To complete the rotor assembly for an experimental spacecraft, Gilbert has laid out nine major activities involved. These activities have been labelled A to I in the table below, which also shows their estimated completion times (in weeks) and their immediate predecessors.

For the following simple seven‐activity project, develop a precedence network, calculate all relevant characteristics of each activity (ES, EF, LS, LF, TF), and calculate the project duration. Then draw a time‐scaled network and under it a labor resource histogram for the ES. Do the same for the LS. In both cases, use the maximum allowable number of workers. Make adjustments to the noncritical activities, within the constraints of the ES and LF and the maximum and minimum workers allowed to provide what you feel is the best labor distribution. Lastly, Explain in detail what do you feel is the biggest problem with the ES and LS configurations, and how has this been alleviated with your solution?
The managers at AllBirds have operations in multiple countries, which operate on different financial management systems. This has been increasingly challenging for the company, so the Justin is looking to consolidate and integrate the financial management across all locations into a single software system that can operate across the national boundaries. This is a new, complicated and lengthy project, so Justin has identified a set of activity categories that will need to be carefully managed, as noted in the table. Draw the project network, and compute the expected time and variance for each activity. Develop an activity schedule for this project, compute activity slack time and identify critical path.
The conditions and pert times for constructing a network diagram are given below.-Creation conditions:(0-1) It is the initial activity.(1-2) and (1-3) Activities begin together.It follows activity (2-4) (1-2), activity (3-4) (1-3), and ends together.( 4-5 ) It is the last activity. a-Create the network diagram.b-Calculate the critical path and show it on the diagram.c- If the expiry time is extended by 15 days, how much will the probability of expiry increase?
The following table shows activities with duration, dependency, dependency type, and the number of workers from one small segment of a project network. Draw the segment of the network diagram and then: (a) Show the resource usage (chart) if activities A, B, and C start on day one; (b) Show the new network diagram and the resource usage (chart) when resources are leveled after applying appropriate slack times.

Why is it critical to determine the sequence of activities in a project? Discuss diagrams that resemble network diagrams that you have seen. Compare and contrast their characteristics.
GreenzTech Inc. is planning on installing a new computerised accounting system. For thisproject, they have established the following activities, precedence relationships, and timeestimates in weeks:a. Draw the network diagramb. Calculate the expected time for each activity.c.

What is the activity variance along the critical path?g. What is the probability of completion of the project within 50 weeks or less?
