Abstract
This paper focuses on the application of "combined simulation modeling" to achieve more accurate and flexible modeling of random processes affecting construction progress. In particular, a model is presented where a project schedule prepared using the critical path method (CPM) is transferred into a process interaction-discrete event simulation model and then combined with a continuous change weather process in the same model. The combined approach provides certain advantages to other methods. It is more effective than deterministically adding the expected delay due to weather to the expected duration of the project estimated from CPM, for example. It is also more accurate than using straight Monte Carlo-simulation of the CPM schedule or discrete event simulation modeling. The paper also provides an overview of the various aspects of implementing the combined model including use of mathematical and statistical methods to model weather processes and trained neural networks to estimate the effects of weather on productivity.

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
