In Scheduler, transition cost is defined as the cost between an activity and the activity that will execute next to it on a unary resource. These costs may be related to modifications to the resource that require manpower, material, and energy, such as adjusting or purging a machine. In addition, Scheduler lets you define a setup cost for the activity that starts the usage of the resource, and a teardown cost for the activity that ends the usage of the resource. IloTransitionCost is used to model these costs that may occur for using an IloUnaryResource.
