Based on historical weather data, a particular project is expected to be impacted by 6 adverse weather days. Using one of the procedures described in this chapter, make the appropriate allowance for adverse weather and solve the network for the basic scheduling information. For each activity, .show the computed value of early start, early finish, late start, late finish, total float, and free
float.
What will be an ideal response?
There are a variety of answers that might be given for this problem. One
suggestion in the text was to include a weather delay activity late in the network. This has
been done below by the addition of activity "W". Adjustments could also be made to the
individual activity durations. This would result in fractions of days unless some type of
rounding was employed. Regardless of the approach, the six days of weather delays must
be incorporated such that the duration is extended by six days.
