QUESTION $1$

Precedence networks are essential in project scheduling as they clearly depict the logical order and interdependencies among jobs. They offer a systematic methodology for planning, assisting project managers in identifying critical paths, efficiently allocating resources, and anticipating potential bottlenecks. Precedence networks facilitate explicit communication of task interdependencies through several relationship types, including Finish$-$to$-$Start $($FS$),$ Finish$-$to$-$Finish $($FF$),$ Start$-$to$-$Start $($SS$),$ and Start$-$to$-$Finish $($SF$).$ Furthermore, by incorporating both interruptible and uninterruptible tasks, they provide flexibility in managing project timelines. Regardless of employing a straightforward or intricate methodology, precedent networks guarantee that even multifaceted projects are administered with lucidity and accuracy, hence enhancing the success of project execution.

a$)$ Explain the four types of relationships in precedence networks; Finish$-$to$-$Start $($FS$),$ Finish$-$to$-$Finish $($FF$),$ Start$-$to$-$Start $($SS$),$ and Start$-$to$-$Finish $($SF$)$ relationships. Provide examples of how each relationship is applied in project scheduling.

b$)$ Discuss the differences between interruptible and uninterruptible activities and how they affect the development of precedence networks in project scheduling.

c$)$ Compare the simplistic and detailed approaches to precedence networks.
