PMAN635 Quantitative Methods in Project Management Session 9 - IA-9 PMAN635 Session 9 IA-9 Problem 1: Given the information provided below (predecessors, normal time, normal cost, crash time and crash cost for an eight-activity (a to h) project) answer the questions (a) through (e) using this template. Note: If there are no adequate explanations, points will be deducted even if the answers are correct. Activity Predecessor a b c d e f g h b a, c a, c b d e, f Normal Time 5 4 7 2 3 8 5 6 Normal Cost $50 40 70 20 30 80 50 60 Crash Time 3 2 6 1 5 4 3 Crash Cost Crash Cost/Day $150 200 160 50 290 100 180 (a). Create the network diagram in the application of your choice and then insert a screen shot of the diagram here. The diagram can be created easily in MS Word using the Insert Shapes function. Enter your network diagram in this space provided (you should delete this text box and use as much space as necessary to display your network diagram). Identify the critical path of the network, the time, and cost of the normal level of activity for the project: The critical path is: __________________ The project duration: ___________ The project cost is: _____________ (b).Calculate the crash cost-per-day (all activities may be partially crashed). Enter your response to question 1(b) in the table provided below Activity a b c d e f g Normal Time Normal Cost Crash Time Crash Cost Crash Cost/Day PMAN635 Quantitative Methods in Project Management Session 9 - IA-9 h (c).
