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.
Activity...Predec (Normal) Time..Cost..(Crash)Time.......Cost..........Cost/Day
a - 5 $50 3 $150
b - 4 40 2 200
c B 7 70 6 160
d a, c 2 20 1 50
e a, c 3 30 - -
f b 8 80 5 290
g d 5 50 4 100
h e, f 6 60 3 180
(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.
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;Normal Time;Normal Cost;Crash Time;Crash Cost;Crash Cost/Day
(c). Find the optimal way of getting an 18-day delivery time. What is the projected cost? You may use MS Excel (Solver) to find the optimal way of getting to an 18-day delivery time and copy/paste your table here or create a table in MS Word and enter the results in the table. Once you've found the solution, explain the results of your calculations.
(d). Find the optimal way of getting a 16-day delivery time. What is the project cost. You can repeat the process here for this question (Excel using Solver) or create a table and enter the results here to determine a 16-day delivery time. Explain your results.
(e). Calculate the shortest delivery time for the project. What is the cost? You can repeat the process here for this question (Excel using Solver) or create a table and enter the results here to determine the shortest delivery time. Explain your results.
