Answer: The key assumptions of classic scheduling theory include deterministic task execution times, non-preemptive tasks, no resource constraints, and task independence. 1. Deterministic task execution times: - Valid example: tasks in a production factory line, where machines perform tasks in a controlled environment. - Invalid example: software development projects, where task durations are often unpredictable. 2. Non-preemptive tasks: - Valid example: single task embedded systems where a task must complete before another task can start. - Invalid example: multitasking operating systems like Windows or macOS, where tasks can be preempted and resumed later. 3. No resource constraints: - Valid example: systems with a large number of redundant resources or sufficient resources allocated to each task. - Invalid example: systems with limited resources, causing tasks to compete for resources like memory or processing power. 4. Task independence: - Valid example: tasks in a manufacturing process that do not rely on each other, like painting different objects independently. - Invalid example: software development projects with interdependent tasks, like building a feature in an application that relies on the completion of another task.
