The "Last-Come, First-Served" (LCFS) principle is a method of resource allocation where the most recently arrived items or individuals are the first to be served or processed. This approach is commonly used in various settings, such as queues, customer service, and inventory management. It ensures that the latest entries receive priority, which can be beneficial in situations where freshness or timeliness is crucial. In practice, LCFS can be seen in scenarios like restaurants where late arrivals are seated before earlier ones, or in computer systems where the most recent tasks are executed first. This method contrasts with other systems, such as First-Come, First-Served (FCFS), which prioritizes those who arrive first.
