Development: Given the following PERT network modeling new home construction by Bonanza D 3 3 A 6 J L C 3 Start E 3 Finish K B 5 F 8 H 5 G 10 a) Prepare a table of the earliest and latest start and finish times and slack times for each activity in Bonanza's project. b) What is the critical path and the expected project completion time? c) Reliable Plumbers, the subcontractor performing activity J, is going to be delayed 5 weeks. If the project is delayed, it will cost Bonanza $2000 per week of delay of the entire project. Reliable is charging $3000 for the plumbing. Bonanza has three options: (1) Keep Reliable Plumbers. (2) Cancel the contract with Reliable Plumbers and hire Local Plumbers, Inc. Local Plumbers, however, will take two weeks to do activity J, and will charge $7000. (3) Bonanza can train its own employees who are currently performing activity E to do the work. This involves a two-week training period as soon as activity E is done. Then it is expected it will take them three weeks to perform activity J. The cost of the training is $800 per week and the cost of them doing activity J is $1,000 per week. Which alternative do you recommend to Bonanza? Explain
