Fleet Management Company (FMC)

Transcription

1 Task Fleet Management Company (FMC) The Fleet Management Company (FMC) maintains fleets of vehicles leased by different corporations and organisations. The fleets are an essential part of the day to day business of many companies, and such must be maintained and ready for use at all times. The maintenance of the fleets involves scheduled repairs such as Serving and MOTs, and unscheduled repairs such as breakdowns. The cost of maintaining the fleets is a major overhead, and cutting this expenditure allows the companies leasing the fleets to invest more in other parts of the business or increases their profit. FMC offers its customers competitive maintenance contracts, and finds the garages that are able to repair the vehicles at the most competitive rate, in the local area. At the end of each year, FMC reviews all the garages that it used, and only uses the ones that faired well in the future. In this worksheet, you will be expected to write and alter program code designed to address the requirements of this application. The specific tasks are listed below. Purpose This document provides the specification for the provided example code. It provides an overview of the intended system and a description of the functions that are implemented in the example code. Use this document to help your understanding of the provided code. The following definitions apply to the interpretation of this scenario: Customer: the point of contact at the company using FMC services, who interacts with FMC the employee of the company who deals with reporting of the breakdowns. For example, this could be the fleet manager at certain company. Car: A single unit of the fleet, leased by a customer for which a maintenance agreement with FMC exists. Garage: A number of mechanics who will perform the repair work on behalf of FMC. Repair: A maintenance task that has been initiated as the result of a Customer report and assigned to a Garage to carry out the work. This can also be a scheduled activity such as a Service or MOT. Job Detail: Details of the repair work completed by the Garage. This may relate to the complete Job or to part of the Job. Typical Scenario The following describes a typical scenario that is to be recorded by the system. 1. A Car in a Customer fleet breaks down or is due for a scheduled maintenance. 2. The Customer report the issue to FMC, to ask for the car to be repaired. 3. FMC raises a Repair, and agrees a repair date with the Customer. 4. FMC, uses the system to identify the Car that the Repair relates to, and the appropriate Garage that will carry out the repair job. The Repair is assigned to the Garage. A Repair task may require one or more Garages to complete the Repair. 5. The Customer can monitor the progress of the Repair by logging into the system through a browser. 6. Each assigned Garage can access the system to add details of the Job (Job Detail) that needs to be completed. They may add one or more JobDetail entries depending on the complexity of the
