Respuesta :
The slack can easily be explained as the difference between latest start (ls) and earliest start (es) of an activity.
As the above example, we can easily now calculate slack as the follow:
slack = LS - ES or LF - EF
So, the correct answer will be
LS - ES = 14 -12 = 2
or LF - EF = 20-18 = 2
So, the slack associated with this activity is 2.
The amount of slack associated with this activity is 2.
Further Explanation:
Slack:
Slack is the time period, the activity can be delayed with this limit with completing the project on time. The project should be completed within the timeframe of the project. If one activity is delayed due to any reason, all other activity is delayed. Thus, the whole project is delayed with the time period one activity is delayed.
The full form of es is the earliest starting time. The full form of ls is the latest starting time. The full form of ef is the earliest finish time. The full form of lf is the latest finish time.
Given information:
Es = 12
Ef = 18
Lf = 20
Ls = 14
Compute the slack associated with the activity:
The slack is computed by two methods. One method of calculating the slack is taking the difference of the earliest starting time and the latest starting time. Another method of calculating the slack is taking the difference of the earliest finish time and the latest finish time.
Slack= Latest finish time – Earliest finish time
= 20 – 18
= 2
Slack= Latest starting time – Earliest starting time
= 14 – 12
= 2
Therefore, the activity can be delayed for 2 days, if the activity is delayed for more than 2 days. The project is not completed on time.
