You may need to use the appropriate technology to answer this question. Use the following network with activities and times estimated in days to answer the questions. A project network with 13 activities and 17 directed arcs is shown. Activity Start is connected to activity A, to activity B, and to activity C. Activity A is connected to activity D, to activity E, and to activity F. Activity B is connected to activity F. Activity C is connected to activity G and to activity H. Activity D is connected to activity K. Activity E is connected to activity I. Activity F is connected to activity I. Activity G is connected to activity I. Activity H is connected to activity J. Activity I is connected to activity K. Activity J is connected to activity K. Activity K is connected to activity Finish. Activity Finish has no arcs directed to other activities.

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.

(f) What is the probability that the project is completed in 22 or fewer weeks. (g) What date should be set such that there is a 94% chance of completion within that time?
Consider the project network pictured. Assume that the timesattached to each node are the means and the variances of the project completion times, respectively.a. Identify all paths from nodes 1 to 6.b. Which path is critical based on the expected completion times?c. Determine the probability that the project is completed within 20 weeksassuming that the path identified in part (b) is critical.d. Using independence of paths A–C–E and B–F–G only, recompute the answer to part (c).e. Recompute the answer to part (c) assuming independence of the paths identified in part (a).f. Which answer, (c), (d), or (e), is probably the most accurate?
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?
The Cove at UP is looking to open a new location. Guillermo Santiago has been developing a project plan and has identified the following tasks, precedence relations, and normal task durations. \ tasks predecessors task duration start 0 A start 7 B A 20 C A 34 D B 39 E C,D 6 F D 15 G E,F 33 end G 0 Guillermo has studied project management at the University of Portland and knows that the starting and ending time of any task may be determined from the information in the table using the critical path method. Assume the following notation when answering the questions below: \ Metric Description ES Early start time for task EF Early finsh time for task LS Late start time for task LF Late finsh time for task TS Total slack for task FS Free slack for task IS Independent slack for task SS safety slack for task Please provide the CPM result for each of the following metrics: ES_{end} = LS_{D} = TS_{D} = EF_{G} = LF_{G} =

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
