A method and apparatus directed to receiving maintenance demands and historical maintenance data associated with maintenance items are presented. A plurality of models that each define locations, maintenance items, resources, cycles, and average performance is generated, wherein each model represents a hypothetical scenario adjustable by a user so that a model representing one scenario may be compared alongside another model to view the differences in result for various hypothetical scenarios. One or more plans are generated for each model and take into account the received maintenance demands and historical maintenance data. A work package is generated in view of the received maintenance demands and historical maintenance data and the plan.
