IBM ILOG Scheduler User's Manual > Getting Started with Scheduler > Scheduler Building Blocks > Resource Constraints > Enforcement Levels

The enforcement level allows specifying how much effort the solver will expend enforcing a given resource constraint on a given resource. All enforcement levels ensure that any solution found by the scheduler will satisfy the type of constraint to the associated level. IloBasic is the default enforcement level. There are other enforcement levels that represent degrees of enforcement lower or higher than the IloBasic; for example, IloLow or IloHigh. Each level represents a certain degree of effort spent by the scheduler to enforce constraints.
