whether CBR could be applied to modelling the delay mitigation (DM) domain. The process of DM is first examined. A conceptual framework and rapid prototype is then developed based on the CBR approach.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
