This question is about a repetitive project with the five sequential activities, each with different manpower requirement.
00:08
Here we have to calculate the production level specific and a calculation based on the working hours and unit of works.
00:17
So first we have to calculate the various parameter.
00:20
So first calculate the total project duration.
00:26
Activity a is equal to 100 man hours multiplied by 4 men which is equal to 400 man hours.
00:36
B is equal to 350 multiplied by 6 which is 2100 and c is equal to 60 multiplied by 2 which is 120.
00:46
200 multiplied by 5 is equal to 1000 and activity e is equal to 150 man hours multiplied by 8 men is equal to 1200 man hours.
00:57
So the total man hours per unit is equal to we add all the activity of man hours.
01:04
So 400 plus 2100 plus 120 plus 1000 plus 1200 is equal to 4820 man hours.
01:15
So the productivity demand is equal to 3 section per week multiplied by 20 units, which is equal to 60 section and total project duration in weeks is equal to total man hours divided by productivity demand into working hours per week.
01:35
So putting the values of this 4820 divided by 60 multiplied by 8 multiplied by 5 which is approx 2 .01 weeks.
01:49
Now coming to the second calculation of this equation average time gap between first and the last unit...
