Abstract
Proper management of the installation process in Modular Integrated Construction (MiC) is essential to achieve the time-saving benefit of MiC. The analysis of the installation process should cover its operational and contextual sides to realistically mimic the problem. In this connection, the parameters governing the operational and contextual realms of the MiC installation process were identified and investigated through literature; afterwards, a hybrid model was developed to estimate installation rate, duration, and cost of MiC projects. In this model, discrete event simulation was used to consider the operational aspects of the process, e.g. tasks, durations, and logical sequence, while system dynamics was utilized to capture its contextual factors, e.g. absenteeism, rework, resource utilization, fatigue, and weather conditions. BIM was used to feed the model by modules' coordinates and visualize the process. Monte Carlo simulation was adopted to tackle uncertainty and sensitivity analysis was performed to measure outputs variation. The study achieved its aim and objects and the model proved high sensitivity against resource variation and weather conditions, where it was concluded that doubling the resources would reduce the project duration by more than 50% and the weather conditions had an impact of 8.5% increase in project duration. Finally, the model was validated using a case study from the literature.

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
