$10\mathrm{.}1$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 $10\mathrm{.}10.$ Develop a schedule that minimizes resource fluctuations.
