1) Reduce total switch duration as much(prenominal) as possible without excess additional costs. Indicate the new critical raceway or caterpillar treads. Show how much remit cadence remains in the noncritical paths.
We assume that the question does not require a bound on the descend spent, and thus we can disassemble as much as possible provided no finances are used that would be wasted (eg. Crashing on a treat that is slack).
We looked at Exhibit 3 to see how much we can shipwreck each activity by. Looking at each 4 paths we calculated the shortest possible completion time for each path. If we crash as much as possible, we go bad these paths:
ADG = 7 weeks*
BG = 6 weeks
AF = 7 weeks*
CEG = 5 weeks
Of these, ADG and AF are both(prenominal) the new critical paths for which this process result be bounded. Thus, we ask to minimize the time for path ADG and AF down to 7 weeks and go out that the two other alternative paths will also crash to at least 7 weeks.
Crash Requirements for
Assignment| keep down of weeks reduced| Cost to crash per week| Total amount to crash|
A| 1| $5,000| $5,000|
F| 2| $3,000| $6,000|
G| 2| $7,000| $14,000|
D| 2| $4,000| $8,000|
Total| -| -| $33,000|
From the above reduction, path BG = 8 weeks, and it needs to be reduced down to 7 weeks. This can be done by reducing B from 6 weeks to 5 weeks and it costs another $6,000. As for the path CEG, it equals to 6 weeks, which is already smaller than the critical path. Therefore, it is slack and we do not have to make more modifications to it.
Thus this results with a total cost of crashing $33,000 + $6,000 = $39,000. And we see that the base price for the process will be $61,000 so with our crashing, we see the cost will be $100,000 to reduce the process time to 7 weeks.
The slack variables CEG has a path length of 6 weeks (since G was crashed by 2 weeks). Therefore we can delay either C or E by one week without changing the total process time,...If you want to get a sound essay, order it on our website: Orderessay
