Problem 1: Project Scheduling Problem (32 pts) 4. Assuming that activities which are not on the critical path(s) start at their earliest possible time, determine whether the following Gantt chart is correct or not. (6 pts) An engineering project is to be conducted. The following network diagram shows the involved activity numbering and their duration in days (within parentheses). OBIETER Well 111 Start SH (123 (10) Cand (211 a. True b. False 1. Determine the earliest time to complete the project using the critical path method (unit is not required). (8 pts) 5. Due to an unexpected incident, the duration of activity 14 has to be extended by 4 days. What is the new earliest completion time (no unit is required)? (6 pts) 2. How many critical paths do you find? (6 pts) 3. If you identify one critical path, how many activities are involved along this path? If you identify more than one critical path, how many activities are involved along the longest path (i.e. the path that has the greatest number of activities)? (6 pts)
