Most efficiently allocating resources in IT change management

Enterprises of today face the challenge of managing large, complex IT systems. Change management, especially scheduling of changes, is know to be one of the most challenging problems in managing IT operations. After the use of metrics was brought into change management, mapping quantitatively the management has become possible. In this paper, we propose an optimization model for IT change scheduling that most efficiently uses the limited resources. It divides change into actions of different IT infrastructures, and relates each action with both other actions of the same change and actions of other changes. And we use a small but realistic example to validate our model.
