schedulerelated

Schedulerelated is a term used to refer to topics tied to schedulers and scheduling, spanning domains such as computer systems, manufacturing, and services. It covers theories, algorithms, and practical implementations for ordering tasks, allocating resources, and meeting timing constraints.

In computer systems, scheduling determines which process or thread runs on a CPU, I/O device, or network link. Objectives include minimizing waiting time, maximizing throughput, and meeting deadlines. Common algorithms include first-come, first-served; shortest job first; priority-based; round robin; and multilevel feedback queues. Real-time scheduling distinguishes soft from hard deadlines and includes approaches such as rate-monotonic and earliest-deadline-first.

In operations research and manufacturing, scheduling focuses on arranging jobs on machines to minimize makespan or lateness. Classic problems include job-shop, flow-shop, and open-shop scheduling. Methods range from exact algorithms to heuristics and metaheuristics. Scheduling also appears in services and logistics, such as appointment systems, staffing, and shipping planning.

In software engineering and distributed systems, schedulers orchestrate workflows, cron-like tasks, or asynchronous job queues (examples include various task queues, workflows, and automation tools). In cloud and containerized environments, schedulers manage resource provisioning and task placement across compute resources. Evaluation of scheduling approaches uses metrics such as utilization, turnaround time, waiting time, response time, and deadline miss ratio; effectiveness depends on accurate workload models and constraints.
