4. Given the network plan that follows, compute the early, late, and slack times. What is the project duration? Using any approachm you Wish (e.g., trial and error), develop a loading chart for resource, electrical engineers (EE), and resource, mechanical engineers (ME). Assume only one of each resource exists. Given your resource schedule, compute the early, late, and slack times for your project. Which activities are now critical? What is the project duration now? Could something like this happen in real projects? Develop a loading schedule for each resource below. (Figure 8.3) EE ME
