Scheduling the Peacetime Rotation of Pakistan Army Units
Abstract
Since Pakistan has greatly varying climates and terrains, the Pakistan Army rotates its units between locations so that no unit endures inequitable hardship or enjoys unfair advantage. Army peacetime policy specifies strict constraints on unit rotations, including restriction on: the length of a unit's stay in any location, the number of units moving at any time, and the allowable replacements for any moving unit. Scheduling rotations manually in accordance with these rules, as is currently practiced, is extremely difficult and time-consuming. This thesis presents an integer programming model that finds feasible, minimum-cost schedules for planning horizons of up to eight years. The model also ensures that the units are positioned at the end of the planning horizon so that feasible schedules exist for future planners. The model is implemented with commercially available software: the GAMS algebraic modelling language and the XA and OSL optimizers. Schedules are obtained for realistic test problems in less than an hour on a 486/33 personal computer.
