Airlines Fleet Management analysis and design model

I require assistance in producing an analysis model & design model for the system through use case diagrams and document template as attached. See attached file for full problem description.

Fleet management provides information on and maintenance scheduling facilities for the airline's fleet. The airline flies four different aircraft: the Boeing 737 and Airbus A310 on short-haul flights and the wide-bodied Boeing 747 and Airbus A380 on long-haul and busy routes. The fleet management system allows maintenance tasks to be scheduled for each plane in the fleet. There are four categories of maintenance:
? Seating reconfiguration - This allows a manager to assess a plane in order to reconfigure the seating arrangement, including how many seats are allocated to each class of travel. Reconfiguration takes six hours to complete.
? Light overhaul - This is when the engines and flight controls are overhauled and the rest of the plane is inspected. A light overhaul takes one week to complete for regular aircraft and two weeks for wide-bodied aircraft. A light overhaul must be done every 1000 hours of flight time.
? Complete overhaul - This is when a plane is stripped down to its skeleton and all parts are replaced or overhauled. A complete overhaul takes four weeks for regular aircraft and six weeks for wide-bodied aircraft. A complete overhaul must be done every 10,000 hours of flight time.
? Emergency maintenance - This is when a fault occurs on a plane that is supposed to be in service and must be fixed as soon as possible. An estimate of time to complete is given with this request.

When a maintenance task is scheduled, it is allocated to a maintenance base. Currently, the airline has three maintenance bases: one in Europe, one in Asia and one in North America. A plane may have several maintenance tasks scheduled (e.g., it may have three seating reconfigurations booked for future dates, a light overhaul for the near future and a complete overhaul in two year's time). The system should allow a manager to find out about all scheduled maintenance tasks over any time period, all tasks scheduled for a single aircraft or tasks scheduled for a particular maintenance base.

When seating reconfiguration is being planned, the system needs to ensure that the configuration will fit into the aircraft.
? B737 can have a maximum of 149 economy class seats.
? A310 can have a maximum of 247 economy class seats.
? B747 can have a maximum of 568 economy class seats.
? A380 can have a maximum of 840 economy class seats.
A first class seat on a wide-bodied aircraft occupies the equivalent of four economy class seats and the equivalent of three economy class seats on a regular aircraft. A business class seat on a wide-bodied aircraft occupies the equivalent of two and a half economy class seats and the equivalent of two economy class seats on a regular aircraft. An executive economy class seat on a wide-bodied aircraft occupies the equivalent of two economy class seats and the equivalent of one and a half economy class seats on a regular aircraft.

The fleet maintenance system allows customers to use a web interface to find out information about an aircraft, such as the configuration it will be in for a particular flight. Pictures of both the exterior and interior of the planes are available, along with a seating plan for each flight. Photos of the style of seat available in each class are also available. Wide-bodied aircraft provide more on-board facilities, including in-seat entertainment systems. Videos demonstrating these facilities can be viewed through this system.

The airline is planning to purchase light commuter aircraft within one year. These will be used on short flights to small, regional centres. They require that the design of the system be flexible enough to accommodate light commuter aircraft with minimal changes.
