Abstract
Research on prioritizing construction activities that are critical to the timely completion of projects rests on a range of indexes that attempt to identify the critical path and capture uncertainty in the duration of project activities. However, these indexes have been shown to have major flaws. These flaws can be classified broadly into two categories: (1) incomplete representation of an activity's importance; and (2) problems in the mathematical representation of an activity's importance. This paper developed a new index that addresses the shortcomings of the available schedule-based indexes. The proposed index was applied to a real-life construction project to evaluate the significance of its activities. The results confirmed the substantive influence of the structural organization of the project network on the relative importance of project activities. The key contribution of this research is to offer a richer approach to measuring the importance of construction activities by paying simultaneous attention to uncertainty in completion time, the total float, and the topological characteristics of project activities.

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
