مستخلص: Given a schedule of flight legs to be flown by an airline, the fleet assignment problem is to determine the minimum cost assignment of flights to aircraft types, called fleets, such that each scheduled flight is assigned to exactly one fleet, and the resulting assignment is feasible to fly given a limited number of aircraft in each fleet. Then the airline must determine a sequence of flights, or routes, to be flown by individual aircraft such that assigned flights are included in exactly one route, and all aircraft can be maintained as necessary. This is referred to as the aircraft routing problem. In this paper, we present a single model and solution approach to solve simultaneously the fleet assignment and aircraft routing problems. Our approach is robust in that it can capture costs associated with aircraft connections and complicating constraints such as maintenance requirements. By setting the number of fleets to one, our approach can be used to solve the aircraft routing problem alone. We show how to extend our model and solution approach to solve aircraft routing problems with additional constraints requiring equal aircraft utilization. With data provided by airlines, we provide computational results for the combined fleet assignment and aircraft routing problems without equal utilization requirements and for aircraft routing problems requiring equal aircraft utilization.

مستخلص: The article reports that the FAA and European counterpart DGAC issued airworthiness directives man-dating inspections of rudders on certain Airbus A310s, A300-600s, A330s and A340s. The directives come in the wake of a March 6, 2005 incident in which the rudder of an Air Transat A310 separated in cruise flight. The event occurred about 30 min. after Flight 961's departure from Varadero, Cuba. The A310 returned and landed without incident or injuries to the 270 on board the Canadian charter. According to DGAC directives, inspections showed that only the rudder front spar portion between the three servo control actuators and the lower rudder hinge arm down to rib zero remained on the aircraft.
