Turkoglu, H; Polat, G and Akin, F D (2023) Crashing construction projects considering schedule flexibility: An illustrative example. International Journal of Construction Management, 23(4), pp. 619-628. ISSN 1562-3599
Abstract
Time and cost are two of the most important performance indicators of construction projects. Project crashing is one of the effective methods for solving time-cost trade-off problems. However, in some instances, consuming all of the crash durations of the activities may lead to inflexible schedules. This paper proposes a project crashing model that aims to achieve more flexible schedules by means of assigning a crash duration consumption rate to each activity based on the preferred scheduling strategy. The applicability of the proposed model is presented along with an illustrative example. The Monte Carlo simulation is also performed to verify whether the proposed model is useful or not. The results revealed that the proposed model is an effective tool as it maintains schedule flexibility and increases the probability of completing the project in the targeted project duration. The proposed model also provides a new perspective for schedulers to solve project crashing problems.

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
