Ch. 8 Flashcards
A method of time study where all works has been reduced to basic motions and these are measured in time values
Pre- Determined Time Study.
Benefits of PTS
Assits in training the operator of using the best method. settle grievances in connection with time standards. Devolop the best method. best labor costs. establish time standards. better justify better tooling.
the first two steps of pts
workstation design and motion patterns
a set of motions with shortened names for tasks.
Therblig . 17 of them
A tool used to analyze human work. used to design work that is reasonable for operators.
Modular Arragenment of Predetermined Time Standards. MODAPTS
who developed MODPATS
Chris Heyde.
what does MODPATS stand for
Modular Arrangement of Predetermined Time Standards.
Modapts time values are expressed in
MODS: one value: 0.129 s
Elemental Data COdes
alphabetic includes an activity. numeric indicates time values
All body movements can be expressed in a single unit
Modular Concept. the unit is the MOD.
MODApts three basic motions.
Motion. terminal. Auxiaalry.
modapt motions that are done at the end of a movement.
terminal
MODAPT all other activties that our not performed by the hands/other body parts
Auxiallry
MODAPT activities that our performed with the body during the start of the movement
Motion
an action of the finger, hand, arm and is ually to or from a location
the element Move. 3 types
movments example
Mnumber body parts. then times the amount of movements it takes to complete an action.
Three types of moves
- the action of getting/putting. back and forth movement (saw motion). 3.
Peromed with 30 with arm and
Trunk
two types of terminal activities
Get- you take something. put-
two levels of diffucity for get and put terminal activities: requires a degree of muscular control. is mostly an automatic repsonse
high consciousness control. low consciousness control.
Get with feedback

Auxiliary activities exmaples
R read. Bend and arise B . Sit and stand. Eye control E. Use- do not terminate in a get or put.
