Question Description

please find the attached files to make a lab report using the time study form using the screenshots provided. the operation was ( the lab TA was holding a large screw . he would put a washer on the end of the screw . flip it and put on 3 colored tubes on the screw and then put another washer to secure them in place.) washer--- colored tubes---- washer. find the stopwatch recordings to fill the form and make a diagram. each job consist of three tasks( meaning he put s the washer on then flips the screw to insert the colored. tubes on top of the screw then crew another washer on to secure. in the case each job would have 3 clicks on the stop watch. will include the story watch screen shot after you accept

1. 2. 3. 4. 5. Short Memo Report - Content 1.1. The memo needs a clear objective, -2 1.2. Mention the key findings; think about what the reader needs to know. If it’s on the time study sheet, that’s not enough, else you’d just submit the sheet directly. Think of the report as the summary. What came from doing this time study? Anything? -2 1.3. What other info about the time study is important to know, that the reader can’t have known not being there? -2 Short Memo Report - Style 2.1. Grammar, spelling, professional appearance, and/or proper figure references is lacking, -1 2.2. Required template not followed, and/or report is too long -1 2.3. Subject line needs to contain specific report content, -1 Monkey Puzzle DTS - Content 3.1. Elemental descriptions needs to be clear enough that another person can follow the same method you did, and end each one at the same point in the process. -2 3.2. Foreign elements need to be denoted properly. -1 3.3. Missing times needs to be documented. -2 3.4. Include the continuous stopwatch time! -2 3.5. Include the total standard time on the right side of the summary section, -2 3.6. You need to ensure that you summarize your times correctly. -2 3.7. Fill in the entirety of the Time Check section, like TEBS, TEAF, and the following boxes even if they are zero! -1 3.8. Make sure you put the total allowance of 15% in the Allowance Summary area on the bottom right of the sheet as well. -1 Monkey Puzzle DTS - Style 4.1. You image is difficult to read, try using the scanner in the library next time. -1 4.2. You need to fill in ​all​ the boxes up top on the Time Study Observation Form (Study No. - Observer) , -1 Monkey Puzzle AFD - Content 5.1. How far did travel take up? Make a mention of some scaling or distance on the diagram as a rough estimate. -1 5.2. The TA went to the water fountain, didn’t s/he? You need to make a mention of that somewhere! -2 5.3. Ensure that you draw the bins in the actually seen orientation. Some were supposed to be off kilter, and that needs to be reflected in the drawing accurately! -2
Direct Time Study ( Stopwatch Method) To Do List  1. Today’s class objectives  2. Briefly review of Direct Time Study  3. Practice  4. Monkey Puzzle  5. Assignment overview Objectives  1. To gain skill in stopwatch timing  2. To practice proper time study procedures and calculations Exercise  1. Practice timing using a practice video tape. Students will break the job into three elements, time the operations for approximately 10 cycles using the Continuous Timing Method Exercise (Cont.)  2. Practice timing a live operation. We will simulate an actual time study of a task using the skills developed with the practice video tape. This will include:  Identification of elements and end points,  Observation of element times  Time check and calculation of recording error  Actual runtime recording  All standard time calculation Why do we use Direct Time Study(DTS)  Is a study of the operational steps or production procedure and the time consumed by them, for the purpose of increasing efficiency or productivity of workers  Time study is used to calculate the standard time for a job.  The operations should be divided into groups of motions known as ‘elements’.  Compromise is made between the element length and reading accuracy when choosing the element points. Snapback VS. Continuous – Snapback method ● Start watch at beginning of every element. ● “Snap” watch back to zero at end of element. ● Record time. ● Advantages  – Element variations easily observable  – No subtraction – Continuous method ● Start watch at beginning of observation ● Record elapsed time at end of each element. ● Let it run … ● Advantages  – Not so much manipulation of stopwatch  – Elements not so easily omitted  – Regular/irregular elements more readily distinguished Steps of Time Study 1. Watch the process for several times to get familiar with the work 2. Obtain and record all the job information. 