Can you help with this question please?
I thought to calculate the lower bound the formula is
sum of all activity times
÷ critical time of project
Question:
Use your cascade chart to determine a lower bound for the number of workers needed. You must justify your answer.
Mark schemes answer: 4 workers needed e.g. at time 8 ½ (noon on day 9) activities E, D, F and G must be happening.
What does 8 1/2 have to do with anything? Edexcel past-papers use a whole different concept within past-papers than their own textbook..
How would you calculate the lower bound? In the textbook it states you must add up all activity times in the original critical path analysis chart and divide by critical time of project. But in past-papers it's a total different concept
I used the method of sum of all activity times
÷ critical time of project.
I added up all the activity times which is 59.
59
÷ 22 = 2.68 .... Rounding up means we need 3 workers.
A totally different answer from the mark scheme..
