Develop a project network/diagram based on the aforementioned data. Determine each activity's ES, EF, LS, LF, and SLACK/FLOAT. Determine the total project completion time. Determine the CRITICAL and the NON-CRITICAL paths.
FACTS:
Unmanned Aerial Vehicles (UAVs) are aircraft flown without humans on board. They are controlled remotely or have built-in navigation intelligence to determine their direction. We look at the decision situation of a developer who has just completed the prototype of a UAV and is putting together a more detailed proposal for commercial development. The data are as follows:
