Which of the following is a common objective in scheduling optimization?

  1. Minimizing the total completion time of a set of tasks

  2. Maximizing the utilization of resources

  3. Minimizing the makespan of a project

  4. All of the above

Show answer
Correct Option: D
Explanation:

In scheduling optimization, the objective is often to minimize the total completion time of a set of tasks, maximize the utilization of resources, and minimize the makespan of a project.

What is the primary difference between deterministic and stochastic scheduling?

  1. Deterministic scheduling assumes known task durations, while stochastic scheduling assumes random task durations

  2. Deterministic scheduling uses exact methods, while stochastic scheduling uses approximate methods

  3. Deterministic scheduling is always more efficient than stochastic scheduling

  4. None of the above

Show answer
Correct Option: A
Explanation:

The primary difference between deterministic and stochastic scheduling is that deterministic scheduling assumes known task durations, while stochastic scheduling assumes random task durations.

Which of the following is a common scheduling algorithm used in practice?

  1. First-Come-First-Served (FCFS)

  2. Shortest-Job-First (SJF)

  3. Round-Robin (RR)

  4. All of the above

Show answer
Correct Option: D
Explanation:

First-Come-First-Served (FCFS), Shortest-Job-First (SJF), and Round-Robin (RR) are all common scheduling algorithms used in practice.

What is the main idea behind the Earliest Deadline First (EDF) scheduling algorithm?

  1. Assign higher priority to tasks with earlier deadlines

  2. Assign higher priority to tasks with longer durations

  3. Assign higher priority to tasks with more dependencies

  4. None of the above

Show answer
Correct Option: A
Explanation:

The main idea behind the Earliest Deadline First (EDF) scheduling algorithm is to assign higher priority to tasks with earlier deadlines.

Which of the following is a common technique used to improve the performance of scheduling algorithms?

  1. Resource leveling

  3. Load balancing

  4. All of the above

Show answer
Correct Option: D
Explanation:

Resource leveling, task clustering, and load balancing are all common techniques used to improve the performance of scheduling algorithms.

What is the makespan of a project?

  1. The total time required to complete all tasks in the project

  2. The time required to complete the critical path of the project

  3. The time required to complete the longest task in the project

  4. None of the above

Show answer
Correct Option: A
Explanation:

The makespan of a project is the total time required to complete all tasks in the project.

Which of the following is a common measure of the performance of a scheduling algorithm?

  1. Average waiting time

  2. Average turnaround time

  3. Resource utilization

  4. All of the above

Show answer
Correct Option: D
Explanation:

Average waiting time, average turnaround time, and resource utilization are all common measures of the performance of a scheduling algorithm.

What is the critical path of a project?

  1. The longest path from the start node to the end node in the project network

  2. The shortest path from the start node to the end node in the project network

  3. The path with the most tasks in the project network

  4. None of the above

Show answer
Correct Option: A
Explanation:

The critical path of a project is the longest path from the start node to the end node in the project network.

Which of the following is a common heuristic used for solving large-scale scheduling problems?

  1. Genetic algorithms

  2. Simulated annealing

  3. Tabu search

  4. All of the above

Show answer

Explanation:

Genetic algorithms, simulated annealing, and tabu search are all common heuristics used for solving large-scale scheduling problems.

What is the main idea behind the Critical Path Method (CPM) for project scheduling?

  1. Identify the critical path of the project and focus on completing the tasks on the critical path first

  2. Identify the non-critical tasks and focus on completing them first

  3. Identify the tasks with the most dependencies and focus on completing them first

  4. None of the above

Show answer
Correct Option: A
Explanation:

The main idea behind the Critical Path Method (CPM) for project scheduling is to identify the critical path of the project and focus on completing the tasks on the critical path first.

Which of the following is a common technique used to reduce the makespan of a project?

  1. Resource leveling

  2. Task clustering

  2. Estimate the duration of each task in the project using a deterministic value

  3. Identify the critical path of the project

  4. None of the above

Show answer
Correct Option: A
Explanation:

The main idea behind the Program Evaluation and Review Technique (PERT) for project scheduling is to estimate the duration of each task in the project using a probability distribution.
