2B) Road Repair and Tracking Software (RRTS) to be developed for automatic various book keeping 3M activities associated with the road repairing task of the Public Works Department of the Corporation of large city. Road Repair and Tracking System (RRTS): A city corporation has branch offices at different suburbs of the city. Residents raise repair requests for different roads of the city. These would be entered into his computer system by a clerk. Soon after a repair request is raised, a supervisor visits the road and studies the severity of road condition. Depending on the severity of the road condition and the type of the locality (e.g.. commercial area, busy area, relatively deserted area, etc.), he determines the priority for carrying out work, the types and number of machine required, and the number and types of personnel required. Based on this data, the computer system should schedule the repair of the road depending up on the priority of the repair work and subject to the availability of raw material, machines, and personnel. This schedule report is used by the supervisor to direct different repair work. The manpower and machine that are available are entered by the city corporation administrator. He can change these data any time. Of course, any change to the available manpower and machine would require a reschedule of the project. The mayor of the city can request for various road repair statistics such as the number and type of repairs carried out over a period of time and the repair work outstanding at any point of time and the utilization statistics of the repair manpower and machine over any period of time.
