An IT project manager of ABC Company has developed an activity list for the purpose oftracking employees' daily activities on the project. The project's schedule is considered to be ofhigh risk due to the possibility of sabotage by some of the employees. In addition, the IT projectmanager has gathered time information for each activity, as shown in the table below. Considerthe following project's tasks and their identified best, likely, and worst case estimates of taskduration. Assume the organization computes PERT weight average based on the standardformula.Activity Optimistic MostPessimisticlikelyA25В38C78D44E101934F1418G1620H324465I121725J2818The dependencies between theactivities listed in the table above are as follows:The project starts with two activities-A, and B-which can be done concurrently.When activity A is finished, activity C can startWhen activity B is finished, activities D and E can startWhen both activities C and D are finished, activity F can startWhen activity E is finished, activity G can startWhen activity F is finished, activity H can startWhen both activities G and H are finished, activity I can startWhen activity G is finished, activity J can startThe project is complete when activities I and J are finishedQuestions1. Organize the information above in an activity precedence table showing the activity, precedentand duration (calculated using the PERT weighted average formula and round to thenearest integer).2. Draw an AON network diagram and calculate its early start, early finish, late start and latefinish times, floats (Free and total) for each activity. Make sure you fully label all nodes in thenetwork.3. Identify the project's critical path and its length.

The City of Rockland is planning to build a new fire station. A project manager and the project team have been selected. The project team is interested in selecting a project scheduling technique that will be used to complete the project. The criteria for the process of selecting the project scheduling technique has been established as follows: easy to use, and shows the following – task durations, milestones, flow of work, sequence of events, which tasks can be undertaken at the same time, and how far tasks are from completion. The City Manager favors the Gantt chart, the Fire Chief likes Program Evaluation and Review Technique (PERT), and the project manager prefers the Critical Path Method (CPM). Assume you are the project manager; which project scheduling technique would you choose? Discuss the rationale for your decision.
The North Carolina Department of Transportation is undertaking a construction project to widen a large section of interstate highway near Charlotte, NC, which includes the construction of a number of new bridges, interchanges, and overpasses. The first step in the project is the appointment of a project manager and the development of a project team, some of which will be departmental employees and others will be private consultants and operatives. The team of a project of this size also requires a large support staff with varying technical skills. Once the team is selected and the staff is in place the first task is to select a primary contractor to manage and oversee the actual construction. The following table gives the standard activities required for the planning and scheduling of this process.

Use the following network and the data to perform the following: a) Prepare the manpower loaded Gantt chart with total floats of this project using early start and late times. Plot the manpower resource profile that shows the total number of laborers per day over the course of the project. Prepare the Gantt chart and the resource profile using the early start and finish dates of activities (not necessary to produce the late start and finish charts). b) Level the manpower resource given the constraint that the owner has only 14 workers to allocate to this project per day. Please try to do in excel. Thannks
A student in the project management course takes no less than 20 minutes to solve a typical network problem and sometime, as much as 50 minutes. However, the most frequent time taken usually by students is 30 minutes for the same network. If one has to solve using PERT, then calculate the (i) expected time and variance to solve the network (ii) maximum and minimum allocated time to solve the network
A contractor needs to complete a project. The project involves 10 activities (labeled A, B, ..., J) with precedence relationship in network below. The estimate (in weeks) of the duration of each activityis in the table below. a. The mean and variance of the activity time for A~F are given in the table. Find the mean and variance of the activity time for the remaining arcs.b. Identify the critical path and then compute the mean and variance of the project completion time.c. What is the probability that the project is completed between 32 and 36 weeks?d. What completion time should the contractor claims to be 95% sure of completing the project by then?

A project is scheduled to complete in six months duration. There are two activities in the project. The actual cost of Activity 1 is SAR 300,000 and that of Activity 2 is SAR 200,000. The planned value of these activities is SAR 280,000 and 150,000 respectively. On reviewing, the current project status is Activity 1 is 100% completed and Activity 2 is only 75% completed. (i) Perform the earned value calculations of the above project scenario and fill the given table. Activity Month 1 Earned Value Planned Value Actual Cost Cost Variance Scheduled Variance Cost performance Index Schedule performance Index (ii) What do you infer about the project schedule and cost based on your calculations?
A given task was estimated to cost $15,750 to complete. Currently, the project team has completed approximately 65% of the task, and have spent $10,500. a. Determine the indices: AC, PV, and EV b. Derive the values for cost and schedule variances, as well as cost performance and schedule performance indices. Is this project ahead or behind on schedule, and is it ahead or behind on budget?
In making a forward pass through a network, three activities are immediate predecessors for activity T and one following activity. What is the late start time for activity T? Group of answer choices: - the LS of the following activity plus the activity time of T - the smallest EF for the three activities that are immediate predecessors for activity T - the LF of the following activity minus the activity time of T - the LS of the following activity minus the activity time of T - the largest EF for the three activities that are immediate predecessors for activity T
Patel and Associates, Inc., is an accounting firm that has three new clients. Project leaders will be assigned to the three clients. Based on the different backgrounds and experiences of the leaders, the various leader-client assignments differ in terms of projected completion times. The possible assignments and the estimated completion times in days are as follows. Project Leader Client 1 Client 2 Client 3 Jackson 10 16 32 Ellis 14 22 14 Smith 22 24 34 Formulate the problem as a linear program. (Express your answers in the form xij where xij is 1 if leader i is assigned to client j and 0 otherwise.) Then solve: Relationship Value Time (Days) x11 x12 x13 x21 x22 x23 x31 x32 x33
