(From: International MODAPTS Association, Inc. Kalamazoo, MI)1Predetermined Time SystemsTechniques for studying work methodsWork is divided into micro elements that are standard in any activityThese micro elements are represented by symbols.Note that in MTM system these symbols are called therbligs.

2StepsDetermine all the symbols in a work processAssign standard time values to each micro movementTotal up the times to find total time/task(Assuming additivity and independence)

3How to be usedDetermine an efficient work methodDetermine the time/unit for an efficient work methodMODAPTS uses modules (MOD) to express units of human physical work (normal time- done by qualified, thoroughly experienced employee)1 MOD = .129 sec. 1 sec. = 7.75 MOD1 MOD = .00215 min. 1 min. = 465 MOD1 MOD = .000036 hr. 1 hr. = 27933 MOD (Standard time with no allowances)MODAPTS codesType of activity + Time to completeM3P2,W5, etc.

4MODAPTS Classes of MotionsMovementDone by the finger-hand-arm-shoulder trunk systemRequired to position a part of the arm to perform the Terminal activitiesTerminal Activities (GET and PUT)Done at the end of a movementIn close proximity to the things being worked onAuxiliary ActivitiesWalking, bending, inspection, deciding, etc.

5MovementMovements and terminal activities take place in pairs.Movement first then terminal activitiesMove to get, move to putExamples: M3GO (move to touch)Movement activities are classified by:Distance movedBody part required to perform the moveLight/small objects vs. heavy/large objectsLarge objects : 16 x 16 x 16Heavy objects : over 18 lbs.Award the lowest category that is possible to successfully complete the activity

It increases distances not time.8ExamplesM1 MovementsRub your thumb and index finger togetherDepressing keys M1P0Squeezing trigger M1P0M2 MovementsFollowing a body move: 5 x W5, M2G1Positioning of a washer: M4G3 M2P5M3 MovementsTurning over the pageDraw a free hand line approximately 6 inches longHow about half an inch long?M4 MovementsAn imaginary 45 degree coneMove forward 18 (inside the cone)9Examples (cont.)M5 MovementsOutside imaginary 45 degree cone Reaching up to an object from a high shelf M5P2Moving an object across the body M5P0M7 MovementsFully up, down, or across the body (hinged at the waist)Picking up objects from the floor M7G1 M7P0

10ExercisesHand moves are typically______inchesWhole arm move forward 15_______Hand turns a nut down______Reach to the floor while standing______Using a pen or pencil perform the following and provide the correct code:Carry the object from I-10 to J-10_______Turn your wrist to view the bottom of the object________Carry the object to imaginary point H-20_______Return the object to G-16_______Carry the object to K-1_______11Moves with Large/Heavy ObjectsWeight LimitMaximum Distance For Large Object Only261218243539ONE0-2 lbM2M3M4M5M7M7M7HAND2-9 lbM3M3M4M5M7M7M79-18 lbM4M4M4M5M7M7M7TWO18-35 lbM4M4M4M4M4M5M7HAND35-136 lbM7M7M7M7M7M7M712Exercises One handMove a 14 lb. box 14 ________Move a 18 lb. box 3 _________Two handsMove a 100 lb. box 6 _________ Move a 40 lb. box 34 _________Move a 30 lb. box 10 _________13Terminal Activities PUT and GET must be joined to a moveInfluenced by:Muscular control: precisionVisual control: eye actionMental control: mental decisionLow conscious control (G0, G1, P0)Automatic responseLittle muscular control, no visual or mental controlHigh conscious control (P2, P5, G3)What is done at the end of move?14Terminal Activities (cont.)TypeConscious ControlDescriptionHigh*LowG0XTouch onlyG1XPick up easy objectP0XNo consciousG3XPick up flat object,or objects in a bin, hard to pick up objectP2XRequires one feedback** (information)P5XRequires two feedbacks*Employees are required to follow an activity through the end, using their eyes**Provided by the employees eyes15Terminal Activities (cont.)For each activity below, is it high or low conscious?Pick up a pencil from an uncluttered desk. ________Pick up a straight pin from an uncluttered desk. ________Pick up a match from a matchbox. _______Put your pencil point exactly on the period at this sentence end. _________Put your pencil anywhere on this page. _________16Simultaneous ActivitiesAlways use an M2 to precede the second high conscious control activityLeft hand -----movement--High control activity at end Right hand----simo-movement---wait----M2 moveHigh control activity at end Both low conscious control: record the highest total MODOne low , one high conscious control: record on the total high conscious control activity MOD valueBoth high conscious control: sum of MOD values from both hands

19GET with Large/Heavy ObjectsG2: One hand engagement Picking up a suitcaseG4: Two hand engagements Unobstructed object, free standing, unimpeded by othersBend over, grasps an object with two hands and returns to a standing position- M7G4 M7P0 G8: Three hand engagements Slightly impeded by othersOne hand- pull the box away, two hands pick it up

20PUT with Small/Light ObjectsP0: Simple put (general or indefinite location)Sliding an object against a stopPicking up a small object and placing it in the other hand M4G3 M4P0Tossing object into box M3P0P2: Put with feedback (definite location)Requiring only one feedback form one or more of senses (usually eyes)Locate Phillips screwdriver in slot M3P2 P5: Put with feedbacks (exact location)More than one correcting motion, and more than one change in directionPutting a screwdriver blade into a slotted screw head- M4P5Placing nut on bolt- M4P5

21PUT with Large/Heavy ObjectsP0: General location (no orderliness) Hand does not touch object againPlace 40 lb. box on table ______P2: With orderliness Hand do not touch object againPlace 40 lb. box to table edge _____P5: One new contact (exact location) Using one additional hand engagement once the object is placed downModerately heavy box placed exactly in line with others

22ExercisesLean over, pick up a carton, and return to a standing position before walking _______Place a pencil point where two lines cross ______Begin with hands in the printed areaPick up a pencil at C-14, put point on F-9 _______Pick up a pin at C-14, put point on E-10 _______Pick up a washer at I-9, put in other hand _______Slide a washer from H-9 off the table into the lap _______With both hands, slide the ruler up to line F _______ Pick up the pencil near the sharp end with the left hand, from B-4. Pick up the washer with the right hand from B-13. While carrying these to the print area, put the washer on the pencil. Slide the washer along to the end of the pencil. ___________Pick up a washer from B-14 and then one from B-9 with the right hand. Return to rest in the approximate starting position. ___________23Auxiliary Activities J2: JuggleTwo criteriaThe object is already in the control of the operator and better control is requiredAll other activity must stopPlace a nut on a screw while there are several nuts in the palm rolling the nut out from the palm_______X4: Apply extra forceAll other motion stops, and then the body braces itselfB17: Bend and arise (if hand goes below the knee)S30: Sit and stand (up and down movement)W5: Walk
