Only question 2

1. Problem 1 (15pt) Innovative Networks Inc. was granted a contract to set up a telecommunication network for a new football stadium. The project manager has identified eight critical steps in creating the telecommunication network. The following table lists these steps, their planned durations and the predecessor(s) for each step. Duration Immediate Activity Job Description (in weeks) Predecessor(s) Perform assessment 2 B Design network control software 18 Construct antenna terminals Wire fiber optic cables E Position routers F Install processors 5 CD Initial hardware testing 3 E,F H Final network testing BG C 10 D a. Draw an activity-on-node (AON) network diagram for the project (2pt) b. Compute the early start (ES), carly finish (EF), late start (LS), and late finish (LF), and total slack (TS) for each activity. Display all values in a table format (10p) c. Determine the critical path(s) for the project. What is the length (in weeks)? (2pt) d. Which activities are non-critical? (1pt) Problem 2 (15pt) GameOn is a company focusing on virtual reality (VR) based gaming accessories. They plan to launch its new VR headset, the GameOn Adventure. The project manager identifies the critical steps in launching the product and the following network diagram represents the initial project plan (numbers in parenthesis represent activity duration in weeks). Note that the legend at the bottom of the network diagram indicates the format used to illustrate early start, early finish, late start and late finish times for each activity. ES EF LS LF Company's strategists believe that releasing the product 2 weeks earlier will significantly help the company rebuild its reputation and financial status. The following table lists activities that can be crashed and their associated costs: Activity Crash Cost per Week Maximum Weeks to Crash $85,000 $35,000 $90,000 $60,000 $80,000 $65,000 HT $70,000 a. Determine the most economical way to crash the project duration by two weeks. What is the incremental cost to complete this project two weeks earlier? (12pt) b. What is (are) the critical path(s) after crashing the project (3pt)
