Question

-All constraints and linear programs should be derived with explanation and hand written. Linear programs (when asked for) should then be written in COMPLETE PROPER FORM (ALL constraints , organized order and clear identi cation of variable meanings).
ˆ All diagrams and graphics should be presented (repeated) enough times to clearly demonstrate the work process that was followed in carrying out your work. Legibility is necessary.
ˆ Excel can be used for calculations, but the pdf of this work must be \hand" augmented with clear indications of what was being carried out
ˆ Excel sheets involving solver must be fully explained and the solver window itself should be screen capped and submitted as part of your presentation to show the linear program you
asked excel to solve.

 

This is the Steps please follow.

• Develop a report which presents the PERT diagram and determines the Expected time
for the project. Include an explanation with details of what the worst case time is and
what the best case time is.
What is the probability of the complete project being done in under 1 year (52 weeks)?
in under 11 months (48 weeks)?
We have just been asked to speed up the project to be ready in 48 weeks. This will require
Some additional finances to get the tasks to complete by their best ease times as necessary.
As such the following information has heen complied:.
