软件工程第二次作业

8.5 The department of public works for a large city has decided to develop a Web-based pothole tracking and repair system(PHTRS). Draw a UML use case diagram for the PHTRS system. You’ll have to make a number ofassumptions about the manner in which a user interacts with this system. A description follows:

• Citizens can log onto a website and report the location and severity of potholes. As potholes are reported they are logged with a “public works department repair system” and are assigned an identifying number, stored by street address, size(on a scale of 1 to 10), location(middle, curb, etc.),district(determined from street address), and repair priority(determined from the size of the pothole). Work order data are associated with each pothole and include pothole location and size, repair crew identifying number, number of people on crew, equipment assigned, hours applied to repair, hole status(work in progress, repaired, temporary repair, not repaired), amount of filler material used, and cost of repair (computed from hours applied, number of people, material and equipment used). Finally, a damage file is created to hold information about reported damage due to the pothole and includes citizen’s name, address, phone number, type of damage, and dollar amount of damage, PHTRS is an online system; all queries a to be made interactively.