3. Breakdown the operation into “elements.” 4. Record the time taken to perform each “element”. 5. Assess the effective working speed of the operator. 6. Extend the observed times to “basic times.” 7. Determine the allowances to be made above the “basic time” 8. Determine the “standard time” for the operation. Work Elements  Series of motion activities logically grouped because of unified purpose. ● Guideline: – Each work element should consist of a logical group of motion elements. ● e.g., reach, grasp, move, place – Beginning point of one element should be end of previous. ● No time gap between elements. – Each element should have readily identifiable end point. ● i.e., easily detected, no ambiguity – Work elements should not be too long. ● < “several” min – Work elements should not be too short. ● > 3 sec Performance Rate Watch Time Observed Time Normal Time = ∑ OT Time elapsed before Study Notes for recording on DTS form  When missing a reading, indicate ‘M’ in the W column. Do not approximate with any values. Too many missing values in the form will lead to more than 2% error.  Unavoidable delays such as tool breakage, talking to supervisor, using rest rooms should be referred as foreign elements. This should be documented in the ‘Foreign Elements’ box in the time study form.  The foreign element times should be deducted from the observed time (OT). Performance Rating  A normal operator, defined as a qualified, thoroughly experienced operator working under customary conditions, will be given 100% PR.  A slow operator will get less than 100% and the quick operator will get more than 100% PR.  On short cycle, repetitive work, it is customary to apply one rating to entire study.  If the rating is different for each cycle, then normal time (NT) should be calculated for each element. If it is same for entire study, then total NT is calculated from the total OT. Allowances  Since the foreign elements (delays) should have been removed in determining the NT, allowance must be added (see allowance summary column in the form).  If not mentioned, 15% should be given for manual operations and 10% for machine elements. Calculations (Summary box)  Total OT = ∑ OT of all cycles.  Rating: mention the rating if it same for all the cycles.  Total NT = ∑ NT of all cycles; or convert it from total OT if rating is same for all the cycles.  No. of observations.  Average NT = Total NT / No. of observations.  % allowance (15 %, if not mentioned).  Elemental Standard time = avg. NT X ( 1 + allowance ).  No. occurrences: how many time the same element is repeated in the cycle. Normally is it one.  Standard time: Elemental std. time X No. occurrences.  Add all the elemental standard time to get the total standard time. Calculations (Time Check Box)  TEBS = time elapsed before study; TEAF = time elapsed after study.  Total Check time = TEBS + TEAF  Effective time = ∑ total OT  Ineffective time = ∑ all foreign element time  Total recorded time = add (check time + Effective Time + ineffective Time)  Unaccounted time = total recorded time – elapsed time  Error= Unaccounted time / Total recorded time
EIND313 – Work Design and Analysis Direct Time Study Laboratory (Continuous Stopwatch Method) DUE: 02/19/17 5:00 pm for Tuesday Labs and 02/21/17 5:00 pm for Thursday Labs Objectives The objectives of the Direct Time Study lab are to: • acquire skill in stopwatch timing • practice proper time study procedures and calculations • practice writing a short memo report to communicate the time study results In-Lab Exercise We will do two exercises in lab this week. 1. Practice timing using a practice video tape. Students will break the job into three elements, time the operations for approximately 10 cycles using the continuous timing method, and do the standard time calculations. We will repeat this as many times as necessary until everyone is reasonably proficient. 2. Practice timing a live operation. We will simulate an actual time study of a task using the skills developed above in the practice session. This live exercise will include: a. identification of elements and end points b. observation of element times c. time check and calculation of recording error d. actual runtime recordings e. all standard time calculations i. performance rating = 90% ii. APFD = 15 % ***Note that you are trying to achieve a recording error below 2%.*** Assignment Consider that you are part of a consulting group doing this work as a contract for an industrial company or government agency. Assume your reader will have previous general technical background in industrial engineering but do not assume specific knowledge of your study, the process and other details.
