The following activities are part of a project to be scheduled using CPM:
| ACTIVITY | IMMEDIATE PREDECESSOR | TIME (WEEKS) |
| A | — | 6 |
| B | A | 3 |
| C | A | 7 |
| D | C | 2 |
| E | B, D | 4 |
| F | D | 3 |
| G | E, F | 7 |
b. What is the critical path?
A-C-D-E-G
A-C-D-F-G
A-B-E-G
c. How many weeks will it take to complete the project?
d. How much slack does activity B have?
The following represents a project that should be scheduled using CPM:
| TIMES (DAYS) | ||||
| ACTIVITY | IMMEDIATE PREDECESSORS | a | m | b |
| A | — | 1 | 3 | 5 |
| B | — | 1 | 2 | 3 |
| C | A | 1 | 2 | 3 |
| D | A | 2 | 3 | 4 |
| E | B | 3 | 4 | 11 |
| F | C, D | 3 | 4 | 5 |
| G | D, E | 1 | 4 | 6 |
| H | F, G | 2 | 4 | 5 |
b. What is the critical path?
A-D-F-H
B-E-G-H
A-D-G-H
A-C-F-H
c. What is the expected project completion time? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
d. What is the probability of completing this project within 16 days? (Use Excel’s NORMSDIST() function to find the correct probability for your computed Z-value. Do not round intermediate calculations. Round “z” value to 2 decimal places and final answer to 4 decimal places.)
