Difficulty: Easy
Correct Answer: (b) and (c)
Explanation:
Introduction / Context:
Manufacturing processes are broadly categorized as discrete, continuous, or batch. This question focuses on discrete parts processes, where individual units are produced and operations are typically executed in repeatable sequences at workstations or on assembly lines.
Given Data / Assumptions:
Concept / Approach:
Discrete manufacturing emphasizes unit by unit flow, changeovers, and work in progress control. The repetitive nature enables standard cycle times, takt alignment, and quality checks per unit. This is distinct from continuous processes that transform materials without discrete unit boundaries.
Step-by-Step Solution:
Verification / Alternative check:
Production line studies show standardized work cycles and repetitive operations as hallmarks of discrete manufacturing.
Why Other Options Are Wrong:
Option a is incorrect because discrete versus continuous is not merely a controller choice. Option e is invalid because b and c are accurate. Choosing only b or only c misses the full characterization, therefore option d is best.
Common Pitfalls:
Assuming all repetitive operations imply high volume only; discrete processes can be high mix with frequent changeovers.
Final Answer:
(b) and (c)
