Parameters represent characteristics or behaviors that can be attached to a scheduling object. For example, a scheduling object like a resource may have a maximal capacity that varies with time, or there may be break intervals during which activities executing on that resource may be suspended. Parameter classes represent these various characteristics, such as capacities, breaks, and transition times.
Concert Technology allows these characteristics to be shared between several scheduling objects. For example, several instances of resources may share the same break list (such as, all these resources have breaks on weekend), or several activities may share the same behavior with respect to breaks on resources. Sharing a characteristic saves memory in the model and allows easy modification of the value with only one function call for a group of objects.
