Answer:
Expected project duration is determined as a direct result of computing the earliest starting and finishing times for the activities of a project network.
Step-by-step explanation:
In project management, early start is the earliest moment at which a specific activity may start and early finish the earliest moment at which it can end. Early finish (es) is computed as:
EF = ES + d
where d is the activity duration and ES early start
Early start is computed as
ES: Max (EF-1)
or the maximum early start of predecessory activities.
Once we have calculated these values in the network for each activity , the early finish of last activity corresponds to the expected project duration, the earliest time in which we may finish the project if there are no issues.
Max project duration is open question as we could have infinite delays or never finish the project. Time variance in project duration may only be estimated once we have actual execution times of our project.
Slack time and critical path are obtained after obtaining the ES and EF but this info alone is not sufficient. We require either the late start or the late finish of the activities to calculate slack, Zaero slack activities, those that cannot be delayed form critical path and can only be obtained after having ES. EF. LS and LF
Answer:
c I had the same worksheet
Step-by-step explanation:
Answer:
Step-by-step explanation:
3x-12 ≥7x+4
Subtract 3x from both sides
-12 ≥4x+4
Subtract 4 from both sides
-16 ≥4x
Divide each side by 4
-4 ≥x
From point 4, you use a closed circle and the arrow is facing towards 0
