Background Information:

Volvo Transport operates a comprehensive network of bus routes, requiring many employees. Bus drivers undergo specific training for each route to ensure competency. Each bus route is supported by a timetable that schedules multiple buses daily. The organization includes four bus depots tasked with the maintenance and cleaning of the buses. Each depot manages the buses for a specific set of routes and employs a depot manager, several mechanics, and cleaners.
