1 The following project is performed with a single type of resource (labor), which is assumed to be available in unlimited quantities.The resource usage rate is constant throughout the duration of each activity. Thus, if the duration of an activity is 5 days and it requires 60 hours of the resource, then of the resource are required each day that the activity is performed. The project data are shown in Table 3. Develop a schedule that minimizes resource fluctuations.
