- The product development group at “Griffin” Company has already worked on new computer software products that has potential to know a large market share. Via an outside source, London Management has learned that a competitor is working to bring a similar product to market. As a result, London's top management increased its pressure on the product development group. Group leaders have turned to CPM / PERT as an aid to scheduling remaining activities before new products can be brought to market. The estimated time of activity in a day is as follows a.Create the the network if it is accelerated according to the schedule above b.Find the cost and the duration c.Determine the path and critical activitiesA project has four activities that take 4, 3, 6, and 7 days, respectively. What is the totalcompletion time for the project?a. 3 days, because this is the minimum timeb. 7 days, because this is the maximum timec. 20 days, because this is the sum of the timesd. It is not possible to determine the total completion time from the given informationFive jobs must be scheduled for batch processing on a mainframe computer system. The processing times and the promised times for each of the jobs are listedhere.Job 1 2 3 4 5Processing time 40 min 2.5 hr 20 min 4 hr 1.5 hrPromised time 11:00 A.M. 2:00 P.M. 2:00 P.M. 1:00 P.M. 4:00 P.M.Assume that the current time is 10:00 A.M.a.

- De Law Construction has a gotten some construction jobs to build some starter housing units in a few areas. The building time for each housing unit to be completed as well as the date that each unit is to be completed is shown in the table below. Today is Day 471. Which of the sequences, EDD OR SPT should the company use to sequence the order in which they do the jobs, assuming that because of resource constraints it cannot do the jobs simultaneously? HOUSING UNIT Building Time (days) Due Date Marabella 39 Day 502 Tabaquite 23 Day 528 San Juan 30 Day 515 Mayaro 33 Day 498 D’Abadie 41 Day 535 Preysal 40 Day 510 Some time after starting the jobs according to the sequence you decided on, it was found that because of inclement weather the last three housing units in the sequence have been delayed.

- In reference to the attached image: Activity times with the greatest uncertainty are activities D, E, and H. Describe conceptually how you could model this uncertainty in activity times. (You do not have the necessary data to actually do this numerically.)Liam is estimating the schedule for all activities in the GHI Project. He is working with his project team and comparing the results of a past similar project to forecast the schedule for his current project. This is an example of which estimating approach? Group of answer choices Analogous Organizational process assets Parametric PERTA manufacturer is designing a product layout for a new product production. It plans to use a production line for 8 hours per day in order to meet forecasted demand of 100 units per day. The product requires 7 tasks in total. These tasks are namely, A, B, C, D, E, F, and G respectively. Task A does not have any predecessor to start. To start Task B, it requires Task A to be completed. Starting tasks C needs, the task B to be completed. Also, starting task D needed task B to be completed. Task E can only start upon completion of Task C. Whereas starting task F needs the completion of both the tasks D and E. Finally, starting task G needed, task F to be completed.
