The Fundamentals of Linear Programming in Scheduling Algorithms
Linear programming forms the mathematical foundation of many modern scheduling algorithms. At its core, linear programming is a technique for optimizing a linear objective function subject to linear equality and inequality constraints. In the context of employee scheduling, this translates to finding the optimal assignment of employees to shifts while satisfying various requirements. The mathematical elegance of linear programming allows scheduling systems to find the most efficient solution from countless possibilities, turning what would be an overwhelming manual task into a streamlined, data-driven process.
- Objective Function: Typically focuses on minimizing labor costs or maximizing coverage while maintaining service quality.
- Decision Variables: Represent whether an employee is assigned to a specific shift or task.
- Constraints: Include employee availability, minimum staffing requirements, maximum working hours, and regulatory compliance.
