Which technique is used in work study to record all activities performed by an operator or machine on a single chart?
Answer: Man-machine chart
A man-machine chart records the simultaneous activities of an operator and machine on a time-scaled chart to identify idle periods.
In time study, the rating factor is used to:
Answer: Convert observed time to normal time
The rating factor adjusts observed time to normal time by accounting for the pace of the worker relative to a standard pace.
Which of the following is the correct formula for Standard Time?
Answer: Normal Time × (1 + Allowance Fraction)
Standard Time = Normal Time × (1 + Allowance Fraction), where Normal Time = Observed Time × Rating Factor.
A work sampling study is best suited for:
Answer: Estimating the percentage of time spent on various activities
Work sampling uses random observations over a period to estimate the proportion of time spent on different activities without continuous observation.
In a Methods-Time Measurement (MTM) system, which basic motion has the shortest normal time?
Answer: Grasp
Grasp is generally the shortest basic motion in MTM, as it involves simply closing fingers on an object already in position.
The purpose of a SIMO (Simultaneous Motion) chart is to:
Answer: Record left-hand and right-hand motions simultaneously at a micro-motion level
A SIMO chart records the micro-motions of both hands simultaneously using therblig symbols to identify inefficiencies in hand motions.
Which allowance in work study accounts for fatigue, personal needs, and unavoidable delays?
Answer: PFD allowance
PFD (Personal, Fatigue, and Delay) allowance is added to normal time to account for worker fatigue, personal time, and unavoidable delays.
