Work Measurement (TEST 1) Flashcards
What is work measurement
determines how long a job takes
What are time standards used for
Cost allocations
Production & Inventory Control
Evaluation of alternatives
Acceptable days work
Incentive Pay
Normal Time
Observed Time * rating
Shift allowance
Standard Time =
(normal time)/(1 - Allowances)
Work Allowance
Standard Time =
Normal Time(1 + Allowances)
Most common
Typical personal allowance
5% unless there is a fatigue allowance then it is 0
Methods for determining fatigue allowance
add points based on the tables
or
add variable fatigue using a coefficient of fatigue:
F = (T-t)/T * 100%
F = coefficient of fatigue
T = operation time at end of period
t = operation time at beginning of period
What is the primary cause for incorrect standard times
failure to adjust for learning
What does a learning curve describe
how the time it takes a worker or organization to do a task decreases with experience and repitition
Learning curve formula
Y = ax^b
Y = cycle time for x cycle
a = time for cycle 1
x = cycle # of interest
b = learning curve slope (Table 24.15)
