Which of the following is NOT a major component of a queuing system?

• A. The queue discipline
• B. The service mechanism
• C. The arrival process
• D. The production possibility frontier

Answer: (D)

Verified step by step guidance

1. Step 1: Understand what a queuing system is. A queuing system models the process of customers or items arriving, waiting in line, and being served. It is commonly analyzed in operations research and microeconomics to optimize service efficiency.
2. Step 2: Identify the major components of a queuing system. These typically include: the arrival process (how customers arrive), the service mechanism (how customers are served), and the queue discipline (the order in which customers are served).
3. Step 3: Recognize that the production possibility frontier (PPF) is a concept from microeconomics that illustrates trade-offs in production between two goods, and is unrelated to queuing systems.
4. Step 4: Compare the options given: queue discipline, service mechanism, arrival process, and production possibility frontier. Since the first three are fundamental parts of queuing theory, the PPF does not belong to the components of a queuing system.
5. Step 5: Conclude that the correct answer is the production possibility frontier because it is not a component of a queuing system but rather a separate economic concept.
