Constraints define the boundaries within which a valid schedule must operate, while optimization targets represent the objectives the schedule aims to achieve. Unlike traditional scheduling methods that may rely on templates or manual assignments, AI-powered scheduling systems can consider the entire solution space simultaneously.
- Hard Constraints: Non-negotiable rules that must be satisfied for a schedule to be valid, such as minimum staffing requirements, maximum working hours, or legal compliance issues.
- Soft Constraints: Desirable conditions that should be met when possible but can be violated if necessary, like employee preferences or optimal skill distribution.
- Optimization Objectives: Goals the scheduling system seeks to maximize or minimize, such as labor costs, coverage quality, or employee satisfaction scores.
- Constraint Hierarchies: Prioritization frameworks that help resolve conflicts between competing constraints based on their relative importance.
- Solution Space: The set of all possible schedules from which the optimization algorithm selects the best option according to defined criteria.
