Difficulty: Easy
Correct Answer: all of these
Explanation:
Introduction / Context:
Predetermined Motion Time Systems (PMTS) such as Work-Factor (WF) and Method-Time Measurement (MTM) provide standard times from motion data without stopwatches. Abbreviated Work-Factor (AWF) streamlines WF to estimate times quickly for broader industrial tasks.
Given Data / Assumptions:
Concept / Approach:
AWF aggregates motion categories so analysts can set reasonable standards across diverse tasks. Material handling (lifting, carrying, placing), maintenance (walking, reaching, tool handling), and packing/shipping (selecting, wrapping, labeling, palletizing) all feature motions that suit AWF-level detail.
Step-by-Step Solution:
Identify AWF strengths: rapid estimates for varied manual tasks.Map to shop functions: handling, maintenance, and logistics involve similar motion families.Hence, AWF applies to all listed areas.
Verification / Alternative check:
Industrial engineering texts position AWF for broader applications beyond fine bench assembly, which may require more granular PMTS (e.g., MTM-1).
Why Other Options Are Wrong:
Options (A), (B), and (C) are each true but incomplete; (E) is too narrow and not typical for abbreviated data.
Common Pitfalls:
Using overly detailed systems where quick estimates suffice; conversely, using AWF where micro-motions dominate and precision is required.
Final Answer:
all of these
