The study is made for Pakistan  International Airlines (PIA) which operates both on domestic and international routes a The Airline operates a fleet consisting of different types of aircrafts. If the fleet size is known or fixed in advance, the cost of operation is minimized with the help of an optimal allocation of various aircraft types to fly on various routes in each period, where period is one calendar year. If the fleet size can be made variable, the fixed or holding costs can also be minimized by holding an optimal (minimal) fleet in each period. Thus the total fixed cost and cost of operation are minimized by an optimal (minimal) fleet in each period and a simultaneous decision on an optimal allocation of various aircraft types to fly on various routes in each period. An estimation of the number of passengers likely to travel along various routes over the planning horizon and data for the operational and fixed costs of each aircraft type were provided by the airline. Integer linear programming models are used to minimize the costs in the light of demand, operational,  budgetary, feasibility and availability constraints.  0aAir linesxManagementxMathematical models0 aTechapun Raengkhum , eChairperson1 aPakorn Adulbhan, eExamination Committee0 aSharif, M.
